Communist China will accomplish that BEFORE they ever alienate Russia for zero worthwhile gain.
Communist Chinese action toward Russia primarily gives Russia more and better weapons, makes Russia stronger, reduces Russian costs, and reduces time necessary for adaption.
More likely, it will shorten the war, and increase costs for those supporting Ukraine and costs for Ukraine itself.
Communist China’s one certain purpose is to weaken, collapse and replace the United States as the world’s uni polar superpower,==
China is not communist at all. US is more of that than Chine this days.
Secondly the unipolar world showed its bad. No competition and a hegemony of one country is appalling. And after all China never takes place of US and possess a hegemony for herself.
So US will continue to be a pole in our world but not only one pole. So what China does now is good for everyone and the US population too.
Let be 2 poles in our world. Let be US and China but only US.
