AAA+ ATPases constitute a large family of proteins that are involved in a plethora of cellular processes including DNA disassembly, protein degradation and protein complex disassembly. They typically form a hexametric ring-shaped structure with six subunits in a (pseudo) 6-fold symmetry. In a subset of AAA+ ATPases that facilitate protein unfolding and degradation, six subunits cooperate to translocate protein substrates through a central pore in the ring. The number and type of nucleotides in an AAA+ ATPase hexamer is inherently linked to the mechanism that underlies cooperation among subunits and couples ATP hydrolysis with substrate translocation. We conducted a native MS study of a monodispersed form of PAN, an archaeal proteasome AAA+ ATPase, to determine the number of nucleotides bound to each hexamer of the WT protein. We utilized ADP and its analogs (TNP-ADP and mant-ADP), and a nonhydrolyzable ATP analog (AMP-PNP) to study nucleotide site occupancy within the PAN hexamer in ADP- and ATP-binding states, respectively. Throughout all experiments we used a Walker A mutant (PAN^K217A) that is impaired in nucleotide binding as an internal standard to mitigate the effects of residual solvation on mass measurement accuracy and to serve as a reference protein to control for nonspecific nucleotide binding. This approach led to the unambiguous finding that a WT PAN hexamer carried – from expression host – six tightly bound ADP molecules that could be exchanged for ADP and ATP analogs. Although the Walker A mutant did not bind ADP analogs, it did bind AMP-PNP, albeit at multiple stoichiometries. We observed variable levels of hexamer dissociation and an appearance of multimeric species with the over-charged molecular ion distributions across repeated experiments. We posit that these phenomena originated during ESI process at the final stages of ESI droplet evolution.

China's Regions in an Era of Globalization Book sysadmin 14 May 2018

The rise of China has been shaped and driven by its engagement with the global economy. This engagement cannot be understood at the level of national policymaking alone, but requires analysis of the differences in participation in the global economy across China’s regions.

China is a continent-sized economy and society with substantial diversity across its different regions. This book traces the evolution of regional policy in China and its implications in a global context.

Detailed chapters examine the trajectory of what is now becoming known as the Greater Bay Area in southern China, the inland mega-city of Chongqing, and the role of China’s regions in the globally focused Belt and Road Initiative launched by the Chinese government in late 2013.

It will be of interest to practitioners and scholars engaging with contemporary China’s political economy and international relations.

This book is published as part of the Insights series.

Exploring Public International Law and the Rights of Individuals with Chinese Scholars - Part One Other resource sysadmin 29 October 2018

As part of a roundtable series, Chatham House and China University of Political Science and Law (CUPL) jointly organized this four-day meeting at Chatham House for international lawyers to discuss a wide range of issues related to public international law and the rights of individuals.

The specific objectives were to:

• create a platform for Chinese international law academics working on international human rights law issues to present their thinking and exchange ideas with counterparts from outside China;
• build stronger understanding within the wider international law community of intellectual debates taking place in China about the international human rights system and China’s role within it;
• support networking between Chinese and non-Chinese academics working on international human rights and related areas of international law.

The roundtable forms part of a wider Chatham House project exploring China’s impact on the international human rights system and was inspired by early discussions with a burgeoning community of Chinese academics thinking, writing (mainly in Chinese) and teaching about international human rights law.

For China University of Political Science and Law, one of the largest and most prestigious law schools in China and perhaps the only university in the world with an entire faculty of international law, the initiative is part of a drive to forge partnerships beyond China in the international law field.

The roundtable had a total of 22 participants, 10 Chinese (from universities and other academic institutions in Beijing and Shanghai) and 12 non-Chinese (from Australia, Germany, the Netherlands, Switzerland, the United Kingdom and the United States).

All discussions were held in English under the Chatham House Rule.

How Influential Is China in Zimbabwe? Expert comment sysadmin 20 November 2017

A trip to Beijing by Zimbabwe’s military chief was a ‘normal military exchange’, China’s foreign ministry said after the army seized power in Harare. Alex Vines examines the extent of China’s influence in Zimbabwe.

The news that General Constantino Chiwenga had visited China only a few days before the military takeover in Zimbabwe was a coincidence that did not go unnoticed. There was also speculation after China said it was closely watching developments, but stopped short of condemning President Robert Mugabe’s apparent removal from power.

China is Zimbabwe’s fourth-largest trading partner and its largest source of investment - with stakes worth many billions of pounds in everything from agriculture to construction. Zimbabwe is the dependent partner - with China providing the largest market for its exports and much needed support to its fragile economy.

China’s relations with Zimbabwe are deep, starting during the Rhodesian Bush War. Robert Mugabe failed in 1979 to get Soviet backing, so turned to China, which provided his guerrilla fighters with weapons and training. Both countries formally established diplomatic relations at Zimbabwean independence in 1980 and Mugabe visited Beijing as prime minister the following year. He has been a regular visitor since.

For years, Zimbabwe’s officials have tried to play off China against the West, advocating the country’s ‘Look East’ strategy, particularly following the introduction of EU sanctions in 2002. Indeed, a decade ago, Mugabe told a packed rally at the Chinese-built national sports stadium in Harare: ‘We have turned east, where the sun rises, and given our back to the west, where the sun sets.’

China’s military engagement also deepened during Zimbabwe’s ‘Look East’ era. Significant purchases were made, including Hongdu JL-8 jet aircraft, JF-17 Thunder fighter aircraft, vehicles, radar and weapons. However, following a controversy about a shipment of arms in 2008, Beijing decided to list Zimbabwe for ‘limited level’ military trading.

Despite Zimbabwe’s efforts, the ‘Look East’ strategy did not bring the investment flood hoped for and a decade later, in August 2015, Mugabe openly asked for Western re-engagement in his ‘state of the nation’ address.

Now, the reality is that increasingly Chinese and Western interests - particularly those of the UK - have become aligned. Not far from each other in the outer suburbs of Harare, two of the biggest embassies in Zimbabwe are the British and the Chinese. As other embassies scaled down or closed, Beijing’s expanded. Whereas British diplomats were well connected with business, civil society and opposition figures, the Chinese invested in ‘technical support’ of the party of government Zanu-PF, including state security and the presidency. When it came to Zanu-PF politics and factionalism, Chinese diplomats were well connected and insightful and, like their Western colleagues, concerned about stability, a better investment climate and adherence to the rule of law.

President Xi Jinping visited Zimbabwe in 2015 and President Mugabe visited Beijing in January 2017. In public, the Chinese leader said his country is willing to encourage capable companies to invest in Zimbabwe. But in private, the message was that there would be no more loans until Zimbabwe stabilized its economy.

In 2016 trade between the two countries amounted to $1.1 billion, with China the biggest buyer of Zimbabwean tobacco and also importing cotton and various minerals. In return Zimbabwe imported electronics, clothing and other finished products. Chinese state construction firms have also been active, building infrastructure including Zimbabwe’s $100 million National Defence College. And last year China agreed to finance a new 650-seat parliament in Harare.

But Chinese diplomats and many businesses are waiting for better days in Zimbabwe. Some companies have found the investment climate challenging - being burned on diamonds, for example - and have looked for alternative markets. A couple of weeks ago I was in China, attending a meeting on China-Africa relations and Zimbabwe was not mentioned once. Unlike Ethiopia, Sudan, or Angola that are strategic partners, or big markets like Nigeria, Kenya and South Africa, Zimbabwe is far from being Beijing’s new priority.

So, Beijing’s interest is in a better investment climate in Zimbabwe. A clear transitional arrangement resulting in elections for a legitimate government in Harare is as much in Beijing’s interest as London’s.

The ‘Look East’ and the ‘Re-engagement with the West’ strategies have not brought about the confidence and investment that Zimbabwe needs. What Zimbabwe requires is stable and accountable government - then investors from Asia, America and Europe will seriously consider that Zimbabwe has an investment future. This was the message that Mugabe received in Beijing in January. And the one which Zimbabwe’s military chief also was given last week.

Chatham House Primer: Inside China’s government 30 November 2022 — 6:00PM TO 6:45PM Anonymous (not verified) 4 October 2022 Chatham House

How are decisions made in Beijing, across China and where does the CCP fit in?

Still little is known in Western circles about the inner workings of China’s government. In power since 1949, the ruling Chinese Communist Party has evolved over decades to its current embodiment under President Xi Jinping.

The need for a better understanding of China’s government has been heightened, particularly as the country navigates post-COVID troubles, global economic downturns, wars in Europe, climate change and heightened tension with the United States.

This Primer has been prepared to pull back the veil on the Chinese government. Key issues to be tackled include:

• What is the decision-making process in China’s government?

• How is the party–government relationship best explained?

• How has the party evolved in recent years with new forms of governance and leadership?

• How has China’s government evolved in recent years, particularly in a globalized environment?

• A description of the central government–province dynamic?

• How are citizens engaged in the political process?

• What are the major centres of power in the Chinese political system?

• Has the COVID-19 pandemic altered attitudes towards and the operation of government?

As with all Chatham House member events, questions from members drive the conversation.

The future of the Russia-China relationship 9 February 2023 — 6:00PM TO 7:00PM Anonymous (not verified) 26 January 2023 Chatham House and Online

What lies ahead for the ‘unlimited friendship’ between Moscow and Beijing?

Russia’s invasion of Ukraine has raised new questions about the nature of the relationship between Russia and China, with the war seen as having the potential to shift Russia from a close ally to a liability in the eyes of the Chinese government.

This event explores the latest developments in extent of the relationship and interactions between the two: new convergences and divergences, energy links and limitations, declared alliances and private disagreements.

Experts on the panel explore:

• How has the relationship changed since Russia’s 2022 invasion of Ukraine?
• What do the Russian and Chinese people make of the relationship?
• How could a war-weakened Russia be viewed by China?

As with all members events, questions from the audience drive the conversation.

Is China's economy on the rebound? 5 April 2023 — 6:00PM TO 7:00PM Anonymous (not verified) 28 February 2023 Chatham House and Online

Exploring the domestic and international signals from the first annual session of the 14th National People’s Congress.

2022 proved to be a difficult year for China. War, COVID-19 and economic turbulence presented a cocktail of significant challenges for the ruling CCP in China. Having dispensed of the infamous zero-COVID-19 policy, China is apparently back open for business.

On the international front, continued tensions with the West, war in Europe and climate change are just some of the obstacles standing in the way of Chinese economic recovery. 

Domestically, China must find ways to reinvigorate demand and move on from a low of 3 per cent GDP growth in 2022. With a frustrated population, people are also keen to be freed from the shackles of a stream of lockdowns and quarantining.

The in-tray for the 14th National People’s Congress, as it begins its first session, is substantial. The implications, at home and abroad, from its recent summit in Beijing reverberate around the world.

The experts on the panel discuss:

• What has been the true extent of COVID-related damage to China’s economy and wider society?
• What economic scars are visible post-recovery?
• Will there be longer-term implications for China’s economic and diplomatic footprint globally post-COVID? 

As with all member events, questions from the audience drive the conversation.

Central and Eastern Europe become hawkish on China Expert comment LJefferson 16 September 2022

The recent withdrawal of the Baltic countries from the ‘17+1’ format displays changing perceptions of China due to its ambiguity towards the war in Ukraine.

While the Russian invasion of Ukraine only confirmed Central and Eastern Europe’s views of Russia, it is also affecting their relations with China. Although the relationship was already complicated due to unfulfilled Chinese economic promises to CEE countries and growing indications of efforts to influence their domestic politics, China’s support for Russia is pushing Central and Eastern Europeans even further away.

This shift was highlighted, and formalized, recently by several countries in the region leaving the ‘17+1’ format, through which China cooperates with a group of countries from the region. The shifting attitudes towards China will also influence the relationship between the European Union as a whole and China.

A Trojan Horse that never was

When the format was launched in 2012 between 16 CEE countries at the time and China, the countries jumping on board expected a wave of Chinese investment and an opportunity to diversify mostly west-bound trade.

These hopes never fully materialized as Chinese foreign direct investment (FDI) in CEE has been generally lower compared to the rest of Europe and China never became an important export destination for any of the countries. The growing disillusionment and concern about Chinese security threats has led to some of the countries speaking up about the perceived perils of closer cooperation.

The first to withdraw from what had become ‘17+1’ by 2021 was Lithuania, which also took an interest in strengthening ties with Taiwan and allowed it to open a Taiwanese representative office in Vilnius. This triggered a breakdown in the bilateral relations with China. As a retaliatory response, China blocked Lithuanian imports and imports from other EU states containing inputs from Lithuania, leading the EU to launch an official dispute at the WTO.

War in Ukraine

Since the invasion started, CEE countries have been dealing with large numbers of Ukrainian refugees, organizing shipments of military equipment to Ukraine, and at the same time worrying whether they could be next on Russia’s list.

However, the concerns and security environment that these countries face seems to be almost entirely disregarded by China. On the sidelines of the 2022 Winter Olympics in Beijing, Xi and Putin signed the joint communiqué in which China backed Moscow’s demands to reverse NATO borders to the pre-1997 situation, completely disregarding CEE’s security interests.

China’s implicit support for Russia after the invasion has sowed deep mistrust of its respect for the sovereignty of other nations. The Chinese diplomatic apparatus clearly noticed this changing mood among CEE governments and sent a special envoy to eight capitals in April-May tasked with ‘eliminating misunderstandings regarding Russia-Ukraine conflict’.

However, the trip was not particularly successful. The delegation failed to secure high-level meetings, with the most prominent case being the Polish minister of foreign affairs declining to meet Huo Yuzhen, the Chinese Special Councilor for CEEC cooperation. Given that Andrzej Duda, President of Poland, was the only head of an EU state who attended the Beijing Olympics opening ceremony just before the Russian invasion in February, the change in attitudes is clear.

Following the envoy’s visit to the Czech Republic, the Czech parliament’s foreign affairs committee unanimously approved a resolution calling for the country to quit the ‘16+1’ format and the government is expected to act upon it in the near future. Meanwhile, Latvia and Estonia recently jointly announced that they would no longer be participating in the cooperation framework, turning it into ‘14+1’.
