Can't see the PLA (N) taking on the US Navy across the board - pointless and as they'd be massacred
China is more likely to go asymmetric
BUT they would come out fighting for Taiwan - that is an absolute certainty. They could concentrate their forces and the US would have the choice of a very hard fight , with very significant casualties , for a place they've always been in 2 minds about. As the Imperial German Navy as stated inpre WW1 -" we don't have to be big enough to beat the British. We only have to be big enough to do them so much damage that they are then significantly weakened in the face of other large navies".
