Tyrosine phosphorylation of the scaffold protein IQGAP1 in the MET pathway alters function [Signal Transduction]

IQGAP1 is a key scaffold protein that regulates numerous cellular processes and signaling pathways. Analogous to many other cellular proteins, IQGAP1 undergoes post-translational modifications, including phosphorylation. Nevertheless, very little is known about the specific sites of phosphorylation or the effects on IQGAP1 function. Here, using several approaches, including MS, site-directed mutagenesis, siRNA-mediated gene silencing, and chemical inhibitors, we identified the specific tyrosine residues that are phosphorylated on IQGAP1 and evaluated the effect on function. Tyr-172, Tyr-654, Tyr-855, and Tyr-1510 were phosphorylated on IQGAP1 when phosphotyrosine phosphatase activity was inhibited in cells. IQGAP1 was phosphorylated exclusively on Tyr-1510 under conditions with enhanced MET or c-Src signaling, including in human lung cancer cell lines. This phosphorylation was significantly reduced by chemical inhibitors of MET or c-Src or by siRNA-mediated knockdown of MET. To investigate the biological sequelae of phosphorylation, we generated a nonphosphorylatable IQGAP1 construct by replacing Tyr-1510 with alanine. The ability of hepatocyte growth factor, the ligand for MET, to promote AKT activation and cell migration was significantly greater when IQGAP1-null cells were reconstituted with IQGAP1 Y1510A than when cells were reconstituted with WT IQGAP1. Collectively, our data suggest that phosphorylation of Tyr-1510 of IQGAP1 alters cell function. Because increased MET signaling is implicated in the development and progression of several types of carcinoma, IQGAP1 may be a potential therapeutic target in selected malignancies.

Arguments Over Innovation Capacity Miss How Much the US and China Are Intertwined

Arguments Over Innovation Capacity Miss How Much the US and China Are Intertwined Expert comment sysadmin 30 May 2018

Most discussions of current US–China trade tensions fundamentally misrepresent the globalized nature of innovation.

Among the many issues at play in the ongoing economic and trade tensions between the US and China are questions of technological capability and innovation.

Two of the main complaints in the US Section 301 report were that American companies have been forced to transfer technology to China and been the subject of cyber espionage. The presentation of the issues in this report has been disputed, but behind it lies concern in the US that Chinese innovative and technological capability is catching up with that in the US, thanks partly to the support of state policies set out in the Made in China 2025 initiative.

One important feature of the package of measures announced by the US last month is that it was designed to contain China’s technological development as much as to reduce the trade deficit, even though the latter has been the focus of President Donald Trump’s rhetoric.

(Some have cast doubt on this picture of Chinese innovation, suggesting that China is more of a ‘fat tech dragon’ whose massive inputs into research and development do not translate into real innovative capacity.)

The problem with the debate comparing Chinese and American technological capability is that it misunderstands or misrepresents the globalized nature of innovation in today’s world.

Contrary to the economic nationalist rhetoric emanating mainly from Washington, and to a lesser extent from Beijing, the US and China are not two separate economies competing for economic hegemony. As part of the globalization of manufacturing and production over the last 40 years and the more recent globalization of consumption, the shape and structure of innovation has also changed.

As we argue in a new paper, the key to understanding this is to think of innovation as being carried out through global or transnational networks linking economic actors, not within separated economies. What the recent phase of globalization has demonstrated is that innovation is achieved most effectively and efficiently when those engaged in innovation are connected not just within national borders but across them.

China has become integrated into these global innovation networks in ways which reflect its relative strengths and weaknesses in research and development. China’s extensive manufacturing ecosystem has enabled its companies to perform well in production-related and efficiency-driven innovation. Moreover the rapid growth in its large and dynamic consumer market provides fertile ground for consumer-related innovation by Chinese and foreign-invested enterprises alike. The rapidly increasing talent pool in China also provides additional human capital for innovation and technology.

Apart from the increased emphasis by Chinese enterprises on innovation, multinationals have also been stepping up their research and development (R&D) efforts in China. These now consitute a significant part of China’s R&D landscape, and are an increasingly important part of the global innovation by multinationals.

Things are of course changing. China’s overall innovation capacity is improving, and there are concerns in both in the US and Europe that Chinese policy is moving backwards towards the promotion of ‘indigenous innovation’ – or self-reliant innovation – and away from openness. In other words, we may be seeing a more ‘techno-nationalist’ China as well as a protectionist US.

China has also been criticized for inadequate protection of intellectual property rights, though the establishment of special courts for such disputes marks a commitment to improve – and the rights of Chinese companies increasingly need protection too.

As the benefits of globalization increasingly come under question, and with some degree of nationalist political pressure in both the West and China, it is not going to be possible – or politically desirable – to do away with national borders when it comes to innovation. But at the same time, the extent to which businesses and consumers have globalized means that fully ‘indigenous’ innovation is not possible, even if it were politically desirable.

EU-China innovation relations, as well as those between Washington and Beijing, therefore need careful management. But both Americans and Europeans should have more confidence in their innovation capability, given the relative strengths and weaknesses of Chinese innovation.

Americans and Europeans should acknowledge and promote the opportunities that come from globally networked innovation processes. Taking advantage of the comparative advantage of all the players in these networks means working with China as an innovation partner.

Divided US support shows time is not on Ukraine’s side

Divided US support shows time is not on Ukraine’s side Expert comment LJefferson 17 February 2023

Growing public opinion evidence and uncertainty about the future of the war suggests that continued American support for aiding Ukraine should not be assumed.

One year into Russia’s war on Ukraine, fears that American support for Kyiv would rapidly wane have proven demonstrably wrong. Western financial and military backing has been robust thanks to allied unity and an unexpectedly mild winter. But, as financial analysts constantly remind us, past performance is no guarantee of future results.

People like to back winners. If the anticipated Russian spring offensive looks successful or the counterpart Ukrainian offensive is uninspiring, expect louder US voices calling for a negotiated settlement. The warning signs are already here.

American officials privately express growing apprehension that there will be an early resolution of the conflict. As one White House official recently observed to me, by the end of the year the war could well be about where it is today. And a plurality of Americans intuitively grasp this: 46 per cent believe neither Russia nor Ukraine currently has the advantage in the conflict.

Momentum matters  

In public opinion, perception of momentum matters. Americans’ support for the Vietnam War waned as the conflict persisted, falling from six-in-ten Americans in 1965 to four-in-ten in 1973.

Similarly, backing for the Iraq war fell from more than seven-in-ten in 2003 to barely four-in-ten in 2008. And with Afghanistan, as the war dragged on, support for US involvement fell from more than nine-in-ten in 2002 to less than five-in-ten in 2021. Notably, once the American public turned on these wars, support never returned.

Of course, Americans were fighting and dying in those wars, which is not the case in the Ukraine conflict. But initially the Vietnam, Iraq, and Afghanistan war support was buoyed by the belief that continued US engagement was justified, otherwise American sons and daughters had died in vain. With no American lives at stake in Ukraine, only financial and military resources, there is a growing wariness of throwing good money after bad.

In the last year, the share of Americans who say the United States is doing too much for Ukraine has nearly quadrupled, from seven to 26 per cent. And the portion that believe Washington has not done enough has halved, from 49 per cent to 17 per cent.

Sentiment about Ukraine support has become increasingly partisan. In March 2022, nine per cent of Republicans and five per cent of Democrats said the US was doing too much for Ukraine. By January 2023, 40 per cent of Republicans but just 15 per cent of Democrats complained Washington was doing too much.

In the last year, the share of Americans who say the United States is doing too much for Ukraine has nearly quadrupled, from 7% to 26%.

This erosion of Americans’ support for Ukraine does not bode well for the future. Less than half (48 per cent) of the public in November, compared to 58 per cent in July, believed Washington should support Ukraine for as long as it takes, even if it means American households have to pay higher gas and food prices as a consequence.

A similar share, 47 per cent – up from 38 per cent in July – said the United States should urge Ukraine to settle for peace as soon as possible so the costs aren’t so great for American households, even if that means Ukraine will lose some territory.

A partisan divide

The partisan divide over Ukraine is largely driven by Republican political rhetoric during and after the 2022 midterm elections. Current Republican Speaker of the House Kevin McCarthy observed last October: ‘I think people are going to be sitting in a recession and they’re not going to write a blank cheque to Ukraine.’

More recently, in the wake of Ukrainian president Zelenskyy’s December speech to Congress, Florida Republican Representative Matt Gaetz, whose vote was pivotal in making McCarthy Speaker, tweeted: ‘Hemorrhaging billions in taxpayer dollars for Ukraine while our country is in crisis is the definition of America last.’

In January, newly-elected Ohio Republican Senator J.D. Vance told a Cleveland radio station that it was ‘ultimately not in our national security interest’ to send M1 Abrams tanks to Ukraine, despite the fact that they will be built by his constituents in Ohio.

In addition, ten Republican members of the House of Representatives have introduced legislation asserting ‘that the United States must end its military and financial aid to Ukraine, and urges all combatants to reach a peace agreement.’ 

And this month former President Donald Trump said: ‘That war has to stop, and it has to stop now, and it’s easy to do’ and it ‘can be negotiated within 24 hours’. Why worry about continued support for the war if it’s about to be over?

The road to 2024

With the 2024 US presidential election already revving up, Americans’ appetite for continued backing for Ukraine may hinge on how voters judge the Biden administration’s handling of the conflict.

Democrats are more than twice as likely as Republicans (61 per cent versus 27 per cent) to approve of the Biden administration’s response to the Russia invasion, suggesting Ukraine will be yet another partisan talking point as the campaign heats up. Notably, men are much more likely than women to approve of Biden’s efforts, as are older Americans compared with younger Americans.

World in brief: Ukraine and nuclear proliferation to dominate G7

World in brief: Ukraine and nuclear proliferation to dominate G7 The World Today mhiggins.drupal 28 March 2023

Following Russia’s ongoing intimidation, Japan will use its presidency of the G7 – and its history – to prioritize the dangers of nuclear threats, writes James Orr.

Two issues are expected to dominate the agenda as Japan hosts the G7 summit in Hiroshima from May 19-21. Central to talks will be the conflict in Ukraine, with member states eager to highlight a message of unity and resolve in the face of Russia’s continuing aggression.

Fumio Kishida, Japan’s prime minister, made an unannounced visit to Kyiv on March 21, meeting the Ukrainian president Volodymyr Zelenskyy.  This coincided with a visit to Moscow by China’s leader Xi Jinping, who described Russian president Vladimir Putin as a friend and partner.

‘Absolutely unacceptable’

Hosting the G7 summit in Hiroshima is significant, too, with Kishida expected to emphasize the ‘absolutely unacceptable’ threat of nuclear proliferation. Ongoing tensions between China and Taiwan, together with recent North Korean ballistic missile tests, have heightened fears of a breakdown in security in the region.

A North Korean ballistic missile recently went into the sea near the Japanese island of Hokkaido

Meanwhile, President Vladimir Putin’s menacing references to the use of nuclear weapons in Ukraine has raised the prospect of a potentially devastating conflict with NATO. ‘Kishida’s principal goal for the presidency of the G7 is to try to draw the world away from the path of destruction that is another nuclear conflict,’ said Duncan Bartlett, a research associate at SOAS, the School of Oriental and African Studies, in London.

‘Early last year, Putin warned of terrible consequences if NATO and the West interfered in the Ukraine conflict, and that was widely seen as being a nuclear threat. North Korea is also pursuing its nuclear weapons programme, and in February an intercontinental ballistic missile went into the sea just near the northern Japanese island of Hokkaido,’ said Bartlett.

After Russia invaded Ukraine in February 2022, Kishida has taken a firm position on Putin, in line with his G7 peers. President Zelenskyy has addressed the Japanese parliament via video link and Dmytro Kuleba, Ukraine’s minister of foreign affairs, was invited by his Japanese counterpart to a G7 meeting held during the Munich Security Conference earlier this year.

Kishida committed $600 million in financial support to Ukraine and his government may well announce the provision of further non-lethal assistance to Zelenskyy at the summit. The country’s constitution effectively outlaws the export of deadly weapons to foreign forces. On his visit to Kyiv, Kishida promised a further $30 million to Ukraine.

We are witnessing a shift in the identity and purpose of the G7

Tristen Naylor, University of Cambridge

‘Kishida has revised key defence documents and is pursuing a radical and controversial expansion of Japan’s defence budget and capabilities,’ said Hugo Dobson, Professor of Japan’s International Relations at the University of Sheffield.

‘He and his G7 partners have signed historic defence agreements, pledged to strengthen ties or declared the inseparability of their security in light of actual conflict in Ukraine and potential conflict in East Asia. Kishida has linked the two by emphasizing that Ukraine today may be East Asia tomorrow,’ said Dobson.

Aside from security matters, Kishida will at the summit address issues on clean energy, climate change, global health and boosting multilateral cooperation to drive post-pandemic economic recovery.

Invitation to Nagasaki

He is understood to have invited President Joe Biden to visit Nagasaki, where the second of America’s two atomic bombs is estimated to have killed 60,000 people in August 1945. No sitting US president has ever visited the city, and Kishida, who grew up in Hiroshima, may see the visit as an opportunity to boost his flagging domestic approval ratings. It may also serve as a timely reminder to Russia and others that the G7 opposes any future nuclear weapon use.

Enhanced enzyme kinetics of reverse transcriptase variants cloned from animals infected with SIVmac239 lacking viral protein X [Microbiology]

HIV Type 1 (HIV-1) and simian immunodeficiency virus (SIV) display differential replication kinetics in macrophages. This is because high expression levels of the active host deoxynucleotide triphosphohydrolase sterile α motif domain and histidine-aspartate domain–containing protein 1 (SAMHD1) deplete intracellular dNTPs, which restrict HIV-1 reverse transcription, and result in a restrictive infection in this myeloid cell type. Some SIVs overcome SAMHD1 restriction using viral protein X (Vpx), a viral accessory protein that induces proteasomal degradation of SAMHD1, increasing cellular dNTP concentrations and enabling efficient proviral DNA synthesis. We previously reported that SAMHD1-noncounteracting lentiviruses may have evolved to harbor RT proteins that efficiently polymerize DNA, even at low dNTP concentrations, to circumvent SAMHD1 restriction. Here we investigated whether RTs from SIVmac239 virus lacking a Vpx protein evolve during in vivo infection to more efficiently synthesize DNA at the low dNTP concentrations found in macrophages. Sequence analysis of RTs cloned from Vpx (+) and Vpx (−) SIVmac239–infected animals revealed that Vpx (−) RTs contained more extensive mutations than Vpx (+) RTs. Although the amino acid substitutions were dispersed indiscriminately across the protein, steady-state and pre-steady-state analysis demonstrated that selected SIVmac239 Vpx (−) RTs are characterized by higher catalytic efficiency and incorporation efficiency values than RTs cloned from SIVmac239 Vpx (+) infections. Overall, this study supports the possibility that the loss of Vpx may generate in vivo SIVmac239 RT variants that can counteract the limited availability of dNTP substrate in macrophages.

New essay anthology examines the future of the international order

New essay anthology examines the future of the international order News release jon.wallace 7 May 2021

Featuring a new essay by Robin Niblett, Chief Executive of Chatham House, and Leslie Vinjamuri, Director of the US and Americas programme.

Anchoring the World”, a new anthology, features an important new essay by Robin Niblett, Chief Executive of Chatham House, and Leslie Vinjamuri, Director of the US and Americas programme. The essay, “The Liberal Order Begins At Home”, argues powerfully for the revival of a liberal international order.

The essay collection has been produced by the Lloyd George Study Group on World Order, and celebrates the centennial years of Chatham House, Georgetown University’s School of Foreign Service, and the Council on Foreign Relations.

Robin Niblett said:

“In this excellent collection, some authors argue that the United Nations should continue to anchor the international system, while others argue for the creation of a new Concert of Powers.

“Our essay argues that it is both necessary and possible to revive the idea of a liberal international order: necessary (and urgent) because of heightened global competition with China, and possible only if western democracies repair their deep social and economic problems at home.

“We hope this volume carries forward the fortitude and creative spirit that the School of Foreign Service, Chatham House, and the Council on Foreign Relations have brought to the study and practice of international affairs over the past century.”

The Lloyd George Study Group and book were made possible by the generosity of the family of Robert Lloyd George, the great-grandson of British Prime Minister, David Lloyd George.

Anchoring the World is published by Foreign Affairs magazine.

Redefine the Commonwealth now to safeguard its future

Redefine the Commonwealth now to safeguard its future Expert comment NCapeling 6 October 2022

Although seen as one of the Queen’s greatest legacies, the Commonwealth must provide tangible benefits to its citizens in an era of geopolitical competition.

The Commonwealth’s breadth allows a wide diversity of countries of different sizes, geographies, cultures, and values to be members – it is both rich and poor, north and south, and ethnically diverse. This makes it more interesting than many other multilateral institutions such as the G7, NATO, and the European Union (EU).

But it suffers from an unclear purpose. Since its inception, successive UK governments have grappled with its role – whether it is a preferential trading bloc or merely a source of most of Britain’s post-war immigration.

This lack of purpose – and structure – has left the Commonwealth impotent in dealing with a host of bilateral difficulties between the UK, its overseas territories, and Commonwealth partners in recent years.

Brexit could induce Britain to re-prioritize the Commonwealth, but so far the UK has only signed two new trade deals with Commonwealth members – Australia and New Zealand – while development aid, one of the most tangible ways the UK worked with many Commonwealth countries, has been cut and the UK’s defence focus has pivoted towards the Indo-Pacific and Europe’s Eastern front.

The UK and its allies may find that diplomatic efforts – such as condemning China or Russia for human rights abuses – are more successful if they have listened to and acted on fellow Commonwealth countries’ concerns

The UK also suffered embarrassing and overwhelming defeats in both the UN General Assembly (UNGA) and the International Court of Justice (ICJ) on the legality of its continued occupation of the Chagos Islands and has avoided directly challenging India’s tacit support for Russia’s invasion of Ukraine in the hope of securing a trade deal.

At the recent Commonwealth Heads of Government Meeting (CHOGM), Boris Johnson reportedly attempted to depose Baroness Scotland, the Commonwealth’s Secretary General, but suffered a humiliating defeat in a vote of Commonwealth members.

These challenges are likely to continue, especially in the wake of the death of HM The Queen which could be seen by republican movements as an opportune time to rally support. Australia and New Zealand’s leaders, both republicans, downplayed the idea of a poll on the monarchy immediately after the Queen’s death, but it would be a mistake to assume this has gone quiet forever. Antigua and Barbuda’s prime minister has already said there will be a referendum on becoming a republic within three years.

Defining a new vision for the future

A concrete vision for the Commonwealth is long overdue and there is no better time to cast one than now. HM The Queen was more than just a figurehead for the Commonwealth and it remains unknown exactly what role King Charles III will see for himself.

But, unlike his mother who was a young, modern Queen heralding a post-imperial future, Charles takes the throne at a later age and at a time when important questions need to be addressed in an increasingly fractured world.

Most importantly the UK should avoid the temptation to define the Commonwealth in terms of shared principles and values. India, Pakistan, and Bangladesh all abstained on the United Nations (UN) motion condemning Russia’s invasion of Ukraine, and Commonwealth members are likely to be similarly divided over China’s territorial claims, the US-China conflict, the net-zero agenda, and nuclear non-proliferation.

The Commonwealth’s breadth – its greatest strength – means consensus is often impossible, and so should not be the goal. Instead the Commonwealth should focus on tangible areas of cooperation where there is mutual interest such as trade, aid, and migration.

Brexit could induce Britain to re-prioritize the Commonwealth, but so far the UK has only signed two new trade deals with Commonwealth members – Australia and New Zealand

The UK and its allies may find that diplomatic efforts – such as condemning China or Russia for human rights abuses – are more successful if they have listened to and acted on fellow Commonwealth countries’ concerns, from post-COVID vaccine provision to climate financing. Boosting the aid budget and opening borders may prove more important in engaging developing country partners than traditional diplomatic avenues.

Liz Truss’s British International Investment project could be a valuable vehicle for financing, especially if it leverages private sector funding, but many Commonwealth countries are feeling the more immediate impact of the UK’s aid cuts. In these circumstances many have already turned to Chinese infrastructure financing.

This is where the Commonwealth could be valuable. In the Pacific, it links certain island nations to the UK, Australia, and New Zealand at a time of renewed geopolitical competition with China in the Pacific. The fact the Commonwealth is not explicitly about promoting a particular ideology or countering China is helpful.

Commonwealth should be less UK-centric

There is also no reason why all the Commonwealth operations need to be based in London, which is not only expensive but also reinforces an approach to governance that assumes everything must be decided by civil servants in London. As the world’s largest democracy, India is an obvious alternative candidate although its reluctance to condemn Russia’s invasion and its domestic political tensions may count against it.

It is also important the Commonwealth’s wealthier members – the UK, Canada, and Australia – provide financing for countries such as India to take on extra responsibilities. The Commonwealth Games is a good place to start – despite having 72 competing nations and territories, the games have only been held three times outside the UK, Canada, Australia, and New Zealand.

The Commonwealth also needs to be forward-looking and one of its most exciting assets is its demographic youthfulness. Europe, China, and the US have ageing populations whereas Nigeria, India, and Bangladesh have some of the world’s largest young populations.

Differential compartmental processing and phosphorylation of pathogenic human tau and native mouse tau in the line 66 model of frontotemporal dementia [Molecular Bases of Disease]

Synapse loss is associated with motor and cognitive decline in multiple neurodegenerative disorders, and the cellular redistribution of tau is related to synaptic impairment in tauopathies, such as Alzheimer's disease and frontotemporal dementia. Here, we examined the cellular distribution of tau protein species in human tau overexpressing line 66 mice, a transgenic mouse model akin to genetic variants of frontotemporal dementia. Line 66 mice express intracellular tau aggregates in multiple brain regions and exhibit sensorimotor and motor learning deficiencies. Using a series of anti-tau antibodies, we observed, histologically, that nonphosphorylated transgenic human tau is enriched in synapses, whereas phosphorylated tau accumulates predominantly in cell bodies and axons. Subcellular fractionation confirmed that human tau is highly enriched in insoluble cytosolic and synaptosomal fractions, whereas endogenous mouse tau is virtually absent from synapses. Cytosolic tau was resistant to solubilization with urea and Triton X-100, indicating the formation of larger tau aggregates. By contrast, synaptic tau was partially soluble after Triton X-100 treatment and most likely represents aggregates of smaller size. MS corroborated that synaptosomal tau is nonphosphorylated. Tau enriched in the synapse of line 66 mice, therefore, appears to be in an oligomeric and nonphosphorylated state, and one that could have a direct impact on cognitive function.

Addressing Russia’s use of forced displacement in Ukraine

Addressing Russia’s use of forced displacement in Ukraine 7 November 2024 — 12:30PM TO 2:00PM Anonymous (not verified) Chatham House and Online

Experts consider the role international law could play in responding to Russia’s forcible movement of people during its war against Ukraine.

In the two and a half years since its full-scale invasion of Ukraine, evidence has emerged of Russia’s use of forced deportation and forcible transfer. Russia has also employed arbitrary detention as a tool of war and occupation.

Much attention has been on the International Criminal Court’s arrest warrants against Russian President Vladimir Putin and his children’s commissioner Maria Alekseyevna Lvova-Belova. These warrants were issued in relation to the alleged war crimes concerning the unlawful deportation of children from Ukraine to Russia and the unlawful transfer of thousands of children from occupied areas of Ukraine.

Meanwhile, Ukrainian citizens are being arrested and sent to Russia to serve prison sentences. They are often detained without charge and conviction.

This panel discussion explores:

  • What evidence is emerging of Russia using unlawful deportation and transfer of children, and the arbitrary detention of civilians?
  • What is the role and significance of international law on these issues?
  • What challenges might these practices create for later peace negotiations, as well as the securing of justice?
  • What is the process of releasing illegally detained Ukrainians, and Ukrainian children in particular, and reuniting them with their families? How do Russian volunteers inside Russia cooperate with Ukrainian NGOs to facilitate family reunification?

The event includes a screening of part of the documentary After the Rain: Putin’s Stolen Children

The institute occupies a position of respect and trust, and is committed to fostering inclusive dialogue at all events. Event attendees are expected to uphold this by adhering to our code of conduct.

Egypt’s purchase of a Chinese fighter jet is a reminder Cold War tactics are back in the Middle East

Egypt’s purchase of a Chinese fighter jet is a reminder Cold War tactics are back in the Middle East Expert comment LJefferson

The Egyptian army is a formidable force lacking air superiority capabilities to match its size and ambitions. China understood this predicament and offered to help.

The reported agreement for Egypt to buy the Chinese Chengdu J-10C 4.5 generation fighter jets is part of a broader shift from focusing on modernizing ground troops to bolstering the air force. The details of the deal have not yet been published. Nonetheless, it reveals Egypt has two motivations beyond backing its arsenal with another fighter jet.

Elusive Western technology

The most important motivation for Egypt’s military diversification strategy (and the biggest source of frustration) is the perceived Western technology starvation.
   
A quick examination of the map around Egypt shows that the most significant perceived threats to its national security are located in remote places where Egypt doesn’t traditionally enjoy ground troops’ presence. These include Ethiopia, the Southern Red Sea, Libya and the vulnerability a potential Israel–Iran regional war would create. From the generals’ perspective in Cairo, this list is more than a catalyst to build a modern and capable long arm.

The race started in 2015 after the Obama administration paused an arms transfer to Cairo in 2013 that included four F-16C Block 52 fighter jets amid toppling the Muslim Brotherhood government. The psychological effect of Washington’s decision in Cairo increased Egypt’s risk tolerance towards challenging its military ties with the US by diversifying away from it. 

Egypt ordered the MiG-29M2 fighter jets from Russia and the French Rafales this same year. In 2018, Egypt negotiated a $2 billion deal with Russia to purchase the Su-35 fighter jet, seen in Washington as crossing a red line and triggering a warning to Egypt that it would impose sanctions under the Countering America’s Adversaries Through Sanctions Act (CAATSA). This caused the deal to collapse.

The main factor of the US military sales in the Middle East is the upholding of the Israel Military Qualitative Edge principle over its neighbours. This principle requires the US to ensure Israel is superior over other regional countries’ strategic military capabilities, especially in air power.

For Egypt, this has long been a strategic vulnerability. The US turned down multiple requests by Egypt to purchase the active radar long-range AIM-120 AMRAAM fire-and-forget missile that can be launched from the F-16 fighter jets, the main striking force in Egypt’s arsenal. 

Unlike the Gulf and other states (such as Jordan and Turkey), Egypt was only allowed the old AIM-7 Sparrow and the AIM-9 Sidewinders, which are shorter in range and technologically inferior. Israel also allegedly pressured the Trump administration to refuse Egypt’s request to buy the F-35 stealth fight jets in 2019.

The US and Israel reportedly pressured France to not sell to Egypt the MBDA’s Meteor 100 km air-to-air missile with the Rafale fighters. Instead, Egypt received the 80 km MICA missile as part of the deal to buy 30 Rafales in 2021. Acquiring this advanced radar system and long-range missiles was likely behind Cairo’s deal to purchase 24 Eurofighter Typhoon aircraft from Italy in 2022. However, it is unlikely that they will come with the full package.

Egypt thought the Chinese J-10C Vigorous Dragon fighter may solve this predicament. The Chinese fighter has a beyond-visual range AESA radar and can carry the PL-15 200 km air-to-air missile, similar to the Rafale’s Meteor. The J-10C’s price tag is attractive for Egypt at $40-50 million, much less than the F-16 and Rafales.

The Chinese fighters are also a hedge against Russia’s sanctioned fighter jets, traditionally a second choice for the Egyptian air force.

Risky manoeuvres 

This doesn’t mean Egypt is on a path to abandon its weapons purchases from its Western partners. Egyptian weapons procurement policy is not only motivated by technical considerations. It also serves political objectives. Egypt still receives $1.3 billion every year in military and economic aid from Washington. Regime security and backing are two objectives that will likely encourage Cairo to rely on Western weapons systems for decades. 

However, from Egypt’s military perspective, the time may have come to resort to the Cold War tactics of diversification and counterbalancing. Being forced to accept old technology during the significant modernization of its air force creates a technical and operational necessity to seek this technology elsewhere. 

Egyptian weapons procurement policy is not only motivated by technical considerations. It also serves political objectives.

The regional uncertainty since Hamas’s 7 October attack on Israel and the war that followed in Gaza, southern Lebanon, and Israel’s intermittent confrontations with Iran makes make it imperative for the Egyptian strategic planners to take risky manoeuvres while targeting specific capabilities they seem desperate to acquire. 

The threat to deploy CAATSA sanctions against Egypt in 2019 makes the J-10C deal with China an interesting case study for all Middle Eastern allies of the West. It shows an uptick in Egypt’s risk tolerance to overcome its technological dilemma. It allows other countries considering the Chinese fighters (mainly Saudi Arabia) to gauge Washington’s reaction and design their future approach accordingly.   

Another motivation is to pressure the US, UK, and their allies to reconsider their implicit embargo on certain advanced technology by showing that Cairo now has alternatives. This tactic seems to work. General Frank McKenzie, the former head of US Central Command, said during a congressional hearing in 2022 that Washington will finally provide Egypt with the F-15 heavy-weight air superiority fighter, a longstanding demand by Cairo.

Building favours

The J-10C fighter jet ticks all the boxes: It satisfies Cairo’s diversity strategy and technological needs. It is under the sanctions threshold since it is less technologically savvy than the most controversial J-20 5th generation fighters, the equivalent to Russia’s SU-35. And it takes Egypt’s military partnership with China to a new level.

A heavyweight military power like Egypt relying on Chinese fighters would almost certainly boost China’s share in the regional weapons market.

The rumour that the Chinese fighters are bought to replace the ageing versions of Egypt’s significant F-16 fleet is a source of pride for Beijing since its military technology started to be seen as a competitor to Western technology. A heavyweight military power like Egypt relying on Chinese fighters would almost certainly boost China’s share in the regional weapons market, just like Cairo’s purchase of the Rafale boosted its popularity globally.

US election rhetoric on migration undermines Washington’s soft power in Latin America

US election rhetoric on migration undermines Washington’s soft power in Latin America Expert comment jon.wallace

As US public opinion hardens, the Democratic party takes a tougher stance, and Donald Trump proposes mass deportations, Latin American leaders note a lack of long-term policy.

The US’s broken immigration system has become a central theme of the 2024 election campaign. But the discussion on immigration, undocumented immigrants, and asylum seekers – increasingly lurching into dehumanizing rhetoric – extends beyond US borders. 

As one former senior director of the National Security Council told me, ‘when the president travels or meets with heads of state from Latin America what comes up –regardless of the country – isn’t US–Cuba policy or even trade. It’s immigration’. How the US talks about and treats citizens of Latin American and the Caribbean matters to elected politicians in the region. 

The roots of the US immigration debate go deep and will not be easily resolved, even with a sweeping reform of the system. 

According to a January 2024 Pew survey, 78 per cent of Americans ‘say the large number of migrants seeking to enter the country at the Mexico border is either a crisis (45 per cent) or a major problem (32 per cent)’. Worries about the border are not limited to Republican voters: 73 per cent of Democrats feel that the issue is either a crisis or major problem. 

The numbers of undocumented immigrants encountered at the US–Mexico border has actually dropped in recent months.

Despite the heated popular temperature, the numbers of undocumented immigrants encountered at the US–Mexico border has actually dropped in recent months. US Customs and Border Protection (USCBP) reported 301,981 encounters with irregular border crossings in December 2023; by August 2024 this had dropped to 107,473.  

Nevertheless, illegal border crossings have increased under Biden. During his administration USCBP reported 8 million encounters along the Mexico border compared to 2.5 million under Donald Trump. 

Mexico

Any attempt to address the issue promises to affect US relations with Mexico, requiring the cooperation of newly elected president Claudia Sheinbaum. Her predecessor and founder of her Morena party, leftist Andres Manuel Lopez Obrador (AMLO), proved an unexpectedly cooperative partner for the previous Trump administration and Biden White House. 

In return for AMLO’s cooperation, the US soft-pedalled criticism over his failures to disrupt narcotics trafficking and criminal networks.

But that came at a cost, particularly for Biden. In return for AMLO’s cooperation, the US soft-pedalled criticism over his failures to disrupt narcotics trafficking and criminal networks and for his steady weakening of checks on executive power. 

Mexico’s borders with other countries are also under pressure. Mexico remains the primary sending country to the US. But political repression and insecurity in countries including Cuba, Ecuador, Guatemala and Venezuela has pushed their citizens to travel across Mexico to the US. Economic collapse and humanitarian crises in Cuba and Venezuela have further fuelled the flight.

Rhetoric

The Kamala Harris and Trump campaigns have struck different positions on how to stem the flow of illegal immigration. But as US public opinion shifts, both parties are talking tougher. 

Harris is continuing Biden’s hardening stance, including the controversial move to bar those who cross the border illegally from applying for asylum

Biden’s early ‘roots’ strategy, to provide economic and security support in countries from where migrants are travelling, has fallen by the wayside. 

The Trump campaign is taking more extreme positions. The Republican presidential candidate mentions immigration in almost every campaign speech

He proposes to carry out the ‘largest deportation in US history’, using ICE personnel, the National Guard and local police forces to round up undocumented immigrants, including in their workplaces. 

The campaign has also pledged to end birth-right citizenship and Biden’s programme of parole for humanitarian reasons. Trump also plans to restore his first term policies including construction of the border wall. 

Trump’s proposals provide little opportunity for a broad, bipartisan consensus on immigration. Should he win in November he is likely, as he did in his first term, to attempt to push his policies via executive action, opening up challenges in federal court. 

A Harris victory would at least create space for the resurrection of the Biden administration’s 2024 immigration enforcement bill, originally supported by moderate Republican leadership in the Senate, but defeated following pressure from Trump

The bill would have toughened enforcement at the border – increasing funding for detention centres, asylum hearings and for local governments and border patrols. It would also permit ICE to shut down the border when crossings surpassed an average of 5,000 per day or 8,500 on a single day.

Undermining US influence

But such legislation, while promising to address domestic US perceptions of the crisis, threatens to reduce US soft power in Latin America. That would be counterproductive at a time when the US is attempting to consolidate global support in its competition with China and conflict with Russia. 

For Latin American leaders, US rhetoric on immigration rankles. The priorities of Latin American and Caribbean leaders and their voters are long term: economic growth, improved security, and climate change. These issues require investment and commitment from an engaged and reliable US partner. Sadly, Latin Americans can see such issues are not on the domestic agenda in US politics. 

To improve regional perceptions of US intentions after the election, new policy should seek to address the root causes of migration. That will require a multi-pronged, bipartisan approach that focuses attention and resources on US neighbours south of the border.  

Any future US administration will need to risk unpopularity with some voters at home and engage with sending countries and their neighbours. 

The US’s immigration system will need to broaden paths for legal immigration to meet US labour needs, while delivering increased support for border security, and accelerated (and humane) processes for detaining and repatriating illegal border crossers and asylum claims.  

But any sustainable answer also requires addressing the multifaceted reasons driving migrants north. Any future US administration will need to risk unpopularity with some voters at home and engage with sending countries and their neighbours.

Can Trump do a deal with Putin on Ukraine?

Can Trump do a deal with Putin on Ukraine? Expert comment jon.wallace

The Kremlin is signalling that it is ready to talk to the incoming US administration. But Trump may find Russia’s terms make him look unacceptably weak.

The nervousness of Ukrainian leadership is understandable. Since Donald Trump’s re-election, Russian President Vladimir Putin has lost no time in preparing the ground for a direct discussion between the US and Russia about the terms for peace in Ukraine – although reports at the weekend that Trump has recently spoken to Putin by phone were swiftly denied by the Kremlin.

Ukrainian President Volodymyr Zelenskyy has made determined efforts in recent months to persuade Trump that Ukraine’s future is worth fighting for. But there is no sign that his messages have brought about a change of heart. 

Trump appears to have no sympathy for Ukraine and no interest in the country – beyond preventing further US commitments to its defence. (Since February 2022, the US has provided $175 billion of economic and military aid to Kyiv, around 7 per cent of total allocated defence spending during that time).

Zelenskyy has genuine reason to fear that Trump might agree to terms whose consequences he does not fully understand.

Trump clearly regards Ukraine as an opportunity to demonstrate his power to US voters. If he can bring Putin to the table and end a war that in his view serves no purpose for the American people, it will also boost his claim that he can prevent World War 3.

Seen from Kyiv, the power relationship works in reverse. Putin is drawing Trump – said to be susceptible to flattery – into a negotiation to resolve an issue of great personal importance to him. The Russian president knows the issues in intimate detail, whereas Zelenskyy has genuine reason to fear that Trump might agree to terms whose consequences he does not fully understand.

Putin’s objectives

Putin has not deviated from his goals stated at the start of the full-scale invasion. These are the demilitarization of Ukraine and the replacement of Zelenskyy and his government by a leadership that accepts Moscow’s diktat (‘denazification’).

Putin’s highest priority for talks will be to ensure Ukraine’s neutrality. This will require a firm commitment that Ukraine will not join NATO in the foreseeable future. He will also seek to restrict the size of Ukrainian armed forces and prevent the stationing of foreign troops on Ukrainian territory. 

Putin will also hope to consolidate Russia’s grip on the Crimean peninsula by winning recognition of his annexation of Ukrainian territory. He will likely demand control of those parts of Donetsk and Luhansk Regions not yet occupied by Russian forces, perhaps trading occupied territories in Kherson and Zaporizhzhia for Ukrainian-held territory in Russia’s Kursk Region.

Lastly, Putin will want sanctions relief. The Russian economy has managed to adapt to US sanctions and reduce their effect, but they are a significant burden on the country’s development. 

The loss of access to Western technology and equipment has halted several major industrial products. If sanctions remain in place, such effects will become more pronounced.

Trump might readily agree to these terms. But to do so without evidence of reciprocal flexibility by Putin will expose him to accusations of naivety and weakness as a negotiator. 

Trump could easily brush aside claims that he was outsmarted by Putin. But a charge that he was a weak negotiator would offend his vanity and damage his image in the view of Chinese policymakers – who will be watching closely. 

It is fair to assume that Trump will want to avoid this perception since he has worked hard to create the impression that China, Iran and others should continue to fear him in his second term.

Putin may therefore need to offer the US a sufficiently large incentive – an outcome that will allow both Washington and Moscow to claim an advantageous agreement. It is not clear what Putin could propose that would be affordable to him and satisfy Trump’s America First agenda. 

Ukrainian hopes

Shortly before the election, Trump spoke of the need to ‘un-unite’ Russia and China. The idea that Putin could help Washington by turning away from China is fantastical.

One consolation for Ukrainians is that the Kremlin was disappointed by Trump during his first term since despite his friendly signals, no major results were achieved.

The relationship between Beijing and Moscow is far more complex than it appears on the surface. But the two share the common strategic goal of reducing the global influence of the US and its allies and have established much deeper relations since Trump left office in 2020.

It is also hard to see a new arms control proposal coming from Moscow that would interest Trump. The hope in Kyiv is that Trump will quickly recognize that the deal he would like to strike will not materialize because the underlying and connected issues – such as Russia–China relations – are more complex than he imagines. 

The one consolation for Ukrainians is that the Kremlin was disappointed by Trump during his first term, since despite his friendly signals no major results were achieved. The Trump administration supplied anti-tank weapons to Ukraine and fiercely opposed the building of the Nord Stream 2 gas pipeline connecting Russia and Germany.

Who Trump listens to

While Trump’s approach to negotiating with Moscow is likely to be highly personal and idiosyncratic, the preparation of talks will depend heavily on those he appoints to key positions. At this stage, it is unclear who in the new administration will be responsible for coordinating Russia policy and to what extent they might challenge Trump’s thinking.

The UK's new Online Safety Bill

The UK's new Online Safety Bill 10 February 2021 — 3:00PM TO 3:45PM Anonymous (not verified) 26 January 2021 Online

Discussing the new proposals which include the establishment of a new ‘duty of care’ on companies to ensure they have robust systems in place to keep their users safe.

Governments, regulators and tech companies are currently grappling with the challenge of how to promote an open and vibrant internet at the same time as tackling harmful activity online, including the spread of hateful content, terrorist propaganda, and the conduct of cyberbullying, child sexual exploitation and abuse.

The UK government’s Online Harms proposals include the establishment of a new ‘duty of care’ on companies to ensure they have robust systems in place to keep their users safe. Compliance with this new duty will be overseen by an independent regulator.

On 15 December 2020, DCMS and the Home Office published the full UK government response, setting out the intended policy positions for the regulatory framework, and confirming Ofcom as the regulator.

With the legislation likely to be introduced early this year, the panel will discuss questions including:

  • How to strike the balance between freedom of expression and protecting adults from harmful material?

  • How to ensure the legislation’s approach to harm is sufficiently future-proofed so new trends and harms are covered as they emerge?

  • What additional responsibilities will tech companies have under the new regulation?

  • Will the regulator have sufficient powers to tackle the wide range of harms in question?

This event is invite-only for participants, but you can watch the livestream of the discussion on this page at 15.00 GMT on Wednesday 10 February.

Persuasion or manipulation? Limiting campaigning online

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.

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.

The regional and international implications of restrictions to online freedom of expression in Asia

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.

Battle lines being drawn over online freedoms in Asia

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.

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.
