I don't feel like China operates under the same geopolitical philosophy as Russia, they have other ambitions that I think are better served by avoiding wars. But who knows given the way things are going.
It's clear if you pay attention, that China's putting inordinate efforts into other places. Africa is one example. (Probably the principal example.) So they clearly have ambitions that lay outside of Asia.
No one fakes moves like that at that scale. They're serious about what they're doing.
