In May, the Philippines and China took turns installing buoys in the disputed Spratly Islands. The deployment of buoys and other sovereignty markers in the South China Sea has a long history. But amid a flurry of new activity by the Philippines, including publicized patrols and surveillance missions, it is noteworthy that the buoy deployment triggered an almost immediate reaction from China, which installed its own. And with the Philippines planning to install more buoys by the end of 2023, this trend will remain a point of contention between Manila and Beijing for the foreseeable future.

On May 15, the Philippine Coast Guard installed 30-foot navigational buoys at five features in the Spratly Islands: Philippine-occupied Flat Island, Loaita Island, and Loaita Cay, and unoccupied Irving Reef and Whitsun Reef. The buoys are of the same type as five installed in May of 2022 at four Philippine-occupied features: Nanshan Island, West York Island, Northeast Cay, and Thitu Island.

On July 12 , 2016, an arbitral tribunal issued a long-awaited ruling in Manila’s case against Beijing’s claims in the South China Sea. How did the judges rule and how does the area of the South China Sea they found to be legally disputed compare to China’s infamous nine-dash line claim?

The tribunal invalidated Beijing’s claims to ill-defined historic rights throughout the nine-dash line, found that Scarborough Shoal is a rock entitled only to a 12-nautical-mile territorial sea, and surprised many observers by ruling on the legal status of every feature in the Spratly Islands raised by the Philippines. It found that none of the Spratlys, including the largest natural features—Itu Aba, Thitu Island, Spratly Island, Northeast Cay, and Southwest Cay—are legally islands because they cannot sustain a stable human community or independent economic life. As such, they are entitled only to territorial seas, not EEZs or continental shelves. Of the seven Spratlys occupied by China, the court ruled that Johnson Reef, Cuarteron Reef, Fiery Cross Reef, and Gaven Reef are rocks, while Hughes Reef and Mischief Reef are below water at high-tide and therefore generate no maritime entitlements of their own. It also ruled that Kennan Reef is a low-tide elevation, while Second Thomas Shoal and Reed Bank are submerged and belong to the Philippine continental shelf. Taken together, these decisions effectively invalidate any Chinese claim within the nine-dash line to more than the disputed islets themselves and the territorial seas they generate.
