The U.S. State Department has accused China of using the coronavirus pandemic as a cover "to assert unlawful maritime claims" in the region. That's after a Chinese coast guard vessel allegedly rammed and sunk a Vietnamese fishing boat last week near the disputed Paracel Islands. Beijing's no stranger to what U.S. officials claim is the "bullying" of its neighbors in the South China Sea — which Vietnam calls the East Sea.
What else has China been doing? Washington claims Beijing has also boosted its presence on two local military bases.
