Your analogy is flawed. China is Mexico in the analogy.
Chicoms are trying to keep Philippines from accessing their own territory.
You shill for Chicoms and assert it is Chicom territory.
Using Mexico as an analogue to China-
It would be as if Mexico claimed the entire Gulf of Mexico along the US coastline beyond the 12-mile limit, from Brownsville TX to Key West FL.
Any domestic or international shipping would require Mexican permission to enter the Houston ship channel, the ports of New Orleans, Mobile, Tampa, etc. And all offshore oil/gas in the Gulf would belong to Mexico.
