The diplomatic tug-of-war over the West Philippine Sea has reached a new flashpoint as the Philippine government’s initiative to officially name undersea features within the Kalayaan Island Group (KIG) triggered a swift and stern warning from Beijing.
In a move aimed at reinforcing its maritime jurisdiction and documenting its geographical heritage, the Philippines has moved to assign Filipino names to several seamounts and ridges within its 200-nautical mile Exclusive Economic Zone (EEZ). However, the Chinese Ministry of Foreign Affairs was quick to denounce the action, labeling it an “infringement” on its claimed territory and urging Manila to refrain from actions that could “complicate” the regional security situation.
For the Philippines, naming these features is a standard exercise of sovereign rights under the United Nations Convention on the Law of the Sea (UNCLOS). By replacing generic or foreign designations with local names, the government seeks to solidify its administrative hold over the area, which is rich in biodiversity and potential energy reserves.
“Naming is an act of ownership and administration,” a maritime law expert noted. The features, located in the waters off Palawan, are part of the broader Spratly Islands—an archipelago where several nations, including Vietnam, Malaysia, and Taiwan, have overlapping claims.
Beijing’s reaction was consistent with its long-standing “Nine-Dash Line” claim (now often referred to as the Ten-Dash Line), which asserts Chinese sovereignty over nearly the entire South China Sea. China maintains that any unilateral naming or surveying by the Philippines in these “disputed” waters is illegal and carries no international legal weight.
The warning from Beijing often precedes increased maritime presence, leading to concerns among Filipino fisherfolk and the Philippine Coast Guard (PCG). In recent months, encounters between Philippine resupply missions and Chinese maritime militia vessels have become increasingly frequent, and this latest diplomatic spat is expected to add another layer of tension to the next patrol cycle.
The Department of Foreign Affairs (DFA) has remained firm, asserting that the Kalayaan Island Group is an integral part of Philippine territory. The naming project is supported by various government agencies, including the National Mapping and Resource Information Authority (NAMRIA), which is tasked with updating the official maps of the Republic.
This move also aligns with the “Transparency Strategy” adopted by the current administration, which involves publicizing maritime incidents and assertively documenting Philippine activities in the West Philippine Sea to garner international support.
As the Philippines continues to map its maritime frontiers, the international community—particularly allies like the United States, Japan, and Australia—is watching closely. These nations have repeatedly called for a rules-based order in the region and have expressed support for the 2016 Arbitral Ruling, which invalidated China’s expansive claims.
The battle over names may seem symbolic, but in the world of geopolitics, it is a high-stakes game of cartography that defines the future of regional resources and national pride.
