President Ferdinand Marcos Jr. has mandated the use of Filipino names for 131 maritime features in the West Philippine Sea, a cartographic assertion of sovereignty that directly challenges Beijing's territorial claims in the disputed waters.
The executive order, signed Monday and reported by Rappler, requires all government agencies, educational institutions, and official maps to use the newly designated Filipino names for reefs, shoals, and underwater features within Manila's exclusive economic zone.
The move transforms geography into geopolitics. Features previously known by international designations now carry names like Kalayaan (Freedom) and Pagasa (Hope), anchoring Filipino identity to waters that China claims under its sweeping nine-dash line.
Naming is not symbolic - it's strategic. Under international law, consistent use of indigenous toponyms strengthens sovereignty claims. Vietnam has pursued a similar strategy in the Paracel Islands, and Indonesia renamed the northern reaches of the Natuna Sea in 2017, explicitly rejecting Chinese maps that showed overlapping claims.
The executive order comes one day after former Justice Antonio Carpio warned against accepting China's joint energy development terms, revealing a coordinated Manila strategy: assert sovereignty through law, language, and cartography while resisting agreements that would implicitly concede territorial rights.
The 131 features include Reed Bank (Recto Bank in Filipino), a gas-rich area where Chinese vessels have repeatedly blocked Filipino boats, and Scarborough Shoal (Bajo de Masinloc), effectively controlled by China since a 2012 standoff but never formally ceded by Manila.
Education Secretary Sonny Angara said new textbooks will incorporate the updated maps by the next school year. The Department of Foreign Affairs will distribute the standardized names to ASEAN partners and submit them to the United Nations Geographic Names Database.
Beijing has not yet responded, but past reactions to similar moves suggest a strong diplomatic protest is likely. China maintains that its historical claims predate modern international law, a position the 2016 Hague tribunal rejected but which Beijing refuses to recognize.
Ten countries, 700 million people, one region - and in the West Philippine Sea, the battle is fought not just with coast guard vessels and oil rigs, but with the names printed on maps and taught in classrooms, anchoring claims that will outlast any government.
