Ukraine's Foreign Ministry said on Tuesday it had summoned China's ambassador and told him of "serious concern" over Chinese involvement on Russia's side in the more than three-year-old war pitting Kyiv against Moscow.
The ministry said Deputy Foreign Minister Yevhen Perebyinis expressed "serious concerns about the facts of the participation of Chinese citizens in military action against Ukraine on the side of the aggressor-state and also the involvement of Chinese companies in the manufacture in Russia of military goods."
