Philippines to rename disputed South China Sea islands to boost ‘sovereignty’

The Philippine government has taken a significant step to assert its territorial claims by announcing it will rename over 100 islands, reefs, and other features in the disputed South China Sea. President Ferdinand Marcos Jr. signed an executive order targeting features within the Spratly archipelago, a region that has been the site of repeated and tense confrontations between Philippine and Chinese coast guard and militia vessels. The presidential palace stated the renaming will "strengthen administration and governance, as well as sovereignty" in the area, which Manila officially refers to as the West Philippine Sea.

This strategic move follows a precedent set in 2012 under then-President Benigno Aquino III, who officially renamed the waters within the country's exclusive economic zone. The new order directs all government agencies and educational institutions to begin using the forthcoming Philippine names, effectively embedding the claim into official documentation and public discourse. The action directly challenges China's expansive "nine-dash line" claim, which was invalidated by an international tribunal in 2016—a ruling Beijing continues to reject.

The renaming initiative represents a diplomatic and symbolic escalation in the long-standing maritime dispute. It reinforces Manila's legal and administrative posture amid ongoing skirmishes at sea, such as those around Second Thomas Shoal. By formally cataloging and naming these features, the Philippines aims to solidify its historical and legal standing on the international stage, countering China's efforts to alter the status quo through island-building and patrols. The yet-to-be-released names will become the new standard for all official Philippine maps and communications.
