I believe, that China has no territorial claims on Chinas biggest economical partner US, but China has historical claims on territory of Russia. In a long game, China is waiting for Russia to become weak(just like Russia attacked Ukraine when it was weak), to claim(without fight) what is rightfully Chinese and what was stolen from them. So far, Chinese are getting all the resources from Russia and they will continue getting them even more in case of conflict. If Russia goes to war, it weakens itself - all according to Sun-Tzu teachings and in any case China is winner - it takes time, but the way is more important than short goals. Look on a globe and think of China as expansionists - the only best territorial expansion route to them is into Russia and Kazakhstan. It is a dream come true scenarion, that Russia is trying to be ally - or perhaps they realise, that this is their option.

Why would China be involved in this at all? This war disrupts Chinese non-military takeover of Silk Road territories, where they are dominant economical force already.

The only losers in this play are Russians, where only "brightest" of them think of such crazy scenario, that you are proposing. People in a way do not differ from lemmings - even millions of them can be wrong on their way down from cliff. But, while they are running amok, they have a goal - for that moment.
