Ukraine says more than 150 Chinese mercenaries are fighting for Russia in Ukraine

KYIV, Ukraine — Ukraine on Wednesday expanded on its claim that significant numbers of Chinese nationals are fighting for Russia’s invading army, saying it had gathered detailed intelligence on more than 150 mercenaries Moscow allegedly recruited through social media. In China, officials called the allegations “totally unfounded.”

The Ukrainian accusation and Chinese denial come as the U.S. strives to secure a ceasefire in the more than three-year war.

President Volodymyr Zelenskyy announced Tuesday that the Ukrainian military had captured two Chinese men fighting alongside the Russian army on Ukrainian soil. It was the first time Ukraine had made such a claim about Chinese fighters in the war.

On Wednesday, Zelenskyy said he was willing to exchange the two prisoners of war for Ukrainian soldiers held captive in Russia. Without providing evidence, Zelenskyy said officials in Beijing were aware of Russia’s campaign to recruit Chinese mercenaries. He stopped short of saying the Chinese government authorized the mercenaries’ involvement in Ukraine.

Zelenskyy said Ukraine has the last names and passport data for 155 Chinese citizens fighting for the Russian army and that “we believe that there are many more of them.” He shared with journalists documents listing names, passport numbers and personal details of the alleged Chinese recruits, including when they arrived in Russia for military training and departed for service; the AP has not independently verified the documents.

China has provided strong diplomatic support for Russia since it launched its full-scale invasion of Ukraine in February 2022. It has also sold Russia machinery and microelectronics that it can use to make weapons, Western officials say, in addition to providing an economic lifeline through the trade in energy and consumer goods.

China is not believed to have knowingly provided Russia with troops, weapons or military expertise.

U.S. officials have accused Iran of providing Russia with drones, while American and South Korean officials say North Korea has sent thousands of troops and ammunition to help Russia on the battlefield.

With the U.S. and Europe having provided substantial military support and diplomatic heft for Ukraine, the war has to some degree become a contest between power blocs.

Tensions between the U.S. and China have deepened in recent years. Disputes have centered on geopolitical influence, technology and trade -- and recently escalating import tariffs between the countries have roiled global financial markets. Zelenskyy said U.S. officials expressed “surprise” when informed of the presence of Chinese mercenaries in Ukraine.

U.S. President Donald Trump is trying to follow through on a campaign promise last year to swiftly end the war in Ukraine.

U.S. State Department spokesperson Tammy Bruce said at a briefing in Washington on Tuesday that reports of Chinese citizens fighting on behalf of Russia were “disturbing.”

“China is a major enabler of Russia in the war in Ukraine,” Bruce said. China provides nearly 80% of the dual-use items Russia needs to sustain the war, she claimed.

But Keith Kellogg, Trump’s special envoy to Ukraine and Russia, said he is “not convinced yet” the Chinese personnel identified as fighting on behalf of Russia against Ukraine are more than mercenaries or volunteers.

“There’s an axiom in the military, the first report is always wrong,” Kellogg said during a Wednesday appearance at Georgetown University. “And this is one of those let’s sit back and see how this plays out, because it could be volunteers.”

Kellogg noted that Ukraine also has volunteers from other countries, including the United States, fighting on its behalf. He added that the early reports of Chinese personnel are not on par with North Korea’s deployment of thousands of troops to the frontlines.

The European Union’s foreign policy chief, Kaja Kallas, also called Beijing “the key enabler of Russia’s war.”

Dual-use goods are entering Russia via China, she said in Brussels, adding “it’s clear that if China would want to really stop the support then it would have an impact.”

China has surged sales to Russia of machine tools, microelectronics and other technology that Moscow in turn is using to produce missiles, tanks, aircraft and other weaponry for the war, according to a U.S. assessment last year.

The Kremlin has effectively rejected a U.S. proposal for an immediate and full 30-day halt in the fighting in Ukraine. The Kyiv government has consented to it. Both sides are believed to be readying spring-summer military campaigns.

Chinese Foreign Ministry spokesperson Lin Jian said in Beijing that China has played a “constructive role in politically resolving the Ukraine crisis.”

Lin told a daily news briefing Wednesday that “the Chinese government always asks Chinese citizens to stay away from conflict zones, avoid getting involved in any form of armed conflict, and especially refrain from participating in any party’s military operations.”

His comments appeared to indicate that the captured Chinese had joined Russia’s ranks on their own initiative. Both Russia and Ukraine allow foreign soldiers to enlist.

China has previously put forward a vague peace plan that was swiftly dismissed by most observers.

In the meantime, both countries have kept fighting a war of attrition along the roughly 1,000-kilometer (620-mile) front line and targeted each other with long-range strikes.

The city of Kramatorsk in Ukraine’s eastern Donetsk endured a “massive drone attack” overnight, regional head Vadym Filashkin said, injuring an 11-year-old girl, her mother and her grandmother.

Ukraine’s air force said Russia launched 55 Shahed and decoy drones at the country overnight.

The Russian Defense Ministry said that air defenses downed 158 Ukrainian drones over 11 Russian regions overnight but reported no casualties or damage.

Several Russian regions temporarily suspended flights at their airports because of the attack, however, and some Ukrainian drones reached Russia’s Orenburg region in the southern Urals located nearly 1,200 kilometers (745 miles) east of the Ukrainian border, the Defense Ministry said.
