Chinese military assistance to the Russians in Ukraine

Chinese military equipment with the forces fighting against Ukraine

Ramchan Kadyrov, the president of Chechnya and Putin's ally in the war in Ukraine, shows in a video new military armored vehicles made in China (Tiger).
Kadyrov's forces are fighting on the Ukrainian front alongside Russia.
This can be interpreted in the West as Chinese military assistance to the Russians in Ukraine, similar to the Iranian drones.
