The decision could make certain land disputes even worse.
On July 12, the tribunal hearing the case issued its ruling that can only be described as a huge win for the Philippines. Digesting all 507 pages of the award will take time, allowing only for preliminary judgments to be made. Below, I discuss several strategic implications.
The Scope of Lawful Maritime Claims in the South China Sea
In assessing the Philippine submissions, the tribunal greatly reduced the scope of maritime entitlements that states can claim in the South China Sea. First, the tribunal concluded that China lawfully, under the UN Convention on the Law of the Sea, claims historic rights to resources within the nine-dash line that appears on Chinese maps. Although China has not clarified the nine-dashed line or even explained officially what it means, the tribunal indicated that one potential explanation, as a claim to historic rights, was inconsistent with the convention. The tribunal reasoned that whatever historic rights or high-seas freedoms China enjoyed were “extinguished” when it acceded to the convention.
Second, the tribunal interpreted Article 121 of the convention, which outlines the “regime of islands.” In particular, the tribunal offered a four-part test for determining what constitutes an “island” and not a rock. This matters greatly because under the convention islands are entitled to a two-hundred-nautical-mile Exclusive Economic Zone, while a mere rock is entitled only to a twelve-nautical-mile territorial sea. The tribunal ruled that none of the naturally formed land features satisfied its four-part test and that no “islands” exist in the Spratlys from which China, or any other claimant state, can claim a two-hundred-nautical-mile EEZ.
