No, China does not want to obstruct the trade of its neighbors - yet, but as of now it wants to lean on them to, for instance, prevent migration of investment such as manufacturing plants, control capital flight, arrest it’s absconding citizens, prevent exploitation of resources in its neighbors economic zones (China claims ALL of the China sea areas and recognizes NONE of its neighbors economic zones). Give it a year or two and we will see demands for treaties of alliance, etc. China has hundreds of aircraft within range and capable of controlling these waters, or at least denying them to civilian use. The USN is a factor only if the US decides to oppose Chinese aggression. It hasn’t so far - see economic zones, fishing etc.
And frankly you are arguing in bad faith in denying all the above.
I am quite confident that China is not going to push matters to any point that would threaten the US or its allies in the region, especially given that it is in dire economic straits itself and the US is its biggest customer.
It would make absolutely no sense.
All these countries have conflicting overlapping claims.
Let’s see in a year or two if you or I am right.
