Kyiv, Ukraine – Both Russia and Ukraine depend on Chinese-made components for drones, jamming systems and the fibre optic cable attached to the drones to make them immune to jamming.

If Beijing wanted to end the Russia-Ukraine war, it could do so promptly and singlehandedly by banning the imports, according to one of the pioneers of drone warfare in Ukraine.

“Almost each component is made in China,” Andrey Pronin, who runs a drone school in Kyiv, told Al Jazeera. “China could cut off their side – or ours.”

Beijing supplies Moscow with four-fifths of drones, electronic chips and other dual-purpose goods that end up on the front line, keeping the Russian war machine rolling, according to Ukrainian intelligence.

Ukraine is trying to wean off its reliance on Chinese drones amid Beijing’s restriction of exports, but they still account for a staggering 97 percent of components, according to the Foundation for Defense of Democracies, a think tank in Washington, DC.

United States President Donald Trump hopes that Thursday’s summit with his Chinese counterpart Xi Jinping can change that.

“I’d like China to help us out with Russia,” Trump said on October 24, two days after cancelling his talks with Russian President Vladimir Putin and slapping sanctions on two Russian oil companies.

Trump is scheduled to meet with Xi in South Korea’s Seoul on the sidelines of the Asia-Pacific Economic Cooperation summit. Their last meeting was held in 2019, in Japan’s Osaka.

Zelenskyy hopes meeting will ‘help us all’

Beijing, which has claimed it is officially neutral regarding the war, denies direct involvement in the Russia-Ukraine conflict. But it plays a role as Moscow’s main political and economic backer.

As Beijing seeks to “return” Taiwan to its fold, Moscow is understood by observers to be sharing with the Chinese military information on the use of drones, the vulnerabilities of Western-supplied weaponry and the management of airborne troops.

Meanwhile, amid mounting Western sanctions, Beijing is buying discounted oil, gas and raw materials, paying Moscow tens of billions of dollars a year.

That is the weak spot Ukrainian President Volodymyr Zelenskyy wants Trump to target in talks with Xi.

If Trump manages to “find an understanding with China about the reduction of Russian energy exports”, he said on Monday, “I think it’ll help us all.”

But Trump’s latest Russia sanctions slapped on state-owned oil giant Rosneft and the private Lukoil company could inadvertently strengthen Beijing.

Both companies will be forced to sell their foreign subsidiaries and diminish their role in international projects – namely, in ex-Soviet Central Asia and several African nations, where their place may be taken by Chinese companies.

According to Volodymyr Fesenko, head of the Kyiv-based Penta think tank, Xi’s role in ending the war is pivotal.

“Without the financial support, without the economic cooperation with China, Russia can’t continue the war,” he said. “China is Russia’s main economic resource.

“Had [Beijing] wanted to end this war, it would have achieved it very fast,” he added. “China’s harsh position in closed-door, non-public talks with Putin would be enough.”

However, Beijing has “no inclination or interest in making a gift to Trump”, said Fesenko.

During his first presidency, ties with Beijing spiralled as the White House sought to curb China’s growing global clout and its access to Western technologies.

China and the US have introduced tariffs on mutual exports as Beijing threatened to cut off the trade in critical minerals, and Washington promised to curb the transfer of technologies. The Russia-Ukraine war is unlikely to dominate the summit, as Trump and Xi have bigger fish to fry as their nations now face a trade war.

‘Freezing the war’

At the same time, Beijing has been boosting its economic clout in Eastern Europe, Moscow’s former stomping ground, investing heavily in new infrastructure.

“The escalation of the war, its spread to Europe, is something that contradicts China’s interests,” Fesenko said.

However, Washington and Beijing may want to keep the war simmering or frozen without letting Moscow or Kyiv win a decisive victory, argued Kyiv-based analyst Igar Tyshkevych.

Washington is not going to benefit from Russia’s “overwhelming victory” as the Kremlin will undoubtedly seek the role of a “third global leader”, he said.

But neither Beijing or Washington could benefit from Russia’s full defeat, as China is concerned by destabilisation near its northern and northwestern borders.

“Washington is active about freezing the war,” Tyshkevych said. “I won’t be surprised if Beijing will be active in the same direction.”

If frozen, there are fears that the war could reignite when Russia recovers economically and accumulates enough resources.

To avoid that, Kyiv would look to building new or strengthening existing partnerships, especially with the European Union and its individual members, as well as countries such as Turkiye and Pakistan that both have cordial ties with Beijing.

And Putin still has plenty of incentives to offer to Trump.

There is a reported proposal to create infrastructure for the Arctic sea route that will shorten the delivery of goods from Asia to Europe by weeks.

Moscow also considered a joint project to sell Russian natural gas to Europe, develop oil and gas fields in Russia’s Far East, and supply rare earths that are crucial for US tech giants.

In a post-war environment, Putin may also propose Russia’s expertise in processing spent nuclear fuel from US power stations – and come up with nuclear security deals, including non-proliferation.

Non-proliferation “is the only field where Russia is ‘equal’ to the United States,” Tyshkevych said.
