That stuff is also made in Vietnam, Malaysia, Indonesia, Phillipenes, Korea, India, etc etc etc.

If things get to that level of 'touchy' what makes you think shipping through that area wouldn't be interfered with? South Korea, Japan and arguably the Philippines are the main countries that wouldn't be going through areas that China regularly tries to claim or at least exercise authority over.

China does not have that kind of navy. Maybe it could build one, eventually. It will take decades... And it isn't just construction, it is the training and procedures and culture.

China hasn't fought a war in anyone's living memory. That is a hard place to fight nearly the whole world from.
