System Under Strain

Seabed mining became more active as companies invested in technologies to harvest valuable minerals. Momentum toward commercial mining would test directly the idea of international control of ocean space. The industry’s prospects also revived attention to whether the United States might join the Convention, and the Obama administration pushed to secure ratification. That effort failed, mostly because of conservative concerns about the internationalization of the seabed. Washington’s continued refusal to join the Convention created a complicated situation in which the leading maritime power claimed to defend maritime rules but was outside the Convention. From inside the Convention, China and Russia both challenged maritime rules. Both countries rejected international rulings critical of their maritime behavior. Despite an international ruling, China continued its efforts to secure special rights in the South China Sea, and the United States responded by increasing its naval activities in the area and conducting more freedom of navigation operations.
