Beijing's commitment to rejecting decision in South China Sea not likely to be swayed by U.S. accession to UNCLOS

Second, the only thing that the United States would achieve by joining UNCLOS—at least from the perspective of modifying Chinese behavior—would be to deprive Beijing of its talking point that U.S. exhortations to claimant states to comply with UNCLOS amount to “hypocrisy.” Deprived of this talking point, there’s no reason to believe that Beijing would submit to the tribunal’s authority. Although U.S. ratification of UNCLOS would be a boost to the prestige of the convention, Beijing has evidently made a calculated judgment that defending its perceived sovereignty and the strategic value of physical control of large stretches of the South China Sea outweighs whatever reputational damage it suffers as a result of flouting the tribunal’s decision.
