U.S. assertion of rights and challenges to excessive claims lack credibility as long as we remain outside of treaty

As we look into the future, our status as a non-party will increasingly disadvantage the United States. Presently, the United States is forced to rely on customary international law as the basis for asserting our rights and freedoms in the maritime domain. In situations where coastal states assert maritime claims that exceed the rights afforded to them by the Convention, USPACOM challenges such claims through a variety of means including the U.S. Freedom of Navigation program, military-to-military communications, and diplomatic protests issued through the State Department. When challenging such excessive claims through military-to- military or diplomatic exchanges, the United States typically cites customary international law and the relevant provisions of the Convention. Unfortunately, because we are not a party to the Convention, our challenges are less credible than they would otherwise be. Other States are less persuaded to accept our demand that they comply with the rules set forth in the Convention, given that we have not joined the Convention ourselves.
