China will invade or blockade Taiwan soon.
If China tries that, they risk interruption of their supply chains, imports and exports. China won’t get the oil they need.
In the first place, other countries will look for safe places to do business and avoid the war zone along the Chinese coast.
US navy would be there to ensure safety of supply lines to Japan, South Korea and SE Asia. US could intercept Ships going to and from China in a loose blockade.
It’s good that Trump forced this issue to a head while US still is in a position to stop Chinese hegemony. China is the preferred globalist power. All they do is lie, cheat and steal. Their word, their agreements are worthless.
According to Grok, China gets 93% of oil over sea and the rest via pipelines over land. A blockade would certainly slow them down..
