Adm. Samuel Locklear says rival claimants might need to seek compromises to resolve the feud over potentially oil-rich areas of the sea.
Locklear did not mention any country by name, but China's increasingly aggressive claims to disputed islands have triggered worries about confrontations with others including the Philippines, Vietnam, Malaysia and Brunei.
Locklear told reporters during a visit to Malaysia today that the US "will oppose the change of status quo by force by anyone."
