Despite its major importance in human health, the metabolic potential of the human gut microbiota is still poorly understood. We have recently shown that biosynthesis of Ruminococcin C (RumC), a novel ribosomally synthesized and posttranslationally modified peptide (RiPP) produced by the commensal bacterium Ruminococcus gnavus, requires two radical SAM enzymes (RumMC1 and RumMC2) catalyzing the formation of four Cα-thioether bridges. These bridges, which are essential for RumC's antibiotic properties against human pathogens such as Clostridium perfringens, define two hairpin domains giving this sactipeptide (sulfur-to-α-carbon thioether–containing peptide) an unusual architecture among natural products. We report here the biochemical and spectroscopic characterizations of RumMC2. EPR spectroscopy and mutagenesis data support that RumMC2 is a member of the large family of SPASM domain radical SAM enzymes characterized by the presence of three [4Fe-4S] clusters. We also demonstrate that this enzyme initiates its reaction by Cα H-atom abstraction and is able to catalyze the formation of nonnatural thioether bonds in engineered peptide substrates. Unexpectedly, our data support the formation of a ketoimine rather than an α,β-dehydro-amino acid intermediate during Cα-thioether bridge LC–MS/MS fragmentation. Finally, we explored the roles of the leader peptide and of the RiPP precursor peptide recognition element, present in myriad RiPP-modifying enzymes. Collectively, our data support a more complex role for the peptide recognition element and the core peptide for the installation of posttranslational modifications in RiPPs than previously anticipated and suggest a possible reaction intermediate for thioether bond formation.

Leukocidin ED (LukED) is a pore-forming toxin produced by Staphylococcus aureus, which lyses host cells and promotes virulence of the bacteria. LukED enables S. aureus to acquire iron by lysing erythrocytes, which depends on targeting the host receptor Duffy antigen receptor for chemokines (DARC). The toxin also targets DARC on the endothelium, contributing to the lethality observed during bloodstream infection in mice. LukED is comprised of two monomers: LukE and LukD. LukE binds to DARC and facilitates hemolysis, but the closely related Panton–Valentine leukocidin S (LukS-PV) does not bind to DARC and is not hemolytic. The interaction of LukE with DARC and the role this plays in hemolysis are incompletely characterized. To determine the domain(s) of LukE that are critical for DARC binding, we studied the hemolytic function of LukE–LukS-PV chimeras, in which areas of sequence divergence (divergence regions, or DRs) were swapped between the toxins. We found that two regions of LukE's rim domain contribute to hemolysis, namely residues 57–75 (DR1) and residues 182–196 (DR4). Interestingly, LukE DR1 is sufficient to render LukS-PV capable of DARC binding and hemolysis. Further, LukE, by binding DARC through DR1, promotes the recruitment of LukD to erythrocytes, likely by facilitating LukED oligomer formation. Finally, we show that LukE targets murine Darc through DR1 in vivo to cause host lethality. These findings expand our biochemical understanding of the LukE–DARC interaction and the role that this toxin-receptor pair plays in S. aureus pathophysiology.

Lys234 is one of the residues present in class A β-lactamases that is under selective pressure due to antibiotic use. Located adjacent to proton shuttle residue Ser130, it is suggested to play a role in proton transfer during catalysis of the antibiotics. The mechanism underpinning how substitutions in this position modulate inhibitor efficiency and substrate specificity leading to drug resistance is unclear. The K234R substitution identified in several inhibitor-resistant β-lactamase variants is associated with decreased potency of the inhibitor clavulanic acid, which is used in combination with amoxicillin to overcome β-lactamase–mediated antibiotic resistance. Here we show that for CTX-M-14 β-lactamase, whereas Lys234 is required for hydrolysis of cephalosporins such as cefotaxime, either lysine or arginine is sufficient for hydrolysis of ampicillin. Further, by determining the acylation and deacylation rates for cefotaxime hydrolysis, we show that both rates are fast, and neither is rate-limiting. The K234R substitution causes a 1500-fold decrease in the cefotaxime acylation rate but a 5-fold increase in kcat for ampicillin, suggesting that the K234R enzyme is a good penicillinase but a poor cephalosporinase due to slow acylation. Structural results suggest that the slow acylation by the K234R enzyme is due to a conformational change in Ser130, and this change also leads to decreased inhibition potency of clavulanic acid. Because other inhibitor resistance mutations also act through changes at Ser130 and such changes drastically reduce cephalosporin but not penicillin hydrolysis, we suggest that clavulanic acid paired with an oxyimino-cephalosporin rather than penicillin would impede the evolution of resistance.

Wisdom to my mind is a bit of a paradox. It is subjective and context-dependent, but inherently universal. I say this, because for something to be wise it ought to be applicable across time and space, yet whether the claims are appraised as being “wise” hinges on the perception of a past, present or future audience. It is beyond the self, yet dependent upon the self. So that then begs the fantasy writing question: What if the self is not human? If culture already morphs the form and substance of wisdom, what effect might a different state of being have on it?

That would be terribly dull to prescribe, but I can help get some readers’ creativity going. Below I have listed relevant questions with examples you might consider when building your setting, so you may merrily thread into your fantastic realms to shape oddities rich and strange.

I would advise readers of this article to try and let go of their own presumptions on what is wise for the sake of worldbuilding. There are few cultures in our modern, human world whose philosophers deem obtuse narcissists dressed in mink robes as being wise, but why wouldn’t a race of bobcat-folk?

G20's lack of progress highlights challenge for COP26 Expert comment NCapeling 1 November 2021

A positive outcome from the G20 summit was committing to end international financing for coal projects but, on other issues, the communique was ultimately weak.

Success at Glasgow depends on bridging fault lines

Renata Dwan

The G20 summit’s lack of progress on climate highlights the scale of the challenge – and the stakes – for COP26.  The countries responsible for 80 per cent of global emissions recognized but failed to agree concrete action to limit global warming to 1.5C.

The leaders’ gathering reveals multilateralism’s fault lines. One is the tension between domestic politics and international priorities, reflected in the lack of ambition to reduce coal dependency.  The second is the tension between industrialized and developing states over responsibility for delivering global goods.

The G20 failed to endorse the G7’s pledge to achieve net zero emissions by 2050 or to accelerate the mobilization of previously agreed climate financing. Success at Glasgow – and beyond – will depend on the extent to which these fault lines can be bridged.

Communique’s language was weak

Professor Tim Benton

A positive outcome on climate from the G20 summit was the commitment to end international financing for coal projects by the end of 2021. This is a win for the climate and for the G20-host, Italy.

The references to 1.5 degrees and the commitment to taking further action this decade were also important, and help lay the groundwork for COP26. On the downside, the communique’s language on phasing out fossil fuel subsidies and coal domestically was very weak.

The G20 summit should be regarded as the next step – it is crucial world leaders accelerate their efforts at COP26 in Glasgow to avert climate catastrophe and keep 1.5 degrees alive.

Platitudes and vague plans on pandemic preparedness

Robert Yates

As G20 leaders head to Glasgow to tackle the evolving climate crisis, they leave Rome having failed, yet again, to take serious action to end the ongoing COVID-19 crisis.

Despite the obvious urgency to achieve universal vaccine coverage, their communique contains little more than platitudes and vague plans to prepare better for future pandemics. It is not as if they had not been briefed. 

In the run up to the G20, the leaders of the WHO, WTO, IMF, World Bank, former world leaders, Nobel laureates and the Pope, all highlighted the costs of ongoing vaccine inequity: five million deaths next year and $5.3 trillion dollars in lost economic output by 2026.

The ask was also straightforward: launch a massive airlift of unneeded vaccines from rich countries through COVAX, ramp up financing of the multilateral response and accelerate technology transfers to developing countries.

But on all these issues the wording of the communique is weak, with no numbers on vaccines or funding, no hard timescales and no urgency. This does not augur well for the COP-26 summit.

G20 communique is a launching pad

Dr Leslie Vinjamuri

The G20 might seem disappointing to some, but a lot will depend on expectations. If your starting point is a pandemic that has so far taken five million lives and driven a global economic crisis, and that both these crises are marked by deep inequality, then the measures adopted are bound to look insufficient. But if your starting point is 16 years of democracy in decline, rampant disinformation on issues of climate and public health, four years of failed international leadership during the Donald Trump presidency and, especially today, heightened tensions between the US and China, the world’s two greatest powers, then the fact that the G20 communique achieved as much as it has is remarkable.

Any written document that requires agreement between the US, UK, China, Russia, India, Saudi Arabia and the EU is necessarily going to be watered down.

But the principles are in the document, and mostly everyone turned up – if some by video. That is a good outcome for this kind of multilateralism in 2021. The G20 communique is a floor not a ceiling, and it’s a launching pad for activism and mobilisation by individual states, but also by corporates, civil society, and subnational actors. 

Now we need to hope that those on the right side of progress, whether on climate, health, or development, will use this language to drive forward concrete actions towards net zero, climate finance, vaccine distribution, and debt relief.

Specifics are for the most part missing

Creon Butler

This year’s G20 leaders’ summit marks a stark contrast with the past four years when much of the group’s energy was exhausted simply trying to maintain a consensus – in the face of opposition by a President Trump-led United States – on such issues as the importance of tackling climate change, the benefits of the rules-based multilateral trade system and the centrality of the International Monetary Fund (IMF) in the global financial safety net. 

By contrast, today’s G20 Rome Leaders’ declaration early on underlines ‘the crucial role of multilateralism in finding shared, effective solutions’. In two critical areas for the world economy – the global boost to liquidity from the general allocation of $650bn in Special Drawing Rights and the global tax deal focused on addressing challenges arising from digitalisation – this outlook has been translated into very substantial and concrete achievements announced earlier in the year.

Europe should become the top priority for Liz Truss Expert comment NCapeling 3 September 2022

Liz Truss has the chance to be a better prime minister than Boris Johnson was, not least in the UK’s foreign policy.

For all the smoke-and-mirrors talk now commonplace about Brexit opportunities, there is real potential that Liz Truss could extract from the aftermath of that upheaval as well as from the turmoil in the world.

But the approach and priorities she revealed during her one year as a better UK foreign secretary than Boris Johnson was – although he did set a low bar – as well as the past three months campaigning for the leadership of her party contain a warning.

She has shown a willingness to aggravate relationships with allies in pursuit of the support of her party faithful, and of a vision of British independence as well as a tendency to dismiss economic analysis when it inconveniently questions her assertions about favoured policies.

At the heart of her political identity is a notion which is both a strength and a potentially calamitous weakness – a love of the notion of being a disrupter which injects a deliberate unpredictability into her approach towards a world in extreme flux.

If she indulges this without good judgment, she could do real damage to Britain’s prospects and standing in the world.

Ukraine and the energy crisis

In foreign policy, Europe should be her starting point and the opportunity here for the UK is clear. The war in Ukraine and crisis in the cost of energy gives it a role – despite having left the European Union (EU) – in talking to EU governments about the future of the continent on many fronts.

Johnson’s emphatic support of President Zelensky gave the UK a position of moral and strategic clarity which Truss can build on through what will be an exceptionally difficult winter for Europe’s governments.

She is in a position to persuade European leaders to remain united in Ukraine’s support while planning better how they are going to source energy. She could expand on that to help the EU find a way through its many other problems, such as upholding democratic values throughout the bloc or finding a response to migration.

There is also a chance for the UK to shape Europe’s thinking on the development and regulation of digital technology and medicine, energy, and the environment.

Truss’s declaration that the UK should now spend three per cent of its GDP on defence could help her in taking that kind of role. However this campaign declaration is not yet credible, given the pressures on the national finances and her silence so far on support for households on energy costs.

But that is the opportunity in theory and the signs are this is not her approach to Europe. Her provocative and opportunistic comment that the ‘jury’s out’ on whether President Macron (and France) was a friend or foe shocked both Britain’s allies and opponents.

For those keen to see divisions among democracies, it gave unexpected, heady encouragement, and to those within those countries, it injected a doubt about shared values which was deeply damaging. The chilly poise of Macron’s response – that the UK and France would always be allies – showed how far she had departed from normal protocol.

The episode encapsulated one of the sources of unease about the Truss style – improvisation under the banner of ‘disruption’ without thought of consequences.

However, she has shown consistency over the Northern Ireland Protocol with little sign of compromise, and that alone could cause much unnecessary damage to UK interests. It also puts her on a collision course with the EU and the UK House of Lords, due to consider controversial legislation again in early October after the Conservative party conference.

There is huge opposition in the Lords to two aspects of the legislation. The first target is the intention of the Johnson government – likely to be repeated by a Truss government – to use the bill to jettison aspects of the protocol, which many argue breaks international law. The second is the delegated power the bill would give ministers.

The cost of a new, serious clash – or worse, a full trade war – with the EU is high. There is the loss of trade, the increase in friction for business, which is consistently underestimated by the UK government, and the loss of scientific and research partnerships.

More than that, though, there is the weakening of ties to a set of allies with common values sharing an increasingly troubled neighbourhood.

US, China, and others remain important

And to say Europe should come first is not to dismiss other claims on the UK’s foreign policy. Her instinctive liking for the US will help Truss in relations with Washington at a difficult time, and her apparent intention to designate China as ‘a threat’ will support that relationship too.

Independent Thinking: Western tanks head for Ukraine Audio NCapeling 26 January 2023

Episode 12 of our weekly podcast analyses the deployment of international battle tanks to Ukraine and the contentious diplomacy putting pressure on Germany.

The panel examines what kind of capabilities will new weapons give to Ukraine amid fears of a new Russian offensive looming in the spring, and the intense pressure Olaf Scholz’s German government has been under since the invasion of Ukraine started.

How has Germany’s standing changed over the past 12 months, and what are the challenges facing the country in its relations with Russia as a long and cold winter sets in?   

Joining Bronwen Maddox this week from Chatham House are Orysia Lutsevych, head of the Ukraine Forum, and Marion Messmer, senior research fellow in the International Security programme, along with Jeremy Cliffe, writer-at-large for The New Statesman magazine, and Ed Arnold, research fellow for European security at the Royal United Services Institute (RUSI).

Health not independence is focus for Sturgeon successor Expert comment NCapeling 15 February 2023

Nicola Sturgeon’s star may have been fading, but Rishi Sunak and Keir Starmer will be relieved at the exit of one of the UK’s most influential politicians.

Nicola Sturgeon has left at the right time, maybe even a bit late. Although one of the most influential politicians the UK has seen in recent times, she was also one of the most divisive.

Her ability to fan Scotland’s sense of difference from England brought new hope to the independence movement, but this cause – by which she measured herself above all others – has been losing ground and for now, looks to be in abeyance.

Neat and disciplined, Sturgeon could not have presented a greater contrast to Boris Johnson in the first months of the pandemic. That was one of her finest moments.

She used the powers of the devolved government to make different lockdown decisions for Scotland – never all that different from those in England but often announced just a few hours earlier.

Although analysts surmise that these made little difference to the death rate – although poverty and other health support factors make comparisons hard – she used the platform, with the cameras on her, to ram home the point that Scotland could set its own rules.

Rallying young voters to independence

Her second greatest moment was in the aftermath of Brexit. Scots voted overwhelmingly to stay in the European Union (EU) and so, she argued, they should have the right to leave the UK to join that other union. Younger voters in particular responded, rallying to the independence cause.

But two recent setbacks showed her star was fading. She lost the Supreme Court battle to hold a second independence referendum in November, when she was told Scotland simply did not have the powers to hold one on its own if Westminster said no – and the UK government did just that. It was hard to see how her campaign for independence could move forwards.

And her planned reforms to the gender recognition process in Scotland have been blocked by the UK government – but unease about her reforms within Scotland meant this rebuff did not win her the support at home she hoped for. She was also accused of playing politics by pressing ahead with unpopular reforms simply because of their potential to discomfit the UK government.

Health, education, and public services need attention

Other challenges were also building up and, even if less eye-catching, her successor is likely to focus on health and education above the birth of a new nation. Sturgeon’s critics have long argued that under Scottish National Party rule, health, education, and other public services have declined.

In elections, these factors can be eclipsed by passions about independence but it is rare in political life for a leader to be insulated from public anger on this front. This is almost certainly where her successor will want to focus first.

Alzheimer's disease (AD) is characterized by neuronal loss and accumulation of β-amyloid-protein (Aβ) in the brain parenchyma. Sleep impairment is associated with AD and affects about 25–40% of patients in the mild-to-moderate stages of the disease. Sleep deprivation leads to increased Aβ production; however, its mechanism remains largely unknown. We hypothesized that the increase in core body temperature induced by sleep deprivation may promote Aβ production. Here, we report temperature-dependent regulation of Aβ production. We found that an increase in temperature, from 37 °C to 39 °C, significantly increased Aβ production in amyloid precursor protein-overexpressing cells. We also found that high temperature (39 °C) significantly increased the expression levels of heat shock protein 90 (Hsp90) and the C-terminal fragment of presenilin 1 (PS1-CTF) and promoted γ-secretase complex formation. Interestingly, Hsp90 was associated with the components of the premature γ-secretase complex, anterior pharynx-defective-1 (APH-1), and nicastrin (NCT) but was not associated with PS1-CTF or presenilin enhancer-2. Hsp90 knockdown abolished the increased level of Aβ production and the increased formation of the γ-secretase complex at high temperature in culture. Furthermore, with in vivo experiments, we observed increases in the levels of Hsp90, PS1-CTF, NCT, and the γ-secretase complex in the cortex of mice housed at higher room temperature (30 °C) compared with those housed at standard room temperature (23 °C). Our results suggest that high temperature regulates Aβ production by modulating γ-secretase complex formation through the binding of Hsp90 to NCT/APH-1.

What the US election means for trade policy Expert comment LJefferson 10 October 2024

Kamala Harris and Donald Trump could not be more different when it comes to trade, despite a changed economic landscape.

Trade policy is playing a relatively subdued role in this autumn’s US election. Yes, former president Trump has proposed tariffs of anywhere from 20 per cent to 100 per cent, asserting the revenue could fund policy areas from deficit reduction to childcare, all while growing US employment and promoting world peace.
  
But unlike 2020, or even more 2016, the international trade architecture has not been a lively part of this year’s campaign. The two parties now start from a shared expectation of an international economic landscape shaped more by competition and industrial policy than by continued liberalization. However, the two presidential candidates’ views of which trade tools to use, and whether to proceed with allies and partners or unilaterally, could not be more different.

New set of trade expectations

A large part of the relative calm has to do with the emergence of a new set of expectations on trade that are shared across Republicans and Democrats, and that are unlikely to shift in the next four years regardless of who occupies the White House.

First, neither party can field the support to pass a traditional comprehensive free trade agreement through Congress. While each party still has a wing of elected officials who would like to see the US return to negotiating deals like the Trans-Pacific Partnership, or attempt expansive new deals with Europe or in the Western Hemisphere, they are unlikely to reach critical mass in the immediate future, regardless of who holds the White House – or who controls Congress.

This shift in perception of the relative value of such deals – and their potential to cause political blowback for legislators – also means that the cost to any administration that wanted to propose such a deal would be high.

Second, there is broad bipartisan support to continue measures aimed at promoting US security in the face of high-technology challenges from Beijing that have both military and security applications. This means continued US activism in export controls and other more innovative measures.

Less divergence on clean energy

While there is also cross-party enthusiasm for approaches to building up US manufacturing that fall under the rubric of industrial policy, the parties diverge significantly when it comes to specific content. However, around clean energy that divergence will be less than the campaign trail rhetoric suggests.

Because clean energy generation is spread so broadly across the United States – with a great deal of wind and solar generation in Republican-governed ‘red states,’ and investment from the Inflation Reduction Act flowing to red states as much or more than blue ones – such incentives, and their effects on trade policy, are here to stay. Despite this, a Republican presidency or Congress will certainly seek to water down or eliminate parts of the Inflation Reduction Act that focus specifically on transition away from fossil fuels.
 
Coupled with this commitment to making America a clean energy superpower, there is considerable cross-party interest in trade initiatives that promote clean energy and manufacturing – whether from a climate perspective or a pure economic competitiveness perspective. A wide range of creative proposals are buzzing around Congress and think-tanks – from a carbon border measure, to resuscitating the Global Steel Arrangement, to critical mineral-focused deals. Though the topic is often overlooked in overviews of trade policy, it is the one where we are most likely to see classic trade tools used.

A vast difference between the two candidates

Beyond those broad strokes of an emerging ‘new Washington consensus,’ as former US trade representative and current head of the Council on Foreign Relations Michael Froman describes it: who wins the presidency will make a vast difference in what Washington does on trade – and how it aims to achieve its goals.

A Harris administration will aim to develop shared economic security agendas with allies and partners – quite possibly expanding beyond the Biden Administration’s G7 focus to pursue more deals with a broader range of partners. Trump, on the other hand, has explicitly said he will pursue US economic interests at the expense of allies and partners. ‘Under my leadership,’ he said in a speech in Georgia last month, ‘we’re going to take other countries’ jobs,’ specifically citing allies Germany and South Korea as targets.

While Vice-President Harris has criticized Trump’s tariff proposals, and noted their likely negative effects on consumers, she has not signalled that she would make changes to the tariffs on China first imposed by President Trump and then adjusted by President Biden. 
A Trump administration would use tariffs aggressively, but it remains absolutely unclear how. 

What are the top economic priorities for the new US President? 19 November 2024 — 8:00AM TO 9:15AM Anonymous (not verified) 15 October 2024 Chatham House

A post-US election discussion on the outlook for US economic policy and implications for the global economy.

A fortnight on from the US Presidential and Congressional elections, this expert panel, organised by Chatham House’s Global Economy and Finance Programme in collaboration with the Society of Professional Economists, will consider the outlook for US economic policy and implications for the global economy.

Questions for discussion will include:

• What will the economic priorities of the new President be? What will be the role of industrial strategy/green transition, regulation, trade, migration and fiscal policy?
• How far will the President be constrained by other branches of the US government, including Congress, the courts and state governments?
• What will the implications be for the global economy broadly and through the specific channels of trade, investment, monetary policy and debt?
• How will the new President handle economic and financial relations with the US’s traditional G7 allies, China and the Global South?

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.

The US election could create the need for a G7 alternative – without American representation Expert comment jon.wallace 15 October 2024

Traditional allies of the US need to find a way to work together on some global policy issues even when the US itself is not engaged. A ‘G6 plus’ group could provide an answer.

When Jamaica pulled out of the nascent West Indies Federation in 1961, Trinidad and Tobago’s then prime minister, Dr Eric Williams, famously said ‘One from ten leaves nought’. In the run up to the US elections on 5 November, the US’s longstanding allies need to ask themselves if the same logic must apply to the G7. 

A Donald Trump victory will result in stark differences between the US and its closest partners on key global economic issues. US allies would no doubt try and persuade the new president to moderate his position, but experience suggests that this will have little, if any, effect.  

They may then want to work around the US, or on a parallel track. But doing so will be very hard unless they have a framework for discussing and developing ideas collectively. Could some form of ‘G6 plus’ forum help?

The role of the G7 today

The G7 no longer acts as a steering group for the global economy. However, it remains a critical forum for the US and its allies to coordinate their efforts to help solve global problems, to defend common Western interests, to resolve internal disputes and to underpin information exchange. 

In the past two years, the G7 has come to be seen by the US and other members as one of the most effective international mechanisms. It has played a critical role coordinating Western efforts to recover from the last pandemic and prepare for future ones.  

It has been pivotal in weakening Russia’s economy following the attack on Ukraine and has acted to strengthen Western economic security and resilience more broadly.  

The G7 has also responded to ‘Global South’ calls for help in dealing with the pandemic aftermath and the Ukraine war. 

Trump’s approach to the G7

The problem is that the G7’s effectiveness depends critically on full US engagement, sometimes as a leader of initiatives (such as the decision to impose an ‘oil price cap’ on Russia in autumn 2022) or as an essential partner. 

If elected, former President Trump is likely to abandon the G7 as an instrument of international economic policy. This is effectively what happened during his first presidency and there are reasons to expect this to be repeated. 

Many of Trump’s international economic policies are highly controversial with US allies, including his apparent determination to withdraw from the Paris Agreement, impose across the board 10-20 per cent tariffs and even punish countries for not using the dollar. His domestic policies, including mass deportation of undocumented immigrants and aggressive deregulation and fiscal easing could lead to further sharp disagreements.  

Furthermore, Trump demonstrates general antipathy towards multilateralism. Under his presidency, US representatives in the G7 and G20 sought to weaken core values and policies that have underpinned international economic cooperation for decades – including the importance of a rules based international system, the IMF’s global safety net role, and the responsibility of the advanced world to assist the poorest countries financially.  

Other G7 and G20 countries tried to preserve as much as possible of the previous consensus. But in the case of climate change, the only solution was to have a separate text for the US. Critically, such efforts diverted time and attention from the enormous challenges facing the world at the time. 

Trump went through four different G7/G20 Sherpas during his presidency and disowned the final declaration of the 2018 Canadian G7 summit after hundreds of hours of negotiation, and despite previously signing off on the text. The US failed to host a final leaders’ summit, even virtually, during his administration’s G7 presidency.  

Of course, how far Trump carries through his most radical policies will depend, among other things, on the outcome of the Congressional elections and the stance taken by US courts. 

He may also have second thoughts if elected. His first administration sometimes supported significant multilateral economic initiatives, notably the G20’s Debt Service Suspension Initiative and ‘Common Framework’ for debt rescheduling. 

But, in the event of a second Trump administration, the most likely scenario for the G7 is a repeat of the paralysis of 2017-20, which would be even more costly today.

Should Vice President Kamala Harris win on 5 November, the situation should in theory be very different. She will likely continue with President Joe Biden’s collaborative approach to the G7.

Nonetheless, major issues may still arise where America’s allies want to take a fundamentally different approach and need a mechanism to do so. These could include policy on the WTO, de-risking the economic relationship with China, restricting carbon leakage, and regulating US-dominated big tech.  

How should US allies respond?

No US ally will want to be seen to be leading development of a new ‘G6’ that excludes the US. The top priority will be securing the best possible relationship with the incoming president. Political weakness and/or new governments in France, Germany, the UK and Japan will add to this hesitancy.

Any new forum will therefore need to be as low profile as possible. The concept should initially be discussed in private by sherpas from each participating country. Once established, officials should as far as possible meet online. Leaders should only meet online, at least initially.  

Participants should be fully transparent about the forum’s existence and avoid any grand ‘framing’ along the lines of the EU’s ‘strategic autonomy’. Instead, it should be described as a practical, largely technocratic forum intended to coordinate activity among Western economic powers in those areas where the US chooses not to engage. A suitably innocuous name – such as the ‘the sustainable growth club’ could help.

Topics should be limited to those requiring urgent collective global action, such as climate, health, tech governance, development finance and trade – and where the US federal government is not an ‘essential’ partner. Such a forum should not therefore address defence.  

Resetting Africa-Europe relations: From self-deception to economic transformation 28 October 2024 — 12:30PM TO 1:30PM Anonymous (not verified) 16 October 2024 Chatham House and Online

Experts assess the status of ties between Africa and Europe in a rapidly changing world, launching a new book that explores how misconceptions in the relationship can harm Africa’s economic agenda.

The relationship between Africa and Europe has long been shaped by colonial legacies, power imbalance and shifting geopolitical interests.

Almost three years on from the last EU-AU summit in Brussels in February 2022, questions remain over the delivery of headline commitments under the continent-to-continent partnership – ranging from the EU’s Global Gateway infrastructure strategy to wider climate financing promises.

As Africa seeks to strengthen its standing on the global stage, marked by the African Union’s upcoming debut at the G20 summit in November, a critical reassessment of these dynamics is needed to examine whether the continent’s relationship with Europe can overcome stigmatized narratives in search of genuine economic benefit.

At this event, which launches a new book by Professor Carlos Lopes: The Self-Deception Trap: Exploring the Economic Dimensions of Charity Dependency within Africa-Europe Relations, speakers assess the prospects for a transformative shift towards a more equitable and mutually beneficial Africa-Europe partnership.

Evolving Turkey–Iran relations and implications for regional reordering

This project examines the nature of the bilateral relationship between Turkey and Iran in relation to Middle Eastern countries and in the context of broader regional dynamics.

The 2016–21 period in Turkish–Iranian relations, which was marked by both sides’ structured cooperation through the Astana Process and Sochi summits on conflict management in Syria, and their largely shared opposition to US policy in Syria and at the broader regional level, to Iraqi Kurdistan’s independence referendum, and to the blockade of Qatar, has run its course. 

However, the new shape of these bilateral relations remains undefined, and understanding them is essential to effective policymaking in the region. How they will evolve will have direct ramifications for Iraq, Syria, regional Kurdish geopolitics, and the process of regional reordering and connectivity in the Middle East and South Caucasus. They will also have direct implications for US and European policymaking and role in the region. 

This project studies the evolving nature of Turkish–Iranian relations through Iraq, Syria and regional Kurdish politics. It examines how Turkey and Iran approach regional connectivity projects and major regional initiatives, and how ongoing regional developments, including the war in Gaza, have and may impact Turkey–Iran relations and EU, US and UK security considerations and policy towards the two countries.

The Centre for Applied Turkey Studies (CATS) at the Stiftung Wissenschaft und Politik (SWP) in Berlin is funded by Stiftung Mercator and the Federal Foreign Office. CATS is the curator of the CATS Network, an international network of think-tanks and research institutions working on Turkey.

Addressing Russia’s use of forced displacement in Ukraine 7 November 2024 — 12:30PM TO 2:00PM Anonymous (not verified) 17 October 2024 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 Democratic Republic of the Congo’s foreign policy priorities 29 October 2024 — 1:00PM TO 2:00PM Anonymous (not verified) 18 October 2024 Chatham House and Online

The DRC’s Minister of Foreign Affairs discusses the country’s approach to regional stability and the role of international partnerships in securing economic prosperity.

At this event, HE Thérèse Kayikwamba Wagner, Minister of Foreign Affairs of the DRC, will discuss DRC’s regional diplomatic priorities and international agency, including its ambitions around global critical mineral supply chains.

The Democratic Republic of the Congo (DRC) faces foreign policy tests as it manages a complex security crisis and regional tensions, alongside global economic and trade partnerships.

Entrenched conflict in eastern DRC continues to have wider regional implications. Troops from the Southern African Development Community (SADC) deployment are tackling a growing mandate as the UN’s peacekeeping mission prepares to withdraw. Tensions with Rwanda also remain high despite mediation efforts under the Luanda process.

As a major producer of critical minerals for the global energy transition, the DRC seeks to benefit from growing international demand without sacrificing value addition. New and existing frameworks with international partners will remain key to this vision, including for the development of regional infrastructure networks such as the Lobito Corridor.

At this event, HE Thérèse Kayikwamba Wagner, Minister of Foreign Affairs of the DRC, will discuss the DRC’s regional diplomacy and international agency, including the country’s positioning in global critical mineral supply chains.

Please note that in-person attendance for this event will be balloted. Guests looking to join in-person must register interest in joining. Full confirmations to successful applicants will be sent on Friday 25 October.
