si Persuasion or manipulation? Limiting campaigning online By www.chathamhouse.org Published On :: Mon, 15 Feb 2021 17:30:23 +0000 Persuasion or manipulation? Limiting campaigning online Expert comment NCapeling 15 February 2021 To tackle online disinformation and manipulation effectively, regulators must clarify the dividing line between legitimate and illegitimate campaign practices. Democracy is at risk, not only from disinformation but from systemic manipulation of public debate online. Evidence shows social media drives control of narratives, polarization, and division on issues of politics and identity. We are now seeing regulators turn their attention to protecting democracy from disinformation and manipulation. But how should they distinguish between legitimate and illegitimate online information practices, between persuasive and manipulative campaigning? Unregulated, the tactics of disinformation and manipulation have spread far and wide. They are no longer the preserve merely of disaffected individuals, hostile international actors, and authoritarian regimes. Facebook’s periodic reporting on coordinated inauthentic behaviour and Twitter’s on foreign information operations reveal that militaries, governments, and political campaigners in a wide range of countries, including parts of Europe and America, have engaged in manipulative or deceptive information campaigns. For example, in September 2019, Twitter removed 259 accounts it says were ‘falsely boosting’ public sentiment online that it found to be operated by Spain’s conservative and Christian-democratic political party Partido Popular. In October 2020, Facebook removed accounts with around 400,000 followers linked to Rally Forge, a US marketing firm which Facebook claims was working on behalf of right-wing organisations Turning Point USA and Inclusive Conservation Group. And in December 2020, Facebook took down a network of accounts with more than 6,000 followers, targeting audiences in Francophone Africa and focusing on France’s policies there, finding it linked with individuals associated with the French military. Public influence on a global scale Even more revealingly, in its 2020 Global Inventory of Organized Social Media Manipulation, the Oxford Internet Institute (OII) found that in 81 countries, government agencies and/or political parties are using ‘computational propaganda’ in social media to shape public attitudes. These 81 countries span the world and include not only authoritarian and less democratic regimes but also developed democracies such as many EU member states. OII found that countries with the largest capacity for computational propaganda – which include the UK, US, and Australia – have permanent teams devoted to shaping the online space overseas and at home. OII categorizes computational propaganda as four types of communication strategy – the creation of disinformation or manipulated content such as doctored images and videos; the use of personal data to target specific segments of the population with disinformation or other false narratives; trolling, doxing or online harassment of political opponents, activists or journalists; and mass-reporting of content or accounts posted or run by opponents as part of gaming the platforms’ automated flagging, demotion, and take-down systems. Doubtless some of the governments included within OII’s statistics argue their behaviour is legitimate and appropriate, either to disseminate information important to the public interest or to wrestle control of the narrative away from hostile actors. Similarly, no doubt some political campaigners removed by the platforms for alleged engagement in ‘inauthentic behaviour’ or ‘manipulation’ would defend the legitimacy of their conduct. The fact is that clear limits of acceptable propaganda and information influence operations online do not exist. Platforms still share little information overall about what information operations they see being conducted online. Applicable legal principles such as international human rights law have not yet crystallised into clear rules. As information operations are rarely exposed to public view – with notable exceptions such as the Cambridge Analytica scandal – there is relatively little constraint in media and public scrutiny or censure. OII’s annual reports and the platforms’ periodic reports demonstrate a continual expansion of deceptive and manipulative practices since 2016, and increasing involvement of private commercial companies in their deployment. Given the power of political influence as a driver, this absence of clear limits may result in ever more sophisticated techniques being deployed in the search for maximal influence. Ambiguity over reasonable limits on manipulation plays into the hands of governments which regulate ostensibly in the name of combating disinformation, but actually in the interests of maintaining their own control of the narrative and in disregard of the human right to freedom of expression. Following Singapore’s 2019 prohibition of online untruths, 17 governments ranging from Bolivia to Vietnam to Hungary passed regulations during 2020 criminalising ‘fake news’ on COVID-19 while many other governments are alleged to censor opposition arguments or criticisms of official state narratives. Clear limits are needed. Facebook itself has been calling for societal discussion about the limits of acceptable online behaviour for some time and has issued recommendations of its own. The European Democracy Action Plan: Aiming to protect pluralism and vigour in democracy The European Democracy Action Plan (EDAP), which complements the European Commission’s Digital Services Act and Digital Markets Act proposals, is a welcome step. It is ground-breaking in its efforts to protect the pluralism and vigour of European democracies by tackling all forms of online manipulation, while respecting human rights. While the EDAP tackles disinformation, it also condemns two categories of online manipulation – information influence operations which EDAP describes as ‘coordinated efforts by either domestic or foreign actors to influence a target audience using a range of deceptive means’ and foreign interference, described as ‘coercive and deceptive efforts to disrupt the free formation and expression of individuals’ political will by a foreign state actor or its agents’. These categories include influence operations such as harnessing fake accounts or gaming algorithms, and the suppression of independent information sources through censorship or mass reporting. But the categories are so broad they risk capturing disinformation practices not only of rogue actors, but also of governments and political campaigners both outside and within the EU. The European Commission plans to work towards refined definitions. Its discussions with member states and other stakeholders should start to determine which practices ought to be tackled as manipulative, and which ought to be tolerated as legitimate campaigning or public information practices. Subscribe to our emails To receive the latest content and events on the areas that interest you. Enter email address Subscribe The extent of the EDAP proposals on disinformation demonstrates the EU’s determination to tackle online manipulation. The EDAP calls for improved practical measures building on the Commission’s 2020 acceleration of effort in the face of COVID-19 disinformation. The Commission is considering how best to impose costs on perpetrators of disinformation, such as by disrupting financial incentives or even imposing sanctions for repeated offences. Beyond the regulatory and risk management framework proposed by the Digital Services Act (DSA), the Commission says it will issue guidance for platforms and other stakeholders to strengthen their measures against disinformation, building on the existing EU Code of Practice on Disinformation and eventually leading to a strengthened Code with more robust monitoring requirements. These are elements of a broader package of measures in the EDAP to preserve democracy in Europe. Until there are clear limits, manipulative practices will continue to develop and to spread. More actors will resort to them in order not to be outgunned by opponents. It is hoped forthcoming European discussions – involving EU member state governments, the European Parliament, civil society, academia and the online platforms – will begin to shape at least a European and maybe a global consensus on the limits of information influence, publicly condemning unacceptable practices while safeguarding freedom of expression. Most importantly, following the example of the EDAP, the preservation of democracy and human rights – rather than the promotion of political or commercial interest – should be the lodestar for those discussions.

si The regional and international implications of restrictions to online freedom of expression in Asia By www.chathamhouse.org Published On :: Fri, 12 Mar 2021 12:25:49 +0000 The regional and international implications of restrictions to online freedom of expression in Asia 25 March 2021 — 12:30PM TO 1:30PM Anonymous (not verified) 12 March 2021 Online Panellists discuss the latest developments affecting online freedom of expression in the Asia region. Please note this is an online event. Please register using the link below to finalize your registration. In recent years, state-led clampdowns on online freedom of expression have become widespread in several countries across Asia, further intensified by the COVID-19 crisis. The reasons for this are complex and diverse – drawing upon history, culture and politics, in addition to external influences. Across the region, governments have been accused of silencing online criticism and failing to uphold rights to free speech. Individuals have been arrested, fined or attacked for the alleged spread of ‘fake news’, raising concern among human rights organizations. In some countries, this has culminated in the imposition of new social media rules, which could require social media companies to censor posts and share decrypted messages. In China, the government’s restrictive online regime has relied on a combination of legal, technical and manipulation tactics to manage control of the internet, and now includes attempts at censorship beyond its borders. Panellists will discuss the latest regional developments affecting online freedom of expression in the Asia region, and will consider the broader regional and international implications for technology governance. This webinar launches the publication Restrictions on online freedom of expression in China: The domestic, regional and international implications of China’s policies and practices. Full Article
si Battle lines being drawn over online freedoms in Asia By www.chathamhouse.org Published On :: Mon, 22 Mar 2021 17:52:57 +0000 Battle lines being drawn over online freedoms in Asia Expert comment NCapeling 22 March 2021 Social media giants are increasingly clashing with Asian governments over free expression and censorship as the region lurches towards digital authoritarianism. Freedom of expression was subject to significant restrictions in Asia even before the pandemic, with several governments having enacted laws that stifle online debate. But since COVID-19, restrictions have increased even further due to a rash of so-called ‘emergency measures’ introduced by governments across the region. Bangladesh, India, Indonesia, Malaysia, Myanmar, Nepal, Pakistan, the Philippines, Sri Lanka, Thailand, and Vietnam have all put new laws into place, and many restrictions are already being applied in a draconian fashion, such as in the Philippines and Bangladesh. As outlined in a new Chatham House research paper, one inspiration behind this trend is China, home to the world’s most sophisticated and restrictive system of internet control. The Chinese government’s restrictive online regime, which has tightened further under COVID-19, relies on a combination of legal regulations, technical controls, and proactive manipulation of online debates. The Chinese government is exporting both its technology – such as through the establishment of smart cities, the installation of AI, and surveillance technology – and its vision of how the internet should be governed This model was an inspiration for Vietnam’s cybersecurity law, as well as Myanmar’s new draft cybersecurity bill, proposed by the Military-run State Administration Council in the wake of the military coup last month, which would give the military there extensive powers to access individuals’ data, restrict, or suspend access to the internet. This ‘sovereignty and control’ model of internet governance is also gaining impetus through China’s ‘Digital Silk Road’ initiative, under which the Chinese government is exporting both its technology – such as through the establishment of smart cities, the installation of AI, and surveillance technology – and its vision of how the internet should be governed. In November 2020, Xi Jinping pledged to further deepen cooperation with ASEAN through the Digital Silk Road, and the pandemic has expanded the appeal of Chinese surveillance technologies and data collection platforms to governments both in Asia and beyond. China’s Health Silk Road, which aims to promote global health cooperation, is centered on the Chinese government’s high-tech model under which civic freedoms are sacrificed in the name of public health. An alternative model This ‘sovereignty and control’ model is increasingly at odds with the more ‘human-centric’ model of tech governance favoured by many democratic states, Western social media companies, and international institutions, especially the United Nations (UN) and European Union (EU). Although this emerging model also involves regulation, it is regulation which aims to be inclusive, risk-based, and proportionate – balancing the need for protection against online harms with the need to preserve freedom of expression. It is a multi-stakeholder, rights-based approach which brings together not just governments but also representatives of the private sector, civil society, and academia. The EU’s draft Digital Services Act and the UK’s proposals for an Online Safety Bill are both reflective of this approach. Western social media giants such as Facebook and Twitter have recently introduced new policies which seek to identify and mitigate online harms, such as hate speech and disinformation. Industry bodies such as the Global Network Initiative, independent oversight bodies such as the Oversight Board established by Facebook, and civil society advocacy and initiatives such as the Santa Clara Principles on Transparency and Accountability in Content Moderation are also an important part of the picture. This ‘sovereignty and control’ model is increasingly at odds with the more ‘human-centric’ model of tech governance favoured by many democratic states, Western social media companies, and international institutions Admittedly, these various digital governance initiatives are in some cases embryonic, and are by no means a silver bullet solution to the complex problem of online content moderation, which continues to be hotly debated in democratic societies. But they are at least underpinned by the same philosophy – that international human rights law standards must continue to apply even during emergencies such as COVID-19. With the Biden administration in the US prioritizing tech governance in its policy agenda, there is added momentum to the international leadership behind this model. A clash of ideology These conflicting philosophies are playing out in debates on technology governance at the UN, with one group of countries led by China and Russia advocating for greater government control of the internet, and many Western democracies emphasizing the need for an open, global internet that protects human rights. These differing ideologies are also creating tensions between Western social media companies operating in Asia and the various governments in that region which have increased restrictions on online expression. And the gulf between the two appears to be widening. In 2017, the Thailand government threatened Facebook with legal action unless it agreed to remove content critical of Thailand’s royal family and, in 2020, Facebook announced it had been ‘forced to block’ such material. Also in 2020, the Vietnam government pressured state-owned telecom companies to throttle internet traffic to Facebook, effectively restricting access to the platform, until Facebook agreed to take down content the government deemed to be anti-state.

Enter email address Subscribe Platforms refuse to silence legitimate criticism However, Silicon Valley’s social media companies have also been pushing back. Facebook restricted the accounts of Myanmar’s military on the basis of ‘spreading misinformation’ in the wake of the military’s imposition of an internet shutdown that blocked access to Facebook, Twitter, and Instagram. And Twitter resisted requests by the Indian government to block accounts involved in protests by farmers. Twitter stated that while it would block any accounts which it felt incited violence, it would not take action on accounts belonging to news media entities, journalists, activists, and politicians because it believed that would ‘violate the fundamental right to free expression under the Indian law’. The Indian government responded by fast-tracking stringent new social media regulations heavily criticized by rights groups for increasing government power over content on social media platforms, including online news. So how can social media companies find avenues for operating in Asia and beyond without being co-opted into the lurch towards digital authoritarianism? There are no easy answers here, but collaboration is key. Cooperation between tech companies and local civil society partners can help companies better understand risks to human rights in the country concerned and how they might be mitigated. And tech companies are more effective in alliance with each other than acting on their own, such as the refusal by Facebook, Google, Telegram, and Twitter to hand over data on protestors to the Hong Kong police. Twitter stated that while it would block any accounts which it felt incited violence, it would not take action on accounts belonging to news media entities, journalists, activists, and politicians The fact that in many countries in Asia there are no alternatives to Western social media companies – unlike China, where platforms such as WeChat are part of the government’s internet control apparatus – gives the companies concerned some leverage. In February 2020, Facebook, Google, and Twitter together – through the Asia Internet Coalition – threatened to leave Pakistan in response to the government’s draconian proposals to regulate social media. Along with pressure and lawsuits from civil society, this forced the government into retreat, although the tussle over the new rules, introduced in November, continues. At a time when illiberalism was already on the rise in Asia (including in democracies – Freedom House has just downgraded India’s status from ‘free’ to ‘partly free’), COVID-19 has made tighter state control of online freedom of expression even more attractive to many governments. As it seems increasingly unlikely that restrictions enacted under the guise of pandemic-related emergency measures will be repealed once the COVID-19 crisis ends, it is even more important that tech companies work with civil society on the ground to minimize the censorship of citizen voices.

The scale of today’s global challenges demand collaborative and coordinated action. But deepening geopolitical competition is threatening multilateralism while growing inequality and social tensions continue to undermine public confidence in the ability of international institutions to deliver. Into this challenging environment, add the complexity and sheer pace of many global challenges such as the climate crisis and the proliferation of new technologies – issues that cannot be addressed effectively by governments alone. How do global institutions and mechanisms need to adapt to address the demands for a fairer distribution of power between states and to engage the diverse set of actors essential today for effective solutions? What can be learnt from existing initiatives that bring together governments, civil society, private sector, cities, next generation leaders and other stakeholders?

And how will Merkel be remembered? In the wake of the storming of Capitol Hill on 6 January 2021, social media platforms took steps to remove former President Donald Trump from their websites for infringing community standards. This step was welcomed by many, but also raised serious questions about the power of social media companies to limit free speech and censor elected officials. The suspension of President Trump from Facebook was referred to the Oversight Board, an independent body of experts set up to scrutinise the platform’s content moderation decisions. In this episode, Ben speaks to Thomas Hughes and Kate Jones about the outcome of the Oversight Board’s inquiry into the Trump suspension, and the wider implications for content moderation on social media. Then Lara is joined by Hans Kundnani to assess the political outlook in Germany and reflect on the legacy of outgoing Chancellor Angela Merkel. Full Article

si Ukraine: Debunking Russia’s legal justifications By www.chathamhouse.org Published On :: Thu, 24 Feb 2022 19:53:50 +0000 Ukraine: Debunking Russia’s legal justifications Expert comment NCapeling 24 February 2022 Russia is violating international law in Ukraine using baseless allegations, and states’ responses should be guided accordingly. Russia has begun a large-scale military attack on Ukraine, having first declared it recognizes Donetsk and Luhansk as separate states. It scarcely needs saying Russia is violating international law – violating the prohibition in the United Nations (UN) Charter on the use of force, violating the obligation to respect the sovereignty and territorial integrity of other states, and violating the prohibition on intervention. But Russia is using the language of the law to defend its actions. In all the recent verbiage of President Vladimir Putin, some attempts at legal arguments can be elicited – but they do not stand up to scrutiny. There have been no threats of force against Russia from Ukraine nor from NATO member states. There is nothing to support a legal justification for Russia’s military attack against Ukraine Article 2(4) of the UN Charter prohibits the threat or use of force with the only two Charter exceptions to this prohibition being self-defence and action mandated by the UN Security Council. In his speech on 23 February, Putin points to two grounds on which Russia relies on self-defence – defence in aid of the two breakaway republics and self-defence in the light of threats against Russia itself. Donetsk, Luhansk, and collective self-defence Putin said ‘the people’s republics of Donbass turned to Russia with a request for help’ and went on to seek to justify his military action under Article 51 of the Charter. But it is only in respect of states that the right of collective self-defence exists – humanitarian intervention on behalf of individuals in a state has not gained a place in international law. And it is only Russia which has recognized the statehood of the two regions. Putin repeated on 23 February his earlier allegation that the people of the two breakaway republics are being repressed by the Ukraine government, and even that genocide is being committed against them. This baseless allegation is relevant not only to the claim of self-defence on behalf of these regions but also to Russia’s ‘recognition’ of them as separate states. International law does not give the inhabitants of a part of a state the right to secede from that state. The aspect of self-determination which allows for independence of a ‘people’ applies to peoples in colonies and other overseas territories under the occupation of another state. The other aspect of self-determination is ‘internal’ and comprises the right to freely choose political status and pursue economic, social, and cultural development within the state – as the Minsk accords sought to provide for Donetsk and Luhansk. There is a somewhat controversial theory in international law that would give a right of secession from a state if the people in question were subject to extreme abuse of human rights and systematic oppression. This is the theory of remedial secession, which some countries, such as Switzerland, used in the International Court of Justice (ICJ) in relation to Kosovo’s declaration of independence from Serbia – an independence still not recognized by Russia. But the theory has no support from the international courts and, even if it did, Russia itself has stated previously that a right of remedial secession is ‘limited to truly extreme circumstances, such as an outright armed attack by the parent State, threatening the very existence of the people in question’ (see Russia’s submissions to the ICJ in the Kosovo case, para 88). Ukraine retained its membership in the UN at the dissolution of the USSR, having been one of the founding members of the UN as the Ukrainian Soviet Socialist Republic The facts do not substantiate Russia’s claims anyway. The law is as stated on behalf of the UN Secretary-General on 21 February – that Russia’s decision to recognize the independence of the breakaway regions is a ‘violation of the territorial integrity and sovereignty of Ukraine and inconsistent with the principles of the Charter of the United Nations.’ There are no ‘states’ which can request the use of military force. Is Ukraine a threat against Russia? Putin refers to the ‘further expansion of the infrastructure of the North Atlantic Alliance, the military development of the territories of Ukraine’ as creating an ‘anti-Russia’ comprising a ‘real threat not just to our interests, but to the very existence of our state, its sovereignty’. Article 51 allows for self-defence ‘if an armed attack occurs’. This has been interpreted by many states to include defence against the threat of an imminent attack – for example, there is no requirement to wait until a nuclear strike has begun. But under no interpretation of ‘imminence’ can the situation in Ukraine constitute a threat to Russia. There have been no threats of force against Russia from Ukraine nor from NATO member states. There is nothing to support a legal justification for Russia’s military attack against Ukraine. The myth of Ukraine never having had ‘real statehood’ also does not give any legal justification for Russian aggression. The UN is based on the ‘principle of the sovereign equality of all its Members’ (Art. 2(1) of the UN Charter). Ukraine retained its membership in the UN at the dissolution of the USSR, having been one of the founding members of the UN as the Ukrainian Soviet Socialist Republic. What are the legal consequences of Russia’s actions? Within the UN, it is the Security Council which has the mandate to uphold international peace and security, and act when there is a threat to the peace. But there will be no help from there with Russia’s status as a permanent member holding a veto. The UN General Assembly may act instead. Since 2014 it has adopted a series of resolutions (the latest on 9 December 2021) requiring Russia to withdraw immediately and unconditionally from Crimea. But the General Assembly does not have the powers of the Security Council, and cannot mandate peacekeepers or the use of force. In due course there may be the need for a UN Human Rights Commission of Inquiry to be launched if there are breaches of human rights law and international humanitarian law, and human rights cases may be brought against Russia at the European Court of Human Rights. But international institutions do not have the necessary powers to stop what is going on right now. International law gives the right to Ukraine, being attacked, to call for support from other states. And as well as imposing sanctions, states may wish to consider cyber countermeasures. Some of the recent cyber activity against Ukraine has been attributed by the US, UK, and Australia to the Russian Main Intelligence Unit (GRU). Full Article
si Geopolitical corporate responsibility can drive change By www.chathamhouse.org Published On :: Tue, 26 Jul 2022 12:55:12 +0000 Geopolitical corporate responsibility can drive change Expert comment NCapeling 26 July 2022 Russia’s long invasion of Ukraine is testing the commitment of business, but this could see the emergence of a new pillar of support for the rules-based international order. The massive exit of more than 1,000 international companies from Russia has surpassed – by a factor of nearly ten in merely four months – the number which pulled out of apartheid-led South Africa over an entire decade. These company exits extend beyond those industries targeted for sanctions – oil and gas, banks and financial services, aerospace, and certain technology sectors – to include hundreds in consumer products ranging from Levi’s and H&M clothing to Coca-Cola and McDonalds. Many of these companies may wish to return to a post-conflict – or post-Putin – Russia, while a few have already sold their Russian operations, as McDonald’s has to an existing Siberian licensee. Both reputational and operational factors are driving the huge exodus: reputational as companies have chosen to disassociate themselves from Putin’s regime; operational as transportation routes and supply chains have been interrupted. Few of these companies have made explicit the principles at stake, while many still face ‘tricky legal, operational and ethical considerations’ and some have kept operations in place. But the collective impact of the exit in response to Russia’s affront to international law has sent shockwaves around the world. Current issues and future implications Minds now turn to whether this exodus sets a blueprint for the future, and how companies having to make complex and sensitive risk assessments and global business planning decisions can address both current issues as well as similar future challenges. The new Declaration from the Business for Ukraine Coalition – an international civil society initiative of organizations and individuals – encourages companies to reinforce ‘responsible exit’ from Russia ‘in response to its unprovoked, full-scale war on Ukraine’. The declaration’s objective is to ‘block access to the economic and financial resources enabling Russian aggression’ and it urgently calls on companies that have terminated or suspended their business operations and relationships to ‘stand by those commitments until the territorial sovereignty of Ukraine within internationally recognized borders is restored.’ Business has a fundamental stake in the international order as the framework for stability, prosperity, open societies, and markets It also states companies yet to terminate or suspend operations in Russia should do so unless they can demonstrate through due diligence that their provision of ‘essential’ services or products – such as medicines – meet critical humanitarian needs. The 2022 Edelman Trust Barometer Special Report: The Geopolitical Business suggests Ukraine represents an inflection point posing ‘a new test’ for business. According to an online survey of 14,000 respondents in 14 countries, including employees, NGOs, and other stakeholders, there is a ‘rising call’ for business to be more engaged in geopolitics, with CEOs ‘expected to shape policy’ on societal and geopolitical issues. Such expectations have been intensifying with the impetus of the combined stakeholder capitalism and corporate purpose agenda, even as a political backlash in the US against the environmental, social, and governance (ESG) movement linking institutional investors and multinational corporations gains momentum. The emergence of corporate activism is a further development – partly driven by employees and accelerated during the pandemic – on issues of economic inequality, racial injustice, and gender equality, as well as the climate crisis. When considering what broader purpose should drive this corporate geopolitical engagement, the Business for Ukraine Declaration offers an answer, calling Russia’s aggression ‘an attack on the rules-based international order which must be protected to ‘safeguard the international community and the global economy.’ This points to broader interests and values at stake in the Russian war on Ukraine because supporting the rules-based international order can become the basis of a new geopolitical corporate responsibility. Business, especially multinational corporations and institutional investors, fundamentally depend on and have enormously benefitted from this order. Economic development needs a stable rules-based international order Trade and investment, entrepreneurship, and innovation – the sinews of economic development – depend on predictable, rational behaviour by states at home and abroad. Individual companies and entire industries share a stake in upholding this order at a time when its stability and even legitimacy is undergoing a severe challenge. A new geopolitical corporate responsibility does not need to become a doctrine but can instead be an agenda to support the international rules-based order under stress The rules-based international order has evolved since the adoption of the UN Charter in 1945, the Universal Declaration of Human Rights in 1948, and the establishment of the standards, norms and institutions that reflect and reinforce these lodestars. It defines the international community, the rule of law, accountable governance, civic freedoms, and human rights within nations. It also supports national self-determination, sovereignty, and the disavowal of the use of force to alter borders among nations, and it provides accountability for genocide, crimes against humanity, and war crimes. Business has a fundamental stake in the international order as the framework for stability, prosperity, open societies, and markets. A new geopolitical corporate responsibility does not need to become a doctrine but can instead be an agenda to support the international rules-based order under stress. Such an agenda may help multinationals deal with expectations they already face, such as: Avoiding situations where they cause, contribute, or are directly linked to human rights abuses. This objective is enshrined in the UN Guiding Principles on Business and Human Rights and companies can be further informed by the new UN Guide to Heightened Human Rights Due Diligence for Business in Conflict-Affected Contexts. Committing to the ‘shared space’ of the rule of law, accountable governance, civic freedoms, and human rights. These are both the enablers of civil society and the underpinning of sustainable and profitable business and investment environments. The Chatham House synthesis paper The role of the private sector in protecting civic space sets forth the rationale for companies to defend these vital elements. Supporting peace, justice, and strong institutions both within nations and across the international community as set forth by UN Sustainable Development Goal 16. The SDG 16 Business Framework: Inspiring Transformational Governance shows how companies, as well as national governments and international institutions, can contribute to these building blocks of stability and prosperity. Demonstrating corporate responsibility at the national and geopolitical levels to enhance equity, transparency, and accountability. Multinationals are already challenged to accept minimum corporate taxation within and across jurisdictions, curb excessive executive compensation, endorse mandatory disclosure of environmental and human rights due diligence, and strengthen corporate governance of ESG risks and responsibilities, including with respect to human rights. Diminishing inequality by tackling poverty and ensuring sustainability by arresting the climate crisis. Alongside governments and international institutions, the business community already faces increasing pressure to improve its efforts in these areas. Full Article
si Seven ways Russia’s war on Ukraine has changed the world By www.chathamhouse.org Published On :: Fri, 17 Feb 2023 10:06:57 +0000 Seven ways Russia’s war on Ukraine has changed the world Feature jon.wallace 17 February 2023 Chatham House experts examine the shifts in geopolitical alliances, security, energy, and supply chains and whether these changes are likely to be long-lasting. President Vladimir Putin’s decision to launch a full-scale re-invasion of Ukraine one year ago was a global shock which ‘marked an abrupt end to 30 years of globalization and all the international co-operation that made that possible’ with serious implications for countries around the world, outlined Chatham House director Bronwen Maddox in her inaugural lecture. Not only has the war threatened the stability of Europe but it has also impacted food and energy security globally including in the Middle East and Africa, creating shock waves in a world barely recovering from the COVID-19 pandemic.

si The ICC response to Russia’s war gives hope for justice By www.chathamhouse.org Published On :: Sun, 19 Mar 2023 19:33:21 +0000 The ICC response to Russia’s war gives hope for justice Expert comment NCapeling 19 March 2023 The ICC’s arrest warrants against Putin and Lvova-Belova show the commission of international crimes is not without consequences. Warrants of arrest for Russian president Vladimir Putin and Maria Alekseyevna Lvova-Belova, commissioner for children’s rights in the president’s office, have been issued because the Pre-Trial Chamber II of the International Criminal Court (ICC) has reasonable grounds to believe they have committed war crimes. Following an independent investigation and evidence-gathering by the ICC prosecutor Karim Khan in his first new case since taking office, the pair are accused of committing two different war crimes – the unlawful deportation of children from Ukraine to Russia, and the unlawful transfer of children from occupied areas of Ukraine to the Russian Federation. The focus on those two war crimes is likely due to clear evidence that deportation and forcible transfer of thousands of Ukrainian children have occurred, as the Russian government was overt about its policy of taking Ukrainian children to Russia and placing them in camps or putting them up for adoption by Russian families. Furthermore, in line with the Office of the Prosecutor’s policy on children, crimes against children are prioritized given their particularly vulnerable status. Jurisdiction and enforcement The ICC does not have jurisdiction over crimes committed fully in Russia by Russian nationals, as Russia is not a party to the Rome Statute which created the ICC. However, it does have jurisdiction over war crimes, crimes against humanity, and genocide committed in Ukraine irrespective of who committed them, pursuant to two declarations lodged by Ukraine in 2014 accepting the Court’s jurisdiction over its territory from November 2013. Making the warrants public enables the ICC to reclaim itself as a key avenue for ensuring accountability for international crimes, following a wave of criticism and disenchantment about its work Although a prosecution has been initiated, it is ultimately for the judges of the ICC to decide on the accused’s fate. But the chances of Putin getting arrested or tried for these offences are slim. The ICC lacks enforcement or police powers and depends on state cooperation to execute arrest warrants. Also, because it cannot try individuals in their absence, a trial or conviction cannot occur without Putin and Lvova-Belova being in custody. But by issuing and unsealing these arrest warrants, the ICC is relying on the symbolic function of international criminal law – it is publicly naming and shaming Putin and Lvova-Belova for the commission of serious atrocities, and it is sending a message to other leaders and the international community that such actions are not without consequence. The arrest warrants also give victims some form of vindication or recognition for their suffering and hope for justice in the future. And making the warrants public enables the ICC to reclaim itself as a key avenue for ensuring accountability for international crimes, following a wave of criticism and disenchantment about its work in Africa and delays in advancing its investigation on Afghanistan. International courts gearing into action This ICC case is the latest in a series of ongoing cases related to Russia’s war in Ukraine before different international courts and tribunals. Others include at least four cases before the European Court of Human Rights for events that occurred before Russia was excluded from the Council of Europe, such as the MH17 flight case and the annexation of Crimea. They showcase an important feature of the global legal system and its judicial architecture that cannot be underestimated – the ability to quickly swing into action in response to violations of international law Two cases have also been brought by Ukraine against Russia before the International Court of Justice – in 2017 and 2022 – with hearings scheduled for June. An unprecedented number of states parties have sought to intervene in one or more of these cases. Each case must be considered on its own merits and the decisions cannot be prejudged. But they showcase an important feature of the global legal system and its judicial architecture that cannot be underestimated – the ability to quickly swing into action in response to violations of international law. In this case, the response was prompted by Russia’s aggression against Ukraine in breach of the United Nations Charter and fundamental principles of international law. A starting point for a bigger case The ICC prosecutor already has a broader investigation into other international crimes committed in Ukraine since 21 November 2013. So this is likely to be just the starting point of a much bigger case against Putin and other senior Russian officials for international crimes committed in the context of the war in Ukraine and within the ICC’s jurisdiction. These potentially include other war crimes such as the indiscriminate or disproportionate targeting of civilians, crimes against humanity, and genocide. Full Article
si The Arg-293 of Cryptochrome1 is responsible for the allosteric regulation of CLOCK-CRY1 binding in circadian rhythm [Computational Biology] By www.jbc.org Published On :: 2020-12-11T00:06:20-08:00 Mammalian circadian clocks are driven by transcription/translation feedback loops composed of positive transcriptional activators (BMAL1 and CLOCK) and negative repressors (CRYPTOCHROMEs (CRYs) and PERIODs (PERs)). CRYs, in complex with PERs, bind to the BMAL1/CLOCK complex and repress E-box–driven transcription of clock-associated genes. There are two individual CRYs, with CRY1 exhibiting higher affinity to the BMAL1/CLOCK complex than CRY2. It is known that this differential binding is regulated by a dynamic serine-rich loop adjacent to the secondary pocket of both CRYs, but the underlying features controlling loop dynamics are not known. Here we report that allosteric regulation of the serine-rich loop is mediated by Arg-293 of CRY1, identified as a rare CRY1 SNP in the Ensembl and 1000 Genomes databases. The p.Arg293His CRY1 variant caused a shortened circadian period in a Cry1−/−Cry2−/− double knockout mouse embryonic fibroblast cell line. Moreover, the variant displayed reduced repressor activity on BMAL1/CLOCK driven transcription, which is explained by reduced affinity to BMAL1/CLOCK in the absence of PER2 compared with CRY1. Molecular dynamics simulations revealed that the p.Arg293His CRY1 variant altered a communication pathway between Arg-293 and the serine loop by reducing its dynamicity. Collectively, this study provides direct evidence that allosterism in CRY1 is critical for the regulation of circadian rhythm. Full Article
si Genetic evidence for partial redundancy between the arginine methyltransferases CARM1 and PRMT6 [Signal Transduction] By www.jbc.org Published On :: 2020-12-11T00:06:20-08:00 CARM1 is a protein arginine methyltransferase (PRMT) that acts as a coactivator in a number of transcriptional programs. CARM1 orchestrates this coactivator activity in part by depositing the H3R17me2a histone mark in the vicinity of gene promoters that it regulates. However, the gross levels of H3R17me2a in CARM1 KO mice did not significantly decrease, indicating that other PRMT(s) may compensate for this loss. We thus performed a screen of type I PRMTs, which revealed that PRMT6 can also deposit the H3R17me2a mark in vitro. CARM1 knockout mice are perinatally lethal and display a reduced fetal size, whereas PRMT6 null mice are viable, which permits the generation of double knockouts. Embryos that are null for both CARM1 and PRMT6 are noticeably smaller than CARM1 null embryos, providing in vivo evidence of redundancy. Mouse embryonic fibroblasts (MEFs) from the double knockout embryos display an absence of the H3R17me2a mark during mitosis and increased signs of DNA damage. Moreover, using the combination of CARM1 and PRMT6 inhibitors suppresses the cell proliferation of WT MEFs, suggesting a synergistic effect between CARM1 and PRMT6 inhibitions. These studies provide direct evidence that PRMT6 also deposits the H3R17me2a mark and acts redundantly with CARM1. Full Article
si Hepatocyte nuclear factor 1{beta} suppresses canonical Wnt signaling through transcriptional repression of lymphoid enhancer-binding factor 1 [Molecular Bases of Disease] By www.jbc.org Published On :: 2020-12-18T00:06:18-08:00 Hepatocyte nuclear factor-1β (HNF-1β) is a tissue-specific transcription factor that is required for normal kidney development and renal epithelial differentiation. Mutations of HNF-1β produce congenital kidney abnormalities and inherited renal tubulopathies. Here, we show that ablation of HNF-1β in mIMCD3 renal epithelial cells results in activation of β-catenin and increased expression of lymphoid enhancer–binding factor 1 (LEF1), a downstream effector in the canonical Wnt signaling pathway. Increased expression and nuclear localization of LEF1 are also observed in cystic kidneys from Hnf1b mutant mice. Expression of dominant-negative mutant HNF-1β in mIMCD3 cells produces hyperresponsiveness to exogenous Wnt ligands, which is inhibited by siRNA-mediated knockdown of Lef1. WT HNF-1β binds to two evolutionarily conserved sites located 94 and 30 kb from the mouse Lef1 promoter. Ablation of HNF-1β decreases H3K27 trimethylation repressive marks and increases β-catenin occupancy at a site 4 kb upstream to Lef1. Mechanistically, WT HNF-1β recruits the polycomb-repressive complex 2 that catalyzes H3K27 trimethylation. Deletion of the β-catenin–binding domain of LEF1 in HNF-1β–deficient cells abolishes the increase in Lef1 transcription and decreases the expression of downstream Wnt target genes. The canonical Wnt target gene, Axin2, is also a direct transcriptional target of HNF-1β through binding to negative regulatory elements in the gene promoter. These findings demonstrate that HNF-1β regulates canonical Wnt target genes through long-range effects on histone methylation at Wnt enhancers and reveal a new mode of active transcriptional repression by HNF-1β.

si MicroRNA-98 reduces nerve growth factor expression in nicotine-induced airway remodeling [Gene Regulation] By www.jbc.org Published On :: 2020-12-25T00:06:30-08:00 Evolving evidence suggests that nicotine may contribute to impaired asthma control by stimulating expression of nerve growth factor (NGF), a neurotrophin associated with airway remodeling and airway hyperresponsiveness. We explored the hypothesis that nicotine increases NGF by reducing lung fibroblast (LF) microRNA-98 (miR-98) and PPARγ levels, thus promoting airway remodeling. Levels of NGF, miR-98, PPARγ, fibronectin 1 (FN1), endothelin-1 (EDN1, herein referred to as ET-1), and collagen (COL1A1 and COL3A1) were measured in human LFs isolated from smoking donors, in mouse primary LFs exposed to nicotine (50 μg/ml), and in whole lung homogenates from mice chronically exposed to nicotine (100 μg/ml) in the drinking water. In selected studies, these pathways were manipulated in LFs with miR-98 inhibitor (anti-miR-98), miR-98 overexpression (miR-98 mimic), or the PPARγ agonist rosiglitazone. Compared with unexposed controls, nicotine increased NGF, FN1, ET-1, COL1A1, and COL3A1 expression in human and mouse LFs and mouse lung homogenates. In contrast, nicotine reduced miR-98 levels in LFs in vitro and in lung homogenates in vivo. Treatment with anti-miR-98 alone was sufficient to recapitulate increases in NGF, FN1, and ET-1, whereas treatment with a miR-98 mimic significantly suppressed luciferase expression in cells transfected with a luciferase reporter linked to the putative seed sequence in the NGF 3'UTR and also abrogated nicotine-induced increases in NGF, FN1, and ET-1 in LFs. Similarly, rosiglitazone increased miR-98 and reversed nicotine-induced increases in NGF, FN1, and ET-1. Taken together, these findings demonstrate that nicotine-induced increases in NGF and other markers of airway remodeling are negatively regulated by miR-98. Full Article
si Inhibition of the SUV4-20 H1 histone methyltransferase increases frataxin expression in Friedreich's ataxia patient cells [Gene Regulation] By www.jbc.org Published On :: 2020-12-25T00:06:30-08:00 The molecular mechanisms of reduced frataxin (FXN) expression in Friedreich's ataxia (FRDA) are linked to epigenetic modification of the FXN locus caused by the disease-associated GAA expansion. Here, we identify that SUV4-20 histone methyltransferases, specifically SUV4-20 H1, play an important role in the regulation of FXN expression and represent a novel therapeutic target. Using a human FXN–GAA–Luciferase repeat expansion genomic DNA reporter model of FRDA, we screened the Structural Genomics Consortium epigenetic probe collection. We found that pharmacological inhibition of the SUV4-20 methyltransferases by the tool compound A-196 increased the expression of FXN by ∼1.5-fold in the reporter cell line. In several FRDA cell lines and patient-derived primary peripheral blood mononuclear cells, A-196 increased FXN expression by up to 2-fold, an effect not seen in WT cells. SUV4-20 inhibition was accompanied by a reduction in H4K20me2 and H4K20me3 and an increase in H4K20me1, but only modest (1.4–7.8%) perturbation in genome-wide expression was observed. Finally, based on the structural activity relationship and crystal structure of A-196, novel small molecule A-196 analogs were synthesized and shown to give a 20-fold increase in potency for increasing FXN expression. Overall, our results suggest that histone methylation is important in the regulation of FXN expression and highlight SUV4-20 H1 as a potential novel therapeutic target for FRDA. Full Article

si Molecular basis for histone H3 “K4me3-K9me3/2” methylation pattern readout by Spindlin1 [Gene Regulation] By www.jbc.org Published On :: 2020-12-04T00:06:06-08:00 Histone recognition by “reader” modules serves as a fundamental mechanism in epigenetic regulation. Previous studies have shown that Spindlin1 is a reader of histone H3K4me3 as well as “K4me3-R8me2a” and promotes transcription of rDNA or Wnt/TCF4 target genes. Here we show that Spindlin1 also acts as a potent reader of histone H3 “K4me3-K9me3/2” bivalent methylation pattern. Calorimetric titration revealed a binding affinity of 16 nm between Spindlin1 and H3 “K4me3-K9me3” peptide, which is one to three orders of magnitude stronger than most other histone readout events at peptide level. Structural studies revealed concurrent recognition of H3K4me3 and H3K9me3/2 by aromatic pockets 2 and 1 of Spindlin1, respectively. Epigenomic profiling studies showed that Spindlin1 colocalizes with both H3K4me3 and H3K9me3 peaks in a subset of genes enriched in biological processes of transcription and its regulation. Moreover, the distribution of Spindlin1 peaks is primarily associated with H3K4me3 but not H3K9me3, which suggests that Spindlin1 is a downstream effector of H3K4me3 generated in heterochromatic regions. Collectively, our work calls attention to an intriguing function of Spindlin1 as a potent H3 “K4me3-K9me3/2” bivalent mark reader, thereby balancing gene expression and silencing in H3K9me3/2-enriched regions.

si Coupled intra- and interdomain dynamics support domain cross-talk in Pin1 [Signal Transduction] By www.jbc.org Published On :: 2020-12-04T00:06:05-08:00 The functional mechanisms of multidomain proteins often exploit interdomain interactions, or “cross-talk.” An example is human Pin1, an essential mitotic regulator consisting of a Trp–Trp (WW) domain flexibly tethered to a peptidyl-prolyl isomerase (PPIase) domain, resulting in interdomain interactions important for Pin1 function. Substrate binding to the WW domain alters its transient contacts with the PPIase domain via means that are only partially understood. Accordingly, we have investigated Pin1 interdomain interactions using NMR paramagnetic relaxation enhancement (PRE) and molecular dynamics (MD) simulations. The PREs show that apo-Pin1 samples interdomain contacts beyond the range suggested by previous structural studies. They further show that substrate binding to the WW domain simultaneously alters interdomain separation and the internal conformation of the WW domain. A 4.5-μs all-atom MD simulation of apo-Pin1 suggests that the fluctuations of interdomain distances are correlated with fluctuations of WW domain interresidue contacts involved in substrate binding. Thus, the interdomain/WW domain conformations sampled by apo-Pin1 may already include a range of conformations appropriate for binding Pin1's numerous substrates. The proposed coupling between intra-/interdomain conformational fluctuations is a consequence of the dynamic modular architecture of Pin1. Such modular architecture is common among cell-cycle proteins; thus, the WW–PPIase domain cross-talk mechanisms of Pin1 may be relevant for their mechanisms as well. Full Article
si Functional and structural characterization of allosteric activation of phospholipase Cϵ by Rap1A [Molecular Biophysics] By www.jbc.org Published On :: 2020-12-04T00:06:05-08:00 Phospholipase Cε (PLCε) is activated downstream of G protein–coupled receptors and receptor tyrosine kinases through direct interactions with small GTPases, including Rap1A and Ras. Although Ras has been reported to allosterically activate the lipase, it is not known whether Rap1A has the same ability or what its molecular mechanism might be. Rap1A activates PLCε in response to the stimulation of β-adrenergic receptors, translocating the complex to the perinuclear membrane. Because the C-terminal Ras association (RA2) domain of PLCε was proposed to the primary binding site for Rap1A, we first confirmed using purified proteins that the RA2 domain is indeed essential for activation by Rap1A. However, we also showed that the PLCε pleckstrin homology (PH) domain and first two EF hands (EF1/2) are required for Rap1A activation and identified hydrophobic residues on the surface of the RA2 domain that are also necessary. Small-angle X-ray scattering showed that Rap1A binding induces and stabilizes discrete conformational states in PLCε variants that can be activated by the GTPase. These data, together with the recent structure of a catalytically active fragment of PLCε, provide the first evidence that Rap1A, and by extension Ras, allosterically activate the lipase by promoting and stabilizing interactions between the RA2 domain and the PLCε core.
