U.S. ability to advocate for joint development solution to South China Sea dispute hampered by its non-party status to UNCLOS

Open economic access to the South China Sea maritime commons is a second U.S. interest, but one which may diverge from freedom of navigation. Access to the resources of the high seas is an important enough U.S. interest to stall the ratification of UNCLOS for nearly 20 years. The United States remains outside the treaty, however, and holds less influence over how maritime law is interpreted and evolves, and thus is at a disadvantage to shape events like whether the South China Sea becomes a wholly divided and claimed sea. Such arrangements as a Joint Development Zone or a Joint Management Zone could stabilize the area and provide stability and economic development for its participants. To support any of the joint development solutions, the United States would have to place its security interests over potential economic ones.
