“There are 155 Chinese citizens who are fighting against Ukrainians on the territory of Ukraine,” President Volodymyr Zelensky confirmed this information to journalists on April 9.
“We are collecting information, we believe that there are many more.”
“For these 155 there is passport data, where they are from, their Chinese documents, age, etc,” Zelensky added.
According to Zelensky, Chinese soldiers had been serving with Russia’s 70th Separate Guards Motor Rifle Brigade, the 255th Rifle Division, and others.
A day before, President Volodymyr Zelensky announced the capture of two Chinese citizens fighting for Russia in eastern Donetsk Oblast. The group of six Chinese nationals clashed with Ukrainian forces, and two are now being held by the Security Service of Ukraine (SBU), he said.
The documents, obtained by the Kyiv Independent, list the names, personal data, place of service and position in the Russian army of other Chinese nationals.

One of the captured soldiers claimed he paid 300,000 rubles (roughly $3,000) to a middleman in China to join the Russian military in exchange for the promise of citizenship, Ukraine’s Luhansk military unit press service told Ukrainian Pravda earlier in the day.
“Beijing knows about this. Russians distribute advertising videos about recruitment through Chinese social networks,” Zelensky said.

In addition to comments by others in this thread I may draw your attention to the quote:
How is is possible that Russians “distribute advertising videos about recruitment through Chinese social networks” without the Chinese party-state knowing this? - The answer is, it isn’t. Everything that is only slightly critical of the government or inadvertently referencing to historical issues like the Tiananmen Square massacre is being censored on Chinese social media immediately. But Russia can run advertisements offering money and citizenship without Chinese censors catching on? And despite, according to Chinese officials, “Chinese citizens are prohibited from participating in foreign armed conflicts”?
(The answers to these two questions can only be, "No, because it is not very credible that this goes unnoticed by the Chinese censorship machine. ")
