I suspect there will be much political dislocation in China when Xi steps down, or much worse (for the CCP), if he were to die suddenly of natural causes.
The PLAN surface ship build up seems directed at local navies. For the US, the effort seems more focused on missiles to engage US surface ships, particularly CVNs, as a deterrent to them getting involved in regional wars. They have a number of exotic high speed projects going in this direction, and at least a few types of super sonic missiles in service.
They don't see to have a particular good answer to USN nuke boats yet outside perhaps flooding the first island chain with ships an accepted the casualties associated with that.
I don't think they are planning on takling the US face to face, mainly because they don't need to, but they are certainly worried about their SLOC to their clients which can be cut by their enemies with ease, which explains why they invest so much on escorts and carriers yet they neglect SSNs and ASW. ASBMs can provide the anti-carrier capability required vs the US, but the US can cut the Chinese SLOC and not be near the Pacific Ocean, so it's an interesting capability but irrelevant.
I don't think so as well, at least not anywhere outside of their force multiplier zones, which is disappointing.
