China doesn’t have the Navy to setup a blockade

Do you have sources that backs up that claim? Just because they didn’t do so in a sabre rattling exercise doesn’t mean they can’t. Afaik their navy is actually quite capable, and actually it’s the largest in the world by number of vessels.

As of 2024, the PLAN(PLA Navy) is the second-largest navy in the world by total displacement tonnage[18] — at 2 million tons in 2021, behind only the United States Navy (USN)[19] — and the largest navy globally by number of active sea-going ships (excluding coastal missile boats, gunboats and minesweepers)[20][21] with over 370 surface ships and submarines in service,[22] compared to approximately 292 ships and submarines in the USN.[23]
