Summary

  • The 70th anniversary of the adoption of the 1949 Geneva Conventions was commemorated in 2019. But violations of the Conventions and of the 1977 Additional Protocols are widespread.
  • Contemporary conflicts have been marked by violations of some of the foundational rules of international humanitarian law (IHL) relating to the protection of the wounded and sick and of providers of medical assistance.
  • A further area of IHL that has come under strain and scrutiny are the rules regulating humanitarian relief operations and their application to sieges and blockades.
  • War has a huge impact on children, and the treatment of children in armed conflict is another area of the law that requires further attention.
  • In the current political climate, it is unlikely that new treaties will be negotiated to address emerging issues or uncertainties in the law.
  • Other measures must be explored, including the adoption of domestic measures to implement existing law; support for processes that interpret the law; and initiatives to promote compliance with the law by organized armed groups.
  • One overarching challenge is the interplay between IHL and counterterrorism measures. It can undermine the protections set out in IHL, and hinder principled humanitarian action and activities to promote compliance with the law by organized armed groups.

How Regulation Could Break the Internet: In Conversation with Andrew Sullivan

Research Event

19 June 2019 - 6:00pm to 7:00pm

Chatham House | 10 St James's Square | London | SW1Y 4LE

Chair: Emily Taylor, Associate Fellow, International Security Department, Chatham House; Editor, Journal of Cyber Policy

Internet regulation is increasing around the world creating positive obligations on internet providers and exerting negative unintended consequences on the internet infrastructure. In some ways, most of this regulatory activity is justifiable. Governments are concerned about the increased risk that the use of the internet brings to societies. As a response, many governments have been enacting regulations as their main approach to dealing with these concerns. The main challenge is that most of the current regulations are either ill-defined or unworkable.  

On the one hand, several governments have established procedures that seek to analyze the impacts of new regulatory proposals before they were adopted. However, there hasn’t been enough attention aimed at analyzing regulations after they have been adopted and only a few have measures in place to evaluate the impacts of the procedures and practices that govern the regulatory process itself.

On the other hand, much of the regulation creates unintended consequences to the internet itself. It undermines many of its fundamental properties and challenges the integrity and resiliency of its infrastructure.  

This event discusses current practices in internet-related regulation and the related challenges. Panellists will discuss how governments can enforce regulations that achieve their intended purpose while at the same time protecting the internet’s core infrastructure and its properties, including its openness, interoperability and global reach.

Protecting Children in Conflict: See Me Safe Symposium

Invitation Only Research Event

7 May 2019 - 10:00am to 5:00pm

Chatham House, London

Today there are 420 million children, or one-fifth of children worldwide, who live in conflict zones and are at risk of being killed or injured and denied access to education, healthcare and humanitarian assistance. From Myanmar and Syria, to South Sudan and Yemen, the impact of conflict on children and their families is devastating. With conflicts becoming more protracted and urbanized, and the undermining of international rules and norms, the risk to civilians is rapidly increasing. 
 
The impact of the crisis in civilian protection is not only devastating children’s lives and risking a lost generation, it threatens global stability and prosperity, contributing to the degradation of the international rules-based system and its institutions and undermining the ability to hold perpetrators accountable and prevent these atrocities from happening.
 
This symposium will bring together practitioners, policymakers, business leaders, philanthropists and academics for a day of panel discussions on the protection of children in conflict. The aim of the event is to generate an informed debate and to deepen engagement with issues around protecting children in conflict as well as to inspire support to help rebuild children’s lives.
 
This event will be followed by a reception from 17:00-18:30.
 
Attendance is by invitation only.
 
Celebrating its centenary in 2020, Chatham House is partnering with Save the Children on this core area of their work, in their anniversary year.

Create a Global Code of Conduct for Outer Space

12 June 2019

Dr Patricia Lewis

Research Director, Conflict, Science & Transformation; Director, International Security Programme
The rules governing human activity in space have been in place for only a few decades, and yet they are already out of date. They need to be built on and extended to reflect the dramatic and rapid changes in the use of space.

2016-09-27-Space2.jpg

The 1967 Outer Space Treaty (OST) is the mainframe for space law. It recognizes the importance of the use and scientific exploration of outer space for the benefit and in the interests of all countries. It also prohibits national sovereignty in space, including of the Moon and other celestial bodies.

The OST prohibits all weapons of mass destruction in space – in orbit or on other planets and moons – and does not allow the establishment of military infrastructure, manoeuvres or the testing of any type of weapon on planets or moons. As the treaty makes clear, outer space is for peaceful purposes only. Except of course, it is not – nor has it ever been so.

The very first satellite, Sputnik, was a military satellite which kicked off the Cold War space race between the US and the USSR. The militaries of many countries followed suit, and space is now used for military communication, signals intelligence, imaging, targeting, arms control verification and so on.

However, in keeping with international aspirations, space is also being used for all kinds of peaceful purposes such as environmental monitoring, broadcast communications, delivering the internet, weather prediction, navigation, scientific exploration and – very importantly – monitoring the ‘space weather’ (including the activity from the Sun).

There are several other international agreements on space, such as on the rescue of astronauts, the registration of satellites and liability for damage caused by space objects. There is also the Moon Treaty, which governs activities on the Moon and other moons, asteroids and planets.[i]

More recently, states at the UN Committee on the Peaceful Uses of Outer Space (COPUOS) in Vienna have agreed on guidelines to deal with the worrying situation of space debris which is cluttering up orbits and posing a danger to satellites, the space station and astronauts.

The problem the international community now faces is that the use of space is changing dramatically and rapidly. There are more satellites than ever – well over 1,000 – and more owners of satellites – almost every country uses information generated from space. Increasingly, however, those owners are not countries, militaries or international organizations but the commercial sector. Very soon, the owners will even include individuals.

Small ‘mini-satellites’ or ‘cube-sats’ are poised to be deployed in space. These can act independently or in ‘swarms’, and are so small that they piggy-back on the launching of other satellites and so are very cheap to launch. This is changing the cost–benefit equation of satellite ownership and use. Developing countries are increasingly dependent on space for communications, the internet and information on, for example, weather systems, coastal activities and agriculture. 

Another major development is the advent of asteroid mining. Asteroids contain a wide range of metals and minerals – some asteroids are more promising than others, and some are closer to Earth than others. Several companies have been set up and registered around the world to begin the exploitation of asteroids for precious metals (such as platinum) and compounds (such as rare-earth minerals).

Legally, however, this will be a murky venture. The current international treaty regime prohibits the ownership of a celestial body by a country – space is for all. But does international law prohibit the ownership or exploitation of a celestial body by a private company? The law has yet to be tested, but there are space lawyers who think that companies are exempt. Luxembourg and Australia are two countries that have already begun the registration of interest for space-mining companies.

As humanity becomes more dependent on information that is generated in or transmitted through space, the vulnerability to the manipulation of space data is increasing. The demands on the use of communications frequencies (the issue of spectrum availability and rights), managed by the International Telecommunication Union (ITU),[ii] need to be urgently addressed.

There are now constant cyberattacks in space and on the digital information on which our systems rely. For example, position, navigation and timing information such as from GPS or Galileo is not only vital for getting us safely from A to B, but also for fast-moving financial transactions that require accurate timing signals.

Almost all of our electronic systems depend on those timing signals for synchronization and basic functioning. Cyber hacks, digital spoofing and ‘fake’ information are now a real possibility. There is no rules-based order in place that is fit to deal with these types of attacks.

Cyberweapons are only part of the problem. It is assumed that states, if they haven’t already done so, will be positioning ‘defensive’ space weaponry to protect their satellites. The protection may be intended to be against space debris – nets, grabber bars and harpoons, for example, are all being investigated.

All of these ideas, however, could be used as offensive weapons. Once one satellite operator decides to equip its assets with such devices, many others will follow. The weaponization of space is in the horizon.

There are no international rules or agreements to manage these developments. Attempts in Geneva to address the arms race in space have floundered alongside the inability of the Conference on Disarmament to negotiate any instrument since 1996.

Attempts to develop rules of the road and codes of conduct, or even to begin negotiations to prohibit weapons in space, have failed again and again. There are no agreed rules to govern cyber activity. The Tallinn Manuals[iii] that address how international law is applicable to cyberwarfare also address the laws of armed conflict in space, but data spoofing and cyber hacking in space exist in far murkier legal frameworks.

The current system of international space law – which does not even allow for a regular review and consideration of the OST – is struggling to keep up. Space is the inheritance of humankind, yet the current generation of elders – as they have done with so many other parts of our global environment – have let things go and failed to shepherd in the much-needed system of rules to protect space for future generations.

It is not too late, but it will require international cooperation among the major space players: Russia, the US, China, India and Europe – hardly a promising line-up of collaborators in the current political climate.

Filling the governance gaps

Norms of behaviour and rules of the road need to be established for space before it becomes a 21st-century ‘wild west’ of technology and activity. Issues such as cleaning up space debris, the principle of non-interference, and how close satellites can manoeuvre to each other (proximity rules) need to be agreed as a set of international norms for space behaviour.

A cross-regional group of like-minded countries (for example Algeria, Canada, Chile, France, India, Kazakhstan, Malaysia, Nigeria, Sweden, the UAE and the UK) should link up with UN bodies, including the Office for Outer Space Affairs (UNOOSA), COPUOS and ITU, and key private-sector companies to kick-start a new process for a global code of conduct to establish norms and regulate behaviour in space.

The UN could be the host entity for this new approach – or it could be established in the way the Ottawa process for landmines was established, by a group of like-minded states with collective responsibility for, and collective hosting and funding of, the negotiations.

A new approach should also cover cybersecurity in space. The UN processes on space and cyber should intersect more to find ways to create synergies in their endeavours. And the problems ahead as regards spectrum management – particularly given the large number of small satellites and constellations that are to be launched in the near future – need urgent attention in ITU.

What needs to happen

  • The international rules-based order for space – enshrined in particular in the 1967 Outer Space Treaty – has not kept pace with the rapid and dramatic changes in the use of space. New norms of behaviour and rules of the road are needed.
  • These norms and rules need to address a host of contemporary or prospective developments, including asteroid mining, increased numbers of satellite owners, the emergence of ‘mini-satellites’, cyberwarfare, and the potential deployment of ‘defensive’ space weaponry to protect satellites.
  • A cross-regional group of like-minded countries should link up with UN bodies – including UNOOSA, COPUOS and ITU – and key private-sector companies to kick-start a new process for developing a global code of conduct.
  • Problems related to radio spectrum management – given the large number of small satellites and constellations to be launched in the near future – need urgent attention in ITU.

Human Control Is Essential to the Responsible Use of Military Neurotechnology

8 August 2019

Yasmin Afina

Research Assistant, International Security Programme
The military importance of AI-connected brain–machine interfaces is growing. Steps must be taken to ensure human control at all times over these technologies.

2019-08-08-BABWIB.jpg

Technological progress in neurotechnology and its military use is proceeding apace. As early as the 1970s, brain-machine interfaces have been the subject of study. By 2014, the UK’s Ministry of Defence was arguing that the development of artificial devices, such as artificial limbs, is ‘likely to see refinement of control to provide… new ways to connect the able-bodied to machines and computers.’ Today, brain-machine interface technology is being investigated around the world, including in Russia, China and South Korea.

Recent developments in the private sector are producing exciting new capabilities for people with disabilities and medical conditions. In early July, Elon Musk and Neuralink presented their ‘high-bandwidth’ brain-machine interface system, with small and flexible electrode threads packaged into a small device containing custom chips and to be inserted and implanted into the user’s brain for medical purposes.

In the military realm, in 2018, the United States’ Defense Advanced Research Projects Agency (DARPA) put out a call for proposals to investigate the potential of nonsurgical brain-machine interfaces to allow soldiers to ‘interact regularly and intuitively with artificially intelligent, semi-autonomous and autonomous systems in a manner currently not possible with conventional interfaces’. DARPA further highlighted the need for these interfaces to be bidirectional – where information is sent both from brain to machine (neural recording) and from machine to brain (neural stimulation) – which will eventually allow machines and humans to learn from each other.

This technology may provide soldiers and commanders with a superior level of sensory sensitivity and the ability to process a greater amount of data related to their environment at a faster pace, thus enhancing situational awareness. These capabilities will support military decision-making as well as targeting processes.

Neural recording will also enable the obtention of a tremendous amount of data from operations, including visuals, real-time thought processes and emotions. These sets of data may be used for feedback and training (including for virtual wargaming and for machine learning training), as well as for investigatory purposes. Collected data will also feed into research that may help researchers understand and predict human intent from brain signals – a tremendous advantage from a military standpoint.

Legal and ethical considerations

The flip side of these advancements is the responsibilities they will impose and the risks and vulnerabilities of the technology as well as legal and ethical considerations.

The primary risk would be for users to lose control over the technology, especially in a military context; hence a fail-safe feature is critical for humans to maintain ultimate control over decision-making. Despite the potential benefits of symbiosis between humans and AI, users must have the unconditional possibility to override these technologies should they believe it is appropriate and necessary for them to do so.

This is important given the significance of human control over targeting, as well as strategic and operational decision-making. An integrated fail-safe in brain-machine interfaces may in fact allow for a greater degree of human control over critical, time-sensitive decision-making. In other words, in the event of incoming missiles alert, while the AI may suggest a specific course of action, users must be able to decide in a timely manner whether to execute it or not.

Machines can learn from coded past experiences and decisions, but humans also use gut feelings to make life and death decisions. A gut feeling is a human characteristic that is not completely transferable, as it relies on both rational and emotional traits – and is part of the ‘second-brain’ and the gut-brain axis which is currently poorly understood. It is however risky to take decisions solely on gut feelings or solely on primary brain analysis—therefore, receiving a comprehensive set of data via an AI-connected brain-machine interface may help to verify and evaluate the information in a timely manner, and complement decision-making processes. However, these connections and interactions would have to be much better understood than the current state of knowledge. 

Fail-safe features are necessary to ensure compliance with the law, including international humanitarian law and international human rights law. As a baseline, human control must be used to 1) define areas where technology may or may not be trusted and to what extent, and 2) ensure legal, political and ethical accountability, responsibility and explainability at all times. Legal and ethical considerations must be taken into account from as early as the design and conceptualizing stage of these technologies, and oversight must be ensured across the entirety of the manufacturing supply chain.  

The second point raises the need to further explore and clarify whether existing national, regional and international legal, political and ethical frameworks are sufficient to cover the development and use of these technologies. For instance, there is value in assessing to what extent AI-connected brain-machine interfaces will affect the assessment of the mental element in war crimes and their human rights implications.

In addition, these technologies need to be highly secure and invulnerable to cyber hacks. Neural recording and neural stimulation will be directly affecting brain processes in humans and if an adversary has the ability to connect to a human brain, steps need to be taken to ensure that memory and personality could not be damaged.

Future questions

Military applications of technological progress in neurotechnology is inevitable, and their implications cannot be ignored. There is an urgent need for policymakers to understand the fast-developing neurotechnical capabilities, develop international standards and best practices – and, if necessary, new and dedicated legal instruments – to frame the use of these technologies.

Considering the opportunities that brain-machine interfaces may present in the realms of security and defence, inclusive, multi-stakeholder discussions and negotiations leading to the development of standards must include the following considerations:

  • What degree of human control would be desirable, at what stage and by whom? To what extent could human users be trusted with their own judgment in decision-making processes?
  • How could algorithmic and human biases, the cyber security and vulnerabilities of these technologies and the quality of data be factored into these discussions?
  • How can ethical and legal considerations be incorporated into the design stage of these technologies?
  • How can it be ensured that humans cannot be harmed in the process, either inadvertently or deliberately?
  • Is there a need for a dedicated international forum to discuss the military applications of neurotechnology? How could these discussions be integrated to existing international processes related to emerging military applications of technological progress, such as the Convention on Certain Conventional Weapons (CCW) Group of Governmental Experts on Lethal Autonomous Weapons Systems?

Who’s Afraid of Huawei? Understanding the 5G Security Concerns

9 September 2019

Emily Taylor

Associate Fellow, International Security Programme
Emily Taylor examines the controversy around the Chinese tech giant’s mobile broadband equipment and the different approaches taken by Western countries.

2019-09-06-Huawei.jpg

As countries move towards the fifth generation of mobile broadband, 5G, the United States has been loudly calling out Huawei as a security threat. It has employed alarmist rhetoric and threatened to limit trade and intelligence sharing with close allies that use Huawei in their 5G infrastructure.

While some countries such as Australia have adopted a hard line against Huawei, others like the UK have been more circumspect, arguing that the risks of using the firm’s technology can be mitigated without forgoing the benefits.

So, who is right, and why have these close allies taken such different approaches?

The risks

Long-standing concerns relating to Huawei are plausible. There are credible allegations that it has benefitted from stolen intellectual property, and that it could not thrive without a close relationship with the Chinese state.

Huawei hotly denies allegations that users are at risk of its technology being used for state espionage, and says it would resist any order to share information with the Chinese government. But there are questions over whether it could really resist China’s stringent domestic legislation, which compels companies to share data with the government. And given China’s track record of using cyberattacks to conduct intellectual property theft, there may be added risks of embedding a Chinese provider into critical communications infrastructure.

In addition, China’s rise as a global technological superpower has been boosted by the flow of financial capital through government subsidies, venture and private equity, which reveal murky boundaries between the state and private sector for domestic darlings. Meanwhile, the Belt and Road initiative has seen generous investment by China in technology infrastructure across Africa, South America and Asia.

There’s no such thing as a free lunch or a free network – as Sri Lanka discovered when China assumed shares in a strategic port in return for debt forgiveness; or Mexico when a 1% interest loan for its 4G network came on the condition that 80% of the funding was spent with Huawei.

Aside from intelligence and geopolitical concerns, the quality of Huawei’s products represents a significant cyber risk, one that has received less attention than it deserves.

On top of that, 5G by itself will significantly increase the threat landscape from a cybersecurity perspective. The network layer will be more intelligent and adaptable through the use of software and cloud services. The number of network antennae will increase by a factor of 20, and many will be poorly secured ‘things’; there is no need for a backdoor if you have any number of ‘bug doors’.

Finally, the US is threatening to limit intelligence sharing with its closest allies if they adopt Huawei. So why would any country even consider using Huawei in their 5G infrastructure?

Different situations

The truth is that not every country is free to manoeuvre; 5G technology will sit on top of existing mobile infrastructure.

Australia and the US can afford to take a hard line: their national infrastructure has been largely Huawei-free since 2012. However, the Chinese firm is deeply embedded in other countries’ existing structures – for example, in the UK, Huawei has provided telecommunications infrastructure since 2005. Even if the UK decided tomorrow to ditch Huawei, it cannot just rip up existing 4G infrastructure. To do so would cost a fortune, risk years of delay in the adoption of 5G and limit competition in 5G provisioning.

As a result, the UK has adopted a pragmatic approach resulting from years of oversight and analysis of Huawei equipment, during which it has never found evidence of malicious Chinese state cyber activity through Huawei.

At the heart of this process is the Huawei Cyber Security Evaluation Centre, which was founded in 2010 as a confidence-building measure. Originally criticized for ‘effectively policing itself’, as it was run and staffed entirely by Huawei, the governance has now been strengthened, with the National Cyber Security Centre chairing its oversight board.

The board’s 2019 report makes grim reading, highlighting ‘serious and system defects in Huawei’s software engineering and cyber security competence’. But it does not accuse the company of serving as a platform for state-sponsored surveillance.

Similar evidence-based policy approaches are emerging in other countries like Norway and Italy. They offer flexibility for governments, for example by limiting access to some contract competition through legitimate and transparent means, such as security reviews during procurement. The approaches also raise security concerns (both national and cyber) to a primary issue when awarding contracts – something that was not always done in the past, when price was the key driver.

The UK is also stressing the need to manage risk and increase vendor diversity in the ecosystem to avoid single points of failure. A further approach that is beginning to emerge is to draw a line between network ‘core’ and ‘periphery’ components, excluding some providers from the more sensitive ‘core’. The limited rollouts of 5G in the UK so far have adopted multi-provider strategies, and only one has reportedly not included Huawei kit.

Managing the risks to cyber security and national security will become more complex in a 5G environment. In global supply chains, bans based on the nationality of the provider offer little assurance. For countries that have already committed to Huawei in the past, and who may not wish to be drawn into an outright trade war with China, these moderate approaches offer a potential way forward.

Who Runs the Internet: Internet Consolidation and Control

Research Event

10 December 2019 - 6:00pm to 7:15pm

Chatham House, London

Event participants

Andrew Sullivan, President and CEO, Internet Society
Jennifer Cobbe, Research Associate, Department of Computer Science and Technology, University of Cambridge
Jesse Sowell, Assistant Professor, Department of International Affairs, Bush School of Government and Public Service, Texas A&M University
Chair: Emily Taylor, Associate Fellow, International Security, Chatham House, Editor, Journal of Cyber Policy

In recent years, there has been a growing debate around the influence of a few large internet technology companies on the internet’s infrastructure and over the popular applications and social media platforms that we use every day.

The internet which was once widely viewed as a collective platform for limitless, permissionless innovation, competition and growth, is now increasingly viewed as a consolidated environment dominated by a few. Such market dominance threatens to undermine the internet’s fundamental benefits as a distributed network in which no single entity has control.  

The panel examines the risks of consolidation throughout the internet’s technology stack such as the impact on complex supply chains that support applications, including cloud provisions, ‘as a service’.

It also explores the potential benefits, for example, when building out essential infrastructure to support faster and cheaper internet services in developing economies, consolidation can create economies of scale that bring the resource-intensive building blocks of the internet economy within the reach of new start-ups and innovators.

The panel provides an interdisciplinary perspective exploring the relationship between consolidation and evolutions in the internet infrastructure as well as unpacking its policy implications.

This event supports a special issue of the Journal of Cyber Policy as part of a collaboration between Chatham House and the Internet Society which explores the impact of the consolidation on the internet’s fundamental architecture.

Oman’s New Sultan Needs to Take Bold Economic Steps

16 January 2020

Dr John Sfakianakis

Associate Fellow, Middle East and North Africa Programme
The country is in a good regional position, but the economy is at a crossroads.

2020-01-16-SultanHaitham2.jpg

The transition of power in Oman from the deceased Sultan Qaboos to his cousin and the country’s new ruler, Sultan Haitham bin Tariq, has been smooth and quick, but the new sultan will soon find that he has a task in shoring up the country’s economic position.

Above all, the fiscal and debt profile of the country requires careful management. Fiscal discipline was rare for Oman even during the oil price spike of the 2000s. Although oil prices only collapsed in 2014, Oman has been registering a fiscal deficit since 2010, reaching a 20.6 per cent high in 2016. As long as fiscal deficits remain elevated, so will Oman’s need to finance those deficits, predominately by borrowing in the local and international market.

Oman’s Debt-to-GDP ratio has been rising at a worrying pace, from 4.9 per cent in 2014 to an IMF-estimated 59.8 per cent in 2019. By 2024, the IMF is forecasting the ratio to reach nearly 77 per cent. A study by the World Bank found that if the debt-to-GDP ratio in emerging markets exceeds 64 per cent for an extended period, it slows economic growth by as much as 2 per cent each year.

Investors are willing to lend to Oman, but the sultanate is paying for it in terms of higher spreads due to the underlying risk markets are placing on the rising debt profile of the country. For instance, Oman has a higher sovereign debt rating than Bahrain yet markets perceive it to be of higher risk, making it costlier to borrow. Failure to address the fiscal and debt situation also risks creating pressure on the country’s pegged currency.

If oil revenues remain low, Sultan Haitham will have to craft a daring strategy of diversification and private sector growth. He is well placed for this: Sultan Haitham headed Oman’s Vision 2040, which set out the country’s future development plans and aspirations, the first Gulf country to embark on such an assessment. However, like all vision documents in the Gulf, Oman’s challenge will be implementation.

In the age of climate change, renewable energy is a serious economic opportunity, which Oman has to keep pursuing. If cheap electricity is generated it could also be exported to other Gulf states and to south Asia. In Oman, the share of renewables in total electricity capacity was around 0.5 per cent in 2018; the ambition is to reach 10 per cent by 2025.

However, in order to reach this target, Oman would have to take additional measures such as enhancing its regulatory framework, introducing a transparent and gradual energy market pricing policy and integrating all stakeholders, including the private sector, into a wider national strategy.

Mining could provide another economic opportunity for Oman’s diversification efforts, with help from a more robust mining law passed last year. The country has large deposits of metals and industrial minerals and its mountains could have gold, palladium, zinc, rare earths and manganese.

Oman’s strategic location connecting the Gulf and Indian Ocean with east Africa and the Red Sea could also boost the country’s economy. The Duqm special economic zone, which is among the largest in the world, could become the commercial thread between Oman, south Asia and China’s ‘Belt and Road Initiative.’

Oman has taken important steps to make its economy more competitive and conducive to foreign direct investment. Incentives include a five-year renewable tax holiday, subsidized plant facilities and utilities, and custom duties relief on equipment and raw materials for the first 10 years of a firm’s operation in Oman.

A private sector economic model that embraces small- and medium-sized enterprises as well as greater competition and entrepreneurship would help increase opportunities in Oman. Like all other Gulf economies, future employment in Oman will have to be driven be the private sector, as there is little space left to grow the public sector.

Privatization needs to continue. Last year’s successful sale of 49 per cent of the electricity transmission company to China’s State Grid is a very positive step. The electricity distribution company as well as Oman Oil are next in line for some form of partial privatization.

The next decade will require Oman to be even more adept in its competitiveness as the region itself tries to find its new bearings. Take tourism for instance; Oman hopes to double its contribution to GDP from around 3 per cent today to 6 per cent by 2040 and the industry is expected to generate half a million jobs by then. Over the next 20 years, Oman will most likely be facing stiff competition in this area not only by the UAE but by Saudi Arabia as well.

The new sultan has an opportunity to embark on deeper economic reforms that could bring higher growth, employment opportunities and a sustainable future. But he has a big task.

A shaky truce remains broadly in place among rival Libyan forces fighting for control of Tripoli. However, a durable ceasefire to bring an end to the current bout of conflict, which was initiated by Khalifa Haftar’s Libyan Arab Armed Forces’ (LAAF) offensive on the capital in April 2019, has not been reached. In recent weeks attention has focused on talks hosted in Moscow and Berlin, with the former aimed at agreeing a ceasefire and the latter seeking to reach agreement among international actors to bring an end to external military support for Libyan warring actors, and to craft a way forward for future intra-Libyan talks. Yet, there has been little emphasis on Libyan actors – beyond Haftar and prime minister Fayez al-Serraj – in this process.
 
This roundtable will bring together experts and policymakers to discuss means of de-escalating the conflict and seeking a lasting resolution through the development of interconnected intra-Libyan social and security negotiation tracks. Mr Usama Otman Essed of the Libya Center for Strategic and Future Studies (LCSFS) will present his research group’s ideas on these issues and discuss their ongoing efforts to promote dialogue among social and security actors.

Prospects for Reforming Libya’s Economic Governance: Ways Forward

There is a broad consensus that Libya’s rentier, patronage-based system of governance is a driver, and not only a symptom, of Libya’s continuing conflict. The dysfunction of Libya’s economic system of governance has been exacerbated by the governance split that has prevailed since 2014 whereby rival administrations of state institutions have emerged. Despite these challenges, a system of economic interdependence, whereby forces aligned with Field Marshal Haftar control much of the oil and gas infrastructure and the UN-backed Government of National Accord controls the means of financial distribution, has largely prevailed. Yet, at the time of writing, this is under threat: a damaging oil blockade is being implemented by forces aligned with Haftar and those state institutions that do function on a national basis are finding it increasingly difficult to avoid being dragged into the conflict.

This roundtable will bring together analysts and policymakers to discuss these dynamics and look at possible remedies. Jason Pack, non-resident fellow at the Middle East Institute, will present the findings of his latest paper on the issue which recommends the formation of 'a Libyan-requested and Libyan-led International Financial Commission vested with the requisite authorities to completely restructure the economy.' Tim Eaton, who has been leading Chatham House’s work on Libya’s conflict economy, supporting UNSMIL’s efforts in this field, will act as respondent.

Conflict and the Water Crisis in Iraq

Water is a critical issue for Iraq’s future stability and prosperity. Only a few decades ago, the country was one of the most fertile in the region, with two major rivers flowing through it. Today, national and transboundary pollution, mismanagement, and debilitating cycles of conflict have contributed to a situation where only half of current water needs are being met, and where an 80% reduction in the flow of water down the Tigris and Euphrates rivers has led to the loss of millions of acres of formerly productive land and the displacement of rural communities.

Water scarcity can be a driver of violence and conflict. Tribal conflicts over water sources have erupted sporadically in the south and the contamination of municipal water which led to the hospitalization of some 118,000 citizens was a trigger for the large-scale protests in Basra in late 2018. Without concerted action by national and local governments, companies and international agencies, the situation will only worsen as higher temperatures and reduced rainfall drive rural-to-urban migration and increase the risk of drought, food insecurity and water-related diseases.

At this roundtable, part of the Chatham House Iraq Initiative, experts will discuss the domestic, regional and international factors that continue to exacerbate the water crisis in Iraq, and propose solutions, including technical innovation, public sector capacity-building and greater international cooperation, that might contribute to effective state-building, build resilience to the effects of climate change and reduce the risk of further conflict.

Since the overthrow of the regime of Muammar Gaddafi in 2011, Libya’s multitude of armed groups have followed a range of paths. While many of these have gradually demobilized, others have remained active, and others have expanded their influence. In the west and south of the country,  armed groups have used their state affiliation to co-opt the state and professionals from the state security apparatus into their ranks.

In the east, the Libyan Arab Armed Forces projects a nationalist narrative yet is ultimately subservient to its leader, Field Marshal Khalifa Haftar. Prevailing policy narratives presuppose that the interests of armed actors are distinct from those of the communities they claim to represent. Given the degree to which most armed groups are embedded in local society, however, successful engagement will need to address the fears, grievances and desires of the surrounding communities, even while the development of armed groups’ capacities dilutes their accountability to those communities.

This roundtable will discuss the findings of a forthcoming Chatham House research paper, ‘The Development of Libyan Armed Groups Since 2014: Community Dynamics and Economic Interests’, which presents insights from over 200 interviews of armed actors and members of local communities and posits how international policymakers might seek to curtail the continued expansion of the conflict economy.

Summary

  • Libya’s multitude of armed groups have followed a range of paths since the emergence of a national governance split in 2014. Many have gradually demobilized, others have remained active, and others have expanded their influence. However, the evolution of the Libyan security sector in this period remains relatively understudied. Prior to 2011, Libya’s internal sovereignty – including the monopoly on force and sole agency in international relations – had been personally vested in the figure of Muammar Gaddafi. After his death, these elements of sovereignty reverted to local communities, which created armed organizations to fill that central gap. National military and intelligence institutions that were intended to protect the Libyan state have remained weak, with their coherence undermined further by the post-2014 governance crisis and ongoing conflict. As a result, the most effective armed groups have remained localized in nature; the exception is the Libyan Arab Armed Forces (LAAF), which has combined and amalgamated locally legitimate forces under a central command.
  • In the west and south of the country, the result of these trends resembles a kind of inversion of security sector reform (SSR) and disarmament, demobilization and reintegration (DDR): the armed groups have used their state affiliation to co-opt the state and professionals from the state security apparatus into their ranks; and have continued to arm, mobilize and integrate themselves into the state’s security apparatus without becoming subservient to it. In the eastern region, the LAAF projects a nationalist narrative yet is ultimately subservient to its leader, Field Marshal Khalifa Haftar. The LAAF has co-opted social organizations to dominate political and economic decision-making.
  • The LAAF has established a monopoly over the control of heavy weapons and the flow of arms in eastern Libya, and has built alliances with armed groups in the east. Armed groups in the south have been persuaded to join the LAAF’s newly established command structure. The LAAF’s offensive on the capital, which started in April 2019, represents a serious challenge to armed groups aligned with the Tripoli-based Government of National Accord (GNA). The fallout from the war will be a challenge to the GNA or any future government, as groups taking part in the war will expect to be rewarded. SSR is thus crucial in the short term: if the GNA offers financial and technical expertise and resources, plus legal cover, to armed groups under its leadership, it will increase the incentive for armed groups to be receptive to its plans for reform.
  • Prevailing policy narratives presuppose that the interests of armed actors are distinct from those of the communities they claim to represent. Given the degree to which most armed groups are embedded in local society, however, successful engagement will necessarily rely on addressing the fears, grievances and desires of the surrounding communities. Yet the development of armed groups’ capacities, along with their increasing access to autonomous means of generating revenue, has steadily diluted their accountability to local communities. This process is likely to be accelerated by the ongoing violence around Tripoli.
  • Communities’ relationship to armed groups varies across different areas of the country, reflecting the social, political, economic and security environment:
  • Despite their clear preference for a more formal, state-controlled security sector, Tripoli’s residents broadly accept the need for    the presence of armed groups to provide security. The known engagement of the capital’s four main armed groups in criminal activity is a trade-off that many residents seem able to tolerate, providing that overt violence remains low. Nonetheless, there is a widespread view that the greed of Tripoli’s armed groups has played a role in stoking the current conflict.
  • In the east, many residents appear to accept (or even welcome) the LAAF’s expansion beyond the security realm, provided that it undertakes these roles effectively. That said, such is the extent of LAAF control that opposition to the alliance comes at a high price.
  • In the south, armed groups draw heavily on social legitimacy, acting as guardians of tribal zones of influence and defenders of their respective communities against outside threats, while also at times stoking local conflicts. Social protections continue to hold sway, meaning that accountability within communities is also limited.
  • To varying extents since 2014, Libya’s armed groups have developed networks that enmesh political and business stakeholders in revenue-generation models:
  • Armed groups in Tripoli have compensated for reduced financial receipts from state budgets by cultivating unofficial and illicit sources of income. They have also focused on infiltrating state institutions to ensure access to state budgets and contracts dispersed in the capital.
  • In the east of the country, the LAAF has developed a long-term strategy to dominate the security, political and economic spheres through the establishment of a quasi-legal basis for receiving funds from Libya’s rival state authorities. It has supplemented this with extensive intervention in the private sector. External patronage supports military operations, but also helps to keep this financial system, based on unsecured debt, afloat.
  • In the south, limited access to funds from the central state has spurred armed groups to become actively involved in the economy. This has translated into the taxation of movement and the imposition of protection fees, particularly on informal (and often illicit) activity.
  • Without real commitment from international policymakers to enforcing the arms embargo and protecting the economy from being weaponized, Libya will be consigned to sustained conflict, further fragmentation and potential economic collapse. Given the likely absence of a political settlement in the short term, international policymakers should seek to curtail the continued expansion of the conflict economy by reducing armed groups’ engagement in economic life.
  • In order to reduce illicit activities, international policymakers should develop their capacity to identify and target chokepoints along illicit supply chains, with a focus on restraining activities and actors in closest proximity to violence. Targeted sanctions against rent maximizers (both armed and unarmed) is likely to be the most effective strategy. More effective investigation and restraint of conflict economy actors will require systemic efforts to improve transparency and enhance the institutional capacity of anti-corruption authorities. International policymakers should also support the development of tailored alternative livelihoods that render conflict economy activities less attractive.

Evidence Against an Important Role of Plasma Insulin and Glucagon Concentrations in the Increase in EGP Caused by SGLT2 Inhibitors

Sodium–glucose cotransport 2 inhibitors (SGLT2i) lower plasma glucose but stimulate endogenous glucose production (EGP). The current study examined the effect of dapagliflozin on EGP while clamping plasma glucose, insulin, and glucagon concentrations at their fasting level. Thirty-eight patients with type 2 diabetes received an 8-h measurement of EGP ([3-3H]-glucose) on three occasions. After a 3-h tracer equilibration, subjects received 1) dapagliflozin 10 mg (n = 26) or placebo (n = 12); 2) repeat EGP measurement with the plasma glucose concentration clamped at the fasting level; and 3) repeat EGP measurement with inhibition of insulin and glucagon secretion with somatostatin infusion and replacement of basal plasma insulin and glucagon concentrations. In study 1, the change in EGP (baseline to last hour of EGP measurement) in subjects receiving dapagliflozin was 22% greater (+0.66 ± 0.11 mg/kg/min, P < 0.05) than in subjects receiving placebo, and it was associated with a significant increase in plasma glucagon and a decrease in the plasma insulin concentration compared with placebo. Under glucose clamp conditions (study 2), the change in plasma insulin and glucagon concentrations was comparable in subjects receiving dapagliflozin and placebo, yet the difference in EGP between dapagliflozin and placebo persisted (+0.71 ± 0.13 mg/kg/min, P < 0.01). Under pancreatic clamp conditions (study 3), dapagliflozin produced an initial large decrease in EGP (8% below placebo), followed by a progressive increase in EGP that was 10.6% greater than placebo during the last hour. Collectively, these results indicate that 1) the changes in plasma insulin and glucagon concentration after SGLT2i administration are secondary to the decrease in plasma glucose concentration, and 2) the dapagliflozin-induced increase in EGP cannot be explained by the increase in plasma glucagon or decrease in plasma insulin or glucose concentrations.

Tau PET imaging with 18F-PI-2620 in patients with Alzheimer's disease and healthy controls: a first-in-human study

18F-PI-2620 is a positron emission tomography (PET) tracer with high binding affinity for aggregated tau, a key pathologic feature of Alzheimer’s disease (AD) and other neurodegenerative disorders. Preclinically, 18F-PI-2620 binds to both, 3R and 4R tau isoforms. The purpose of this first-in-human study was to evaluate the ability of 18F-PI-2620 to detect tau pathology in AD patients using PET imaging, as well as to assess its safety and tolerability of this new tau PET tracer. Methods: Participants with clinical diagnosis of probable AD and healthy controls (HC) underwent dynamic 18F-PI-2620 PET imaging for 180 min. 18F-PI-2620 binding was assessed visually and quantitatively using Distribution Volume Ratios (DVR) estimated from non-invasive tracer kinetics and standardized uptake value ratios (SUVR) measured at different time points post-injection (p.i.) with the cerebellar cortex as the reference region. Time-activity curves and SUVR were assessed in AD and HC, as well as DVR and SUVR correlations and effect size (Cohen’s d) over time. Results: 18F-PI-2620 showed peak brain uptake around 5 min p.i. and fast wash-out in non-target regions. In AD subjects, focal asymmetric uptake was evident in temporal and parietal lobes, precuneus, and posterior cingulate cortex. DVR and SUVR in these regions were significantly higher in AD compared to HC. Very low background signal was observed in HC. 18F-PI-2620 administration was safe and well tolerated. SUVR time activity curves in most regions and subjects achieved a secular equilibrium after 40 min p.i.. A strong correlation (R2 > 0.93) was found between non-invasive DVR and SUVR for all imaging windows starting >30 min p.i.. Similar effect sizes between AD and HC groups were obtained across the different imaging windows. 18F-PI-2620 uptake in neocortical regions was significantly correlated with the degree of cognitive impairment. Conclusion: Initial clinical data obtained in AD and HC demonstrate the high image quality with excellent signal-to-noise of 18F-PI-2620 PET for imaging tau deposition in AD subjects. Non-invasive quantification using DVR and SUVR for 30 min imaging windows between 30-90 min p.i., e.g. 45-75 min, provides robust and significant discrimination between AD and HC subjects. 18F-PI-2620 uptake in expected regions is highly correlated to neurocognitive performance.

Clinical evaluation of a data-driven respiratory gating algorithm for whole-body positron emission tomography with continuous bed motion

Respiratory gating is the standard to overcome respiration effects degrading image quality in positron emission tomography (PET). Data-driven gating (DDG) using signals derived from PET raw data are promising alternatives to gating approaches requiring additional hardware. However, continuous bed motion (CBM) scans require dedicated DDG approaches for axially-extended PET, compared to DDG for conventional step-and-shoot scans. In this study, a CBM-capable DDG algorithm was investigated in a clinical cohort, comparing it to hardware-based gating using gated and fully motion-corrected reconstructions. Methods: 56 patients with suspected malignancies in thorax or abdomen underwent whole-body 18F-FDG CBM-PET/CT imaging using DDG and hardware-based respiratory gating (pressure-sensitive belt gating, BG). Correlation analyses were performed on both gating signals. Besides static reconstructions, BG and DDG were used for optimally-gated PET (BG-OG, DDG-OG) and fully motion-corrected PET (elastic motion correction; BG-EMOCO, DDG-EMOCO). Metabolic volumes, SUVmax and SUVmean of lesions were compared amongst the reconstructions. Additionally, the quality of lesion delineation in different PET reconstructions was independently evaluated by three experts. Results: Global correlation coefficients between BG and DDG signals amounted to 0.48±0.11, peaking at 0.89±0.07 when scanning the kidney and liver region. In total, 196 lesions were analyzed. SUV measurements were significantly higher in BG-OG, DDG-OG, BG-EMOCO and DDG-EMOCO compared to static images (P<0.001; median SUVmax: static, 14.3±13.4; BG-EMOCO, 19.8±15.7; DDG-EMOCO, 20.5±15.6; BG-OG, 19.6±17.1; DDG-OG, 18.9±16.6). No significant differences between BG-OG and DDG-OG, and BG-EMOCO and DDG-EMOCO, respectively, were found. Visual lesion delineation was significantly better in BG-EMOCO and DDG-EMOCO than in static reconstructions (P<0.001); no significant difference was found comparing BG and DDG (EMOCO, OG, respectively). Conclusion: DDG-based motion-compensation of CBM-PET acquisitions outperforms static reconstructions, delivering qualities comparable to hardware-based approaches. The new algorithm may be a valuable alternative for CBM-PET systems.

Performance of digital PET compared to high-resolution conventional PET in patients with cancer

Recently introduced PET systems using silicon photomultipliers with digital readout (dPET) have an improved timing and spatial resolution, aiming at a better image quality, over conventional PET (cPET) systems. We prospectively evaluated the performance of a dPET system in patients with cancer, as compared to high-resolution (HR) cPET imaging. Methods: After a single FDG-injection, 66 patients underwent dPET (Vereos, Philips Healthcare) and cPET (Ingenuity TF, Philips Healthcare) imaging in a randomized order. We used HR-reconstructions (2x2x2 mm3 voxels) for both scanners and determined SUVmax, SUVmean, lesion-to-background ratio (LBR), metabolic tumor volume (MTV) and lesion diameter in up to 5 FDG-positive lesions per patient. Furthermore, we counted the number of visible and measurable lesions on each PET scan. Two nuclear medicine specialists blindly determined the Tumor Node Metastasis (TNM) score from both image sets in 30 patients referred for initial staging. For all 66 patients, these specialists separately and blindly evaluated image quality (4-point scale) and determined the scan preference. Results: We included 238 lesions that were visible and measurable on both PET scans. We found 37 additional lesions on dPET in 27 patients (41%), which were unmeasurable (n = 14) or invisible (n = 23) on cPET. SUVmean, SUVmax, LBR and MTV on cPET were 5.2±3.9 (mean±SD), 6.9±5.6, 5.0±3.6 and 2991±13251 mm3, respectively. On dPET SUVmean, SUVmax and LBR increased 24%, 23% and 27%, respectively (p<0.001) while MTV decreased 13% (p<0.001) compared to cPET. Visual analysis showed TNM upstaging with dPET in 13% of the patients (4/30). dPET images also scored higher in image quality (P = 0.003) and were visually preferred in the majority of cases (65%). Conclusion: Digital PET improved the detection of small lesions, upstaged the disease and images were visually preferred as compared to high-resolution conventional PET. More studies are necessary to confirm the superior diagnostic performance of digital PET.

Digital Solid-State SPECT/CT Quantitation of Absolute 177Lu-Radiotracer Concentration: In Vivo/In Vitro Validation

The accuracy of lutetium-177 (177Lu) radiotracer concentration measurements using quantitative clinical software was determined by comparing in vivo results for a digital solid-state cadmium-zinc-telluride SPECT/CT (single photon emission computed tomography / x-ray computed tomography) system to in vitro sampling. First, image acquisition parameters were assessed for an International Electrotechnical Commission (IEC) body phantom emulating clinical count rates loaded with a "lung" insert and 6 hot spheres with a 12:1 target-to-background ratio of 177Lu solution. Then, the data of 28 whole-body SPECT/CT scans of 7 patients who underwent 177Lu prostate membrane antigen (177Lu-PSMA) radioligand therapy was retrospectively analyzed. Three users analyzed SPECT/CT images for in vivo urinary bladder radiotracer uptake using quantitative software (Q.Metrix, GE Healthcare). In vitro radiopharmaceutical concentrations were calculated using urine sampling obtained immediately after each scan, scaled to standardized uptake values (SUVs). Any in vivo/in vitro identity relations were determined by linear regression (ideally slope=1, intercept=0), within a 95 % confidence interval (CI). Phantom results demonstrated lower quantitative error for acquisitions using the 113 keV 177Lu energy peak rather than including the 208 keV peak, given that only low-energy collimation was available in this camera configuration. In the clinical study, 24 in vivo/in vitro pairs were eligible for further analysis, having rejected 4 as outliers (via Cook’s distance calculations). All linear regressions (R2 ≥ 0.92, P<0.0001) provided identity in vivo/in vitro relations (95 % CI), with SUV averages from all users giving a slope of 1.03±0.09, an intercept of –0.25±0.64 g/mL, and an average residual difference of 20.4 %. Acquiring with the lower energy 177Lu energy peak, solid-state SPECT/CT imaging provides an accuracy to within ~20 % for in vivo urinary bladder radiotracer concentrations. This non-invasive in vivo quantitation method can potentially improve diagnosis, improve patient management and treatment response assessment, and provide data essential to 177Lu dosimetry.

Confirmation of 123I-FP-CIT-SPECT (ioflupane) quantification methods in dementia with Lewy body and other neurodegenerative disorders

Rationale: To conduct a retrospective study comparing three 123I-FP-CIT-SPECT quantitative methods in patients with neurodegenerative syndromes as referenced to neuropathological findings. Methods: 123I-FP-CIT-SPECT and neuropathological findings among patients with neurodegenerative syndromes from the Mayo Alzheimer's Disease Research Center and Mayo Clinic Study of Aging were examined. Three 123I-FP-CIT-SPECT quantitative assessment Methods: MIMneuro (MIM Software Inc.), DaTQUANT (GE Healthcare), and manual region of interest (ROI) creation on an Advantage Workstation (GE Healthcare) were compared to neuropathological findings describing the presence or absence of Lewy body disease (LBD). Striatum to background ratios (SBRs) generated by DaTQUANT were compared to the calculated SBRs of the manual method and MIMneuro. The left and right SBRs for caudate, putamen and striatum were evaluated with the manual method. For DaTQUANT and MIMneuro the left, right, total and average SBRs and z-scores for whole striatum, caudate, putamen, anterior putamen, and posterior putamen were calculated. Results: The cohort included 24 patients [20 (83%) male, aged 75.4 +/- 10.0 at death]. The antemortem clinical diagnoses were Alzheimer’s disease dementia (ADem, N = 6), probable dementia with Lewy bodies (pDLB, N = 12), mixed ADem/pDLB (N = 1), Parkinson’s disease with mild cognitive impairment (N = 2), corticobasal syndrome (N = 1), idiopathic rapid eye movement sleep behavior disorder (iRBD) (N = 1) and behavioral variant frontotemporal dementia (N = 1). Seventeen (71%) had LBD pathology. All three 123I-FP-CIT-SPECT quantitative methods had area under the receiver operating characteristics (AUROC) values above 0.93 and up to 1.000 (p<0.001) and showed excellent discrimination between LBD and non-LBD patients in each region assessed, p<.001. There was no significant difference between the accuracy of the regions in discriminating the two groups, with good discrimination for both caudate and putamen. Conclusion: All three 123I-FP-CIT-SPECT quantitative methods showed excellent discrimination between LBD and non-LBD patients in each region assessed, using both SBRs and z-scores.

The effects of monosodium glutamate on PSMA radiotracer uptake in men with recurrent prostate cancer: a prospective, randomized, double-blind, placebo-controlled intra-individual imaging study.

The prostate-specific membrane antigen (PSMA) is an excellent target for theranostic applications in prostate cancer (PCa). However, PSMA-targeted radioligand therapy can cause undesirable effects due to high accumulation of PSMA radiotracers in salivary glands and kidneys. This study assessed orally administered monosodium glutamate (MSG) as a potential means of reducing kidney and salivary gland radiation exposure using a PSMA targeting radiotracer. Methods: This prospective, double-blind, placebo-controlled study enrolled 10 biochemically recurrent PCa patients. Each subject served as his own control. [18F]DCFPyl PET/CT imaging sessions were performed 3 – 7 days apart, following oral administration of either 12.7 g of MSG or placebo. Data from the two sets of images were analyzed by placing regions of interest on lacrimal, parotid and submandibular glands, left ventricle, liver, spleen, kidneys, bowel, urinary bladder, gluteus muscle and malignant lesions. The results from MSG and placebo scans were compared by paired analysis of the ROI data. Results: A total of 142 pathological lesions along with normal tissues were analyzed. As hypothesized a priori, there was a significant decrease in maximal standardized uptake values corrected for lean body mass (SULmax) on images obtained following MSG administration in the parotids (24 ± 14%, P = 0.001), submandibular glands (35 ± 11%, P<0.001) and kidneys (23 ± 26%, P = 0.014). Significant decreases were also observed in lacrimal glands (49 ± 13%, P<0.001), liver (15 ± 6%, P<0.001), spleen (28 ± 13%, P = 0.001) and bowel (44 ± 13%, P<0.001). Mildly lower blood pool SULmean was observed after MSG administration (decrease of 11 ± 13%, P = 0.021). However, significantly lower radiotracer uptake in terms of SULmean, SULpeak, and SULmax was observed in malignant lesions on scans performed after MSG administration compared to the placebo studies (SULmax median decrease 33%, range -1 to 75%, P<0.001). No significant adverse events occurred and vital signs were stable following placebo or MSG administration. Conclusion: Orally administered MSG significantly decreased salivary gland, kidney and other normal organ PSMA radiotracer uptake in human subjects, using [18F]DCFPyL as an exemplar. However, MSG caused a corresponding reduction in tumor uptake, which may limit the benefits of this approach for diagnostic and therapeutic applications.

Three private roundtable meetings were convened in the first quarter of 2019, with the aim of generating informed and constructive new thinking on policy options and reforms that could help Sudan build a more economically prosperous, stable and inclusive nation. The roundtables were held under the Chatham House Rule.

The project sought to offer a neutral space for discussion to policymakers and influencers from a broad range of backgrounds: Sudanese government officials, opposition figures, economists, experts on Sudan’s political economy and governance, civil society figures, representatives of international financial institutions, and other international policymakers.

This paper draws together the key themes and findings from each of the three roundtables, ranging from broad structural economic issues to sector-specific priority interventions. It presents options and recommendations for Sudanese leaders, including the transitional government, in support of building a more economically prosperous, peaceful and inclusive nation.

Event participants

Hon Guillaume Soro, Chairman, Rassemblement Pour la Côte d’Ivoire (RACI)
Chair: Paul Melly, Consulting Fellow, Africa Programme, Chatham House

As Côte d'Ivoire enters a critical final 12 months before presidential elections scheduled for October 2020, the political atmosphere remains highly uncertain, stoked by the fracturing of the RDR-PDCI alliance and the potential candidacy of a range of high-profile political names. While President Ouattara’s two terms in office have ushered in an improved business environment, with annual economic growth averaging 8 per cent since 2012, political instability over the next 12 months may pose a threat to recent progress and raises wider security concerns in light of the major post-election violence witnessed a decade previously.

At this event, Ivorian presidential contender, and former prime minister and parliamentary speaker, Guillaume Soro, will assess the prime-election context in Côte d'Ivoire and the policies required to deliver inclusive growth and future stability for its citizens.

Attendance at this event is by invitation only.

China's ivory bans: enhancing soft power through wildlife conservation

6 November 2019 , Volume 95, Number 6

Jonas Gamso

China has been a major market for elephant ivory for centuries. However, the Chinese government recently enacted bans on imports and exports of ivory (2015) and on the domestic ivory trade (2017). These bans appear to have come in response to intensive influence campaigns and public shaming from domestic and foreign activists, who cited declining elephant populations and highlighted China's role. However, this shaming-narrative is at odds with conventional wisdom regarding Chinese policy-making: China typically resists international pressures and its authoritarian government is thought to be largely insulated from domestic efforts by civil society groups. This article reconciles Beijing's ivory policy with these conventional beliefs about policy-making in China. I argue that the Chinese government saw unique benefits to banning the ivory trade, under growing international scrutiny, as doing so enhanced Chinese soft power while having very little impact on its sovereignty or development. Non-government organizations (NGOs) operating both inside and outside of China played a role as well: NGOs in China helped to shift Chinese public opinion towards favouring the bans, while those operating abroad led public relations efforts to publicize Chinese demand for ivory to foreign audiences. Efforts by the latter group of NGOs intensified pressure on the Chinese government to rein in the ivory market, while increasing the soft power benefits that banning ivory would bring to Beijing.

POSTPONED: Connecting Infrastructure Development and Inclusive Economic Growth in Côte d'Ivoire

Research Event

13 March 2020 - 4:00pm to 5:00pm

Chatham House | 10 St James's Square | London | SW1Y 4LE

Event participants

Hon Bruno Nabagné Kone, Minister of Construction, Housing and Urban Planning, Republic of Côte d'Ivoire

Strong economic growth in Côte d'Ivoire – with annual GDP growth averaging eight per cent since 2012 – is interlinked with an increase in spending on national infrastructure. In 2018, the government announced a $7 billion injection for the sector over five years, for projects including a new 7.5km bridge spanning two districts of Abidjan and a highway extending to Burkina Faso. A public-private partnership to build a new $1.5 billion metropolitan railway system in the capital received formal approval in October 2019.

But the government of Côte d'Ivoire has struggled to make the country’s impressive growth inclusive: Côte d’Ivoire ranked 165th out of 189 on the 2019 United Nations Human Development Index, and the poverty rate is around 46%. Translating significant infrastructural investment into benefit for ordinary and vulnerable Ivorian citizens, including through how project development is managed with communities, will be a critical issue in the lead up to elections scheduled for October 2020 and beyond.

Economic Recovery and Anticorruption in South Africa: Assessing Progress on the Reform Agenda

Invitation Only Research Event

4 December 2019 - 3:00pm to 4:00pm

Chatham House | 10 St James's Square | London | SW1Y 4LE

Event participants

Professor Nick Binedell, Founding Director and Sasol Chair of Strategic Management, Gordon Institute of Business Science (GIBS), University of Pretoria

South Africa has significant economic potential based on its resource endowment, quality human capital and well-developed infrastructure compared to the region. However, the country’s economic growth rate has not topped 2 per cent since 2013, and in 2018, was below 1 per cent. This has put a strain on citizens and communities in a country that still suffers from structural inequality, poverty and high unemployment. Economic recovery and anti-corruption were the central pillars of President Cyril Ramaphosa’s 2019 electoral campaign and he has set an investment target of $100 billion. However, voters and investors alike are demanding faster and more visible progress from the country’s enigmatic leader who has a reputation for caution and calculation.

At this event, Professor Nick Binedell will discuss the progress of and opposition to the president’s economic reform agenda and the opportunities for international investment to support long term inclusive and sustainable growth in South Africa.

Attendance at this event is by invitation only.

The African Continental Free Trade Area Could Boost African Agency in International Trade

10 December 2019

Assistant Director, Africa Programme

Director, Trade and Industry, African Union Commission (2012–19)
The agreement, which entered into force in May, could be a major step for Africa’s role in international trade, if the continent can overcome barriers to implementation.

The entry into force of the African Continental Free Trade Area (AfCFTA) on 30 May, after only three years of negotiations, is an economic, political and diplomatic milestone for the African Union (AU) and its member states, crucial for economic growth, job creation, and making Africa a meaningful player in international trade. But the continent will have to work together to ensure that the potential benefits are fully realized.

A necessary innovation

With its advances in maintaining peace and security, abundant natural resources, high growth rates, improved linkages to global supply chains and a youthful population, Africa is emerging as a new global centre of economic growth, increasingly sought after as a partner by the world’s biggest economies. Governments from across Africa have been taking a more assertive role in international markets, including through proactive diversification of trading partners, and the continent remains a strong advocate for the multilateral trading system.

However, this is not yet reflected in outcomes. The African Union does not have observer status at the World Trade Organization, despite diplomatic efforts in the past decade. Africa has less than a three per cent share of global trade, and the growing trend towards protectionism across the global economy may only increase the vulnerability of a disunited Africa. Its fractured internal market means that trade within Africa is lower than for any other region on the globe, with intra-African trade just 18 per cent of overall exports, as compared to 70 per cent in Europe.

The AfCFTA is the continent’s tool to address the disparity between Africa’s growing economic significance and its peripheral place in the global trade system, to build a bridge between present fragmentation and future prosperity. It is an ambitious, comprehensive agreement covering trade in goods, services, investment, intellectual property rights and competition policy. It has been signed by all of Africa’s states with the exception of Eritrea.

It is the AU's Agenda 2063 flagship project, brought about by the decisions taken at the January 2012 African Union Summit to boost intra-African trade and to fast track the establishment of the Continental Free Trade Area. It builds upon ambitions enshrined in successive agreements including the Lagos Plan of Action and the Abuja Treaty. Access to new regional markets and reduced non-tariff barriers are intended to help companies scale up, driving job creation and poverty reduction, as well as attracting inward investment to even Africa’s smaller economies.

The signing in 2018 of the instruments governing the Single Air Transport Market and the Protocol on Free Movement of Persons, Right of Residence and Right of Establishment provided another step towards the gradual elimination of barriers to the movement of goods, services and people within the continent.

Tests to come

However, while progress is being made towards the ratification of the AfCFTA, much remains to be done before African countries can fully trade under its terms. The framework for implementation is still under development, and the creation of enabling infrastructure that is critical for connectivity will take time to develop and requires extensive investment.

Africa’s Future in a Changing Global Order: Africa’s Economic Diplomacy

Treasure Thembisile Maphanga talks about the international implications of the African Continental Free Trade Agreement (AfCFTA).

So, the first test for the AfCFTA will be the level to which Africa’s leaders make it a domestic priority, and whether a consensus can be maintained across the AU’s member states as the costs of implementation become clear.

There is no guarantee that the gains of free trade will be evenly distributed. They will mainly depend on the extent to which countries embrace industrialization, liberalization of their markets and opening of their borders for free movement of goods and people – policies that some incumbent leaders may be reluctant to implement. Political will to maintain a unified negotiating position with diverse stakeholders, including the private sector, will come under increasing stress.  

A second challenge is how the AfCFTA relates to already existing trade arrangements, notably with the EU.  The AU has long preferred to pursue a continent-to-continent trading arrangement instead of the bilateral Economic Partnership Agreements being sought by the EU under the African, Caribbean and Pacific (ACP) framework to which, with the exception of Algeria, Egypt, Libya, Morocco, Tunisia and South Africa, all African states belong. The signing of the AfCFTA is one important step towards making this possible.

But there are currently negotiations under the ACP to replace the Cotonou Accord (the framework governing trade between ACP members and the EU, including Economic Partnership Agreements [EPAs], that is due to expire in 2020). Negotiations on the African pillar of the accord are due to take place after the AfCFTA has entered into force. So African states and the AU will face the challenge of balancing their commitment to the ACP bloc with pursuing their own interests.

And though the AfCFTA should supersede any other agreements, the EPAs or their successors, will continue to govern day-to-day trading, in parallel to the new pan-African market. It is not yet clear how these contradictions will be reconciled.

A new role for the AU?

The AU will need to play an active role as the main interlocutor with Africa´s international trading partners, with the AfCFTA secretariat being the arbiter of internal tensions and trade disputes. The AU´s engagement at continental level has to date revolved mainly around headline political diplomacy, security and peacekeeping. With the continental free market becoming a reality, an effective pivot to economic diplomacy will be critical for growth and development.

With the AfCFTA, the AU has endeavoured to address Africa’s unsustainable position in global trade, to stimulate growth, economic diversification and jobs for its growing population. Much will depend on the commitment of African leaders to maintaining a unified negotiating position to implement the agreement and the AU’s capacity to effectively move from political to economic diplomacy.

Chatham House | 10 St James's Square | London | SW1Y 4LE

Event participants

Raj Kulasingam, Senior Counsel, Dentons

Megan McDonald, Head of Investment Banking (International), Standard Bank Group

Chair: Dr Alex Vines OBE, Managing Director, Ethics, Risk & Resilience; Director, Africa Programme, Chatham House

Theresa May’s announcement in 2018 on the UK’s ambition to become the G7’s largest investor in Africa by 2022 has been followed by similar stated ambitions at the recent UK-Africa Investment Summit, which saw the attendance of 16 African heads of states. Such ambitions mirror overtures from various international players including a call for a ‘comprehensive strategy for Africa’ by the EU in 2019. While the UK’s recent expansion of its diplomatic networks in Africa and the signing of the Economic Partnership Agreement with the Southern African Customs Union and Mozambique appear promising, there are significant challenges to deepening partnerships including visa restrictions and complex business environments.
 
At this event, the panellists will assess the future of trade and investment relations between the UK and Africa. Amid a proliferation of new trading partners including Asia’s emerging economies, Russia and the Gulf states, what are the points of change and continuity in the long-standing relationship between Africa and the UK? And what are the challenges and opportunities facing governments and businesses in Africa and the UK in efforts to build long-lasting economic ties?
 
This event will be followed by a drinks reception.

This event is open to Chatham House Corporate Members and corporate contacts of Chatham House's Africa Programme only.

POSTPONED: Pursuing Economic Reform and Growth in South Africa: the view from the African National Congress

Research Event

18 March 2020 - 10:30am to 11:30am

Chatham House | 10 St James's Square | London | SW1Y 4LE

Event participants

Paul Mashatile, Treasurer General, African National Congress (ANC)

The government of South Africa is pursuing a programme of reform to revitalize the economy, strengthen institutions and combat corruption. The State of the Nation Address (SONA) on 13 February and the budget speech of 26 February represent the most significant articulation of the government’s economic strategy. Central to this is the government’s plans for the energy sector, which is fundamental for reviving the economy, and the reform of State Owned Enterprises (SOEs). But questions remain about possible divergence of the approach taken by government ministers from the policy position of the ruling party, the African National Congress (ANC), and what this might mean for the sustainability and progress of reform.  

At this event, Paul Mashatile, Treasurer General of the ANC, will discuss the party’s assessment of reform efforts to date and priorities for delivering on inclusive growth.

Webinar: Implications of the COVID-19 Pandemic for African Economies and Development

Research Event

21 April 2020 - 4:30pm to 5:30pm

Event participants

Dr Hafez Ghanem, Vice President for Africa, World Bank
Chair: Elizabeth Donnelly, Deputy Director, Africa Programme, Chatham House

Dr Hafez Ghanem discusses the implications of the COVID-19 pandemic for African economies and their development and poverty reduction efforts, and assesses the priorities and obstacles for establishing a comprehensive response to the crisis.
 
While the acute strain placed on health systems by the COVID-19 pandemic is already in evidence, the long-term economic fallout from the crisis is yet to fully manifest.
 
For Africa it is the economic impact that may leave the most enduring legacy: from the direct expense of measures to treat, detect and reduce the spread of the virus; to the indirect costs of domestic lockdown measures, global supply chain disruptions and plummeting commodity prices.
 
As decision-makers globally start to plan for the scale of this economic shock, strategizing in and on Africa to meet the challenge will require unprecedented planning and commitment - and will need to be matched by support from international partners to enable long-term recovery.

Add to Calendar
Natasha Kimani, Academy Associate, Chatham House; Head of Partnerships and Programmes, Shujaaz Inc.
Chair: Tighisti Amare, Assistant Director, Africa Programme, Chatham House
While gender equality was enshrined in Kenyan law under the 2010 constitution, gender-based marginalization remains a significant issue across all levels of society. The advent of devolution in 2013 raised hopes of enhanced gender awareness in policymaking and budgeting, with the 47 newly instituted county governments expected to tackle the dynamics of inequality close to home, but implementation has so far failed to match this initial promise. As Kenya approaches the tenth anniversary of the constitution, and with the COVID-19 pandemic throwing the challenges of gender inequality into sharper relief, it is critical to ensure that constitutional pathways are followed with the requisite level of urgency, commitment and investment to address entrenched gender issues.
 
This event, which will launch the report, Meeting the Promise of the 2010 Constitution: Devolution, Gender and Equality in Kenya, will assess the current status of efforts to devolve and adopt gender-responsive budgeting and decision-making in Kenya, and the priorities and potential future avenues to tackle the implementation gap.

Upregulation of CD73 Confers Acquired Radioresistance and is Required for Maintaining Irradiation-selected Pancreatic Cancer Cells in a Mesenchymal State [Research]

The molecular mechanisms underlying exceptional radioresistance in pancreatic cancer remain elusive. In the present study, we established a stable radioresistant pancreatic cancer cell line MIA PaCa-2-R by exposing the parental MIA PaCa-2 cells to fractionated ionizing radiation (IR). Systematic proteomics and bioinformatics analysis of protein expression in MIA PaCa-2 and MIA PaCa-2-R cells revealed that several growth factor-/cytokine-mediated pathways, including the OSM/STAT3, PI3K/AKT, and MAPK/ERK pathways, were activated in the radioresistant cells, leading to inhibition of apoptosis and increased epithelial-mesenchymal plasticity. In addition, the radioresistant cells exhibited enhanced capabilities of DNA repair and antioxidant defense compared with the parental cells. We focused functional analysis on one of the most up-regulated proteins in the radioresistant cells, ecto-5'-nucleotidase (CD73), which is a cell surface protein that is overexpressed in different types of cancer. Ectopic overexpression of CD73 in the parental cells resulted in radioresistance and conferred resistance to IR-induced apoptosis. Knockdown of CD73 re-sensitized the radioresistant cells to IR and IR-induced apoptosis. The effect of CD73 on radioresistance and apoptosis is independent of the enzymatic activity of CD73. Further studies demonstrate that CD73 up-regulation promotes Ser-136 phosphorylation of the proapoptotic protein BAD and is required for maintaining the radioresistant cells in a mesenchymal state. Our findings suggest that expression alterations in the IR-selected pancreatic cancer cells result in hyperactivation of the growth factor/cytokine signaling that promotes epithelial-mesenchymal plasticity and enhancement of DNA repair. Our results also suggest that CD73, potentially a novel downstream factor of the enhanced growth factor/cytokine signaling, confers acquired radioresistance by inactivating proapoptotic protein BAD via phosphorylation of BAD at Ser-136 and by maintaining the radioresistant pancreatic cancer cells in a mesenchymal state.

Molecular Basis of the Mechanisms Controlling MASTL [Research]

The human MASTL (Microtubule-associated serine/threonine kinase-like) gene encodes an essential protein in the cell cycle. MASTL is a key factor preventing early dephosphorylation of M-phase targets of Cdk1/CycB. Little is known about the mechanism of MASTL activation and regulation. MASTL contains a non-conserved insertion of 550 residues within its activation loop, splitting the kinase domain, and making it unique. Here, we show that this non-conserved middle region (NCMR) of the protein is crucial for target specificity and activity. We performed a phosphoproteomic assay with different MASTL constructs identifying key phosphorylation sites for its activation and determining whether they arise from autophosphorylation or exogenous kinases, thus generating an activation model. Hydrogen/deuterium exchange data complements this analysis revealing that the C-lobe in full-length MASTL forms a stable structure, whereas the N-lobe is dynamic and the NCMR and C-tail contain few localized regions with higher-order structure. Our results indicate that truncated versions of MASTL conserving a cryptic C-Lobe in the NCMR, display catalytic activity and different targets, thus establishing a possible link with truncated mutations observed in cancer-related databases.

Concentration Determination of >200 Proteins in Dried Blood Spots for Biomarker Discovery and Validation [Technological Innovation and Resources]

The use of protein biomarkers as surrogates for clinical endpoints requires extensive multilevel validation including development of robust and sensitive assays for precise measurement of protein concentration. Multiple reaction monitoring (MRM) is a well-established mass-spectrometric method that can be used for reproducible protein-concentration measurements in biological specimens collected via microsampling. The dried blood spot (DBS) microsampling technique can be performed non-invasively without the expertise of a phlebotomist, and can enhance analyte stability which facilitate the application of this technique in retrospective studies while providing lower storage and shipping costs, because cold-chain logistics can be eliminated. Thus, precise, sensitive, and multiplexed methods for measuring protein concentrations in DBSs can be used for de novo biomarker discovery and for biomarker quantification or verification experiments. To achieve this goal, MRM assays were developed for multiplexed concentration measurement of proteins in DBSs.

The lower limit of quantification (LLOQ) was found to have a median total coefficient of variation (CV) of 18% for 245 proteins, whereas the median LLOQ was 5 fmol of peptide injected on column, and the median inter-day CV over 4 days for measuring endogenous protein concentration was 8%. The majority (88%) of the assays displayed parallelism, whereas the peptide standards remained stable throughout the assay workflow and after exposure to multiple freeze-thaw cycles. For 190 proteins, the measured protein concentrations remained stable in DBS stored at ambient laboratory temperature for up to 2 months. Finally, the developed assays were used to measure the concentration ranges for 200 proteins in twenty same sex, same race and age matched individuals.

Identification of an Unconventional Subpeptidome Bound to the Behcet's Disease-associated HLA-B*51:01 that is Regulated by Endoplasmic Reticulum Aminopeptidase 1 (ERAP1) [Research]

Human leukocyte antigen (HLA) B*51:01 and endoplasmic reticulum aminopeptidase 1 (ERAP1) are strongly genetically associated with Behcet's disease (BD). Previous studies have defined two subgroups of HLA-B*51 peptidome containing proline (Pro) or alanine (Ala) at position 2 (P2). Little is known about the unconventional non-Pro/Ala2 HLA-B*51-bound peptides. We aimed to study the features of this novel subpeptidome, and investigate its regulation by ERAP1. CRISPR-Cas9 was used to generate an HLA-ABC-triple knockout HeLa cell line (HeLa.ABC-KO), which was subsequently transduced to express HLA-B*51:01 (HeLa.ABC-KO.B51). ERAP1 was silenced using lentiviral shRNA. Peptides bound to HLA-B*51:01 were eluted and analyzed by mass spectrometry. The characteristics of non-Pro/Ala2, Pro2, and Ala2 peptides and their alteration by ERAP1 silencing were investigated. Effects of ERAP1 silencing on cell surface expression of HLA-B*51:01 were studied using flow cytometry. More than 20% of peptides eluted from HLA-B*51:01 lacked Pro or Ala at P2. This unconventional group of HLA-B*51:01-bound peptides was relatively enriched for 8-mers (with relatively fewer 9-mers) compared with the Pro2 and Ala2 subpeptidomes and had similar N-terminal and C-terminal residue usages to Ala2 peptides (with the exception of the less abundant leucine at position ). Knockdown of ERAP1 increased the percentage of non-Pro/Ala2 from 20% to ~40%, increased the percentage of longer (10-mer and 11-mer) peptides eluted from HLA-B*51:01 complexes, and abrogated the predominance of leucine at P1. Interestingly knockdown of ERAP1 altered the length and N-terminal residue usage of non-Ala2&Pro2 and Ala2 but not the Pro2 peptides. Finally, ERAP1 silencing regulated the expression levels of cell surface HLA-B*51 in a cell-type-dependent manner. In conclusion, we have used a novel methodology to identify an unconventional but surprisingly abundant non-Pro/Ala2 HLA-B*51:01 subpeptidome. It is increased by knockdown of ERAP1, a gene affecting the risk of developing BD. This has implications for theories of disease pathogenesis.

The mitochondrial protein PGAM5 suppresses energy consumption in brown adipocytes by repressing expression of uncoupling protein 1 [Metabolism]

Accumulating evidence suggests that brown adipose tissue (BAT) is a potential therapeutic target for managing obesity and related diseases. PGAM family member 5, mitochondrial serine/threonine protein phosphatase (PGAM5), is a protein phosphatase that resides in the mitochondria and regulates many biological processes, including cell death, mitophagy, and immune responses. Because BAT is a mitochondria-rich tissue, we have hypothesized that PGAM5 has a physiological function in BAT. We previously reported that PGAM5-knockout (KO) mice are resistant to severe metabolic stress. Importantly, lipid accumulation is suppressed in PGAM5-KO BAT, even under unstressed conditions, raising the possibility that PGAM5 deficiency stimulates lipid consumption. However, the mechanism underlying this observation is undetermined. Here, using an array of biochemical approaches, including quantitative RT-PCR, immunoblotting, and oxygen consumption assays, we show that PGAM5 negatively regulates energy expenditure in brown adipocytes. We found that PGAM5-KO brown adipocytes have an enhanced oxygen consumption rate and increased expression of uncoupling protein 1 (UCP1), a protein that increases energy consumption in the mitochondria. Mechanistically, we found that PGAM5 phosphatase activity and intramembrane cleavage are required for suppression of UCP1 activity. Furthermore, utilizing a genome-wide siRNA screen in HeLa cells to search for regulators of PGAM5 cleavage, we identified a set of candidate genes, including phosphatidylserine decarboxylase (PISD), which catalyzes the formation of phosphatidylethanolamine at the mitochondrial membrane. Taken together, these results indicate that PGAM5 suppresses mitochondrial energy expenditure by down-regulating UCP1 expression in brown adipocytes and that its phosphatase activity and intramembrane cleavage are required for UCP1 suppression.
