China using U.S. non-party status to UNCLOS to bludgeon it for hypocrisy when U.S. challenges China's excessive claims

As a signatory to UNCLOS, the PRC occasionally implies that its interpretations should trump those of the United States, which has yet to ratify the convention that Washing- ton nevertheless employs as a bludgeon against Beijing’s claims that UNCLOS permits limitations by coastal states on foreign military activities in the EEZ. The message is that even though the United States asserts its compliance with UNCLOS, because it has not undertaken to be formally bound by the convention it has no standing to impose its self- regarding interpretations of the regime on those states that have ratified it.

For instance, Zhang Haiwen cites passages from an essay by Scott Borgerson to make the point that there is a “strong political force which is scornful of the Convention in the United States. They like to take advantage of the Convention but do not respect it.”¹¹ Zhang writes, “It is unfair . . . that the United States, which has yet to ratify the Convention, is raising an argument on the interpretation of the Convention.”¹² Reacting to what she views as Washington’s selective compliance with UNCLOS, Zhang highlights the following from Borgerson’s piece: “Opponents of the convention [UNCLOS] argue that there is no need to join the treaty [UNCLOS] because, with the world’s hegemonic navy, the United States can treat the parts of the convention it likes as customary international law, following the convention’s guidelines when it suits American interests and pursuing a unilateral course of action when it does not.”¹³

In these sentiments Zhang is not alone. Chinese observers have framed the dispute about UNCLOS as illustrative of U.S. hegemonic tendencies. “America’s failure to cooperate with the international community on UNCLOS is not an isolated phenomenon,” writes one commentator, “but is one element in its strategy to dominate the world and monopolize the oceans.”¹⁴
