Short of the US getting pulled into an extended war elsewhere it cannot extricate itself from until China is too much of a peer power to even risk a fight it is going to fight China as part of the larger push of decoupling, containment, humiliation. Almost certainly over Taiwan, they don’t need to win per se, just inflict damage, bleed China and rally the western world and any hangers-on (India probably) to their side for sanctions and cutting economic and cultural ties as they do to China and Chinese people and culture what they did to Russia with the Ukraine war but much worse.

China just needs to be prepared and accept this. They need to prepare for war, they need to prepare for the possibility of cold war, of being completely cut off from the west and make plans for how they’ll restructure their economy to survive that if it comes. They need to build out their nuclear deterrent as much as possible to deter the US from a decapitating strike attempt and they need to prepare for a much more hostile and western empowered India on their border.
