China could never support a pro-Western Ukraine in the first place. The same logic applies to Iran, North Korea, etc.
Although China cannot directly express support because of foreign trade, things like the Communist Youth League playing "Katyusha" on the day Russia launched the invasion, and the information direction on social media, have already made their position very clear.

Weak Russia is more beneficial for China to buy commodities for cheap and then sell Chinese products back.
> China could never support a pro-Western Ukraine in the first place.
So nope - China dont care. They are trading with both Russia and Ukraine.
The CCP government has absolute control over domestic public opinion. The pro-Russia direction on Chinese social media is very clear, although as the war became unfavorable for Putin, voices supporting Ukraine have been allowed a little more in recent years.
What the US supports is what China opposes. From Iran to Venezuela, from Gaza to Ukraine, except for a very small amount of "human consensus", it is always and will be like this.
Of course China does not support Ukraine politically, but that's a different story.
