President Ferdinand Marcos Jr. has issued Executive Order (EO) No. 111, mandating the adoption of a standardized set of Philippine names for 131 distinct maritime features within the Kalayaan Island Group (KIG). These features, encompassing islets, sandbars, atolls, reefs, shoals, and sand cays, are situated within the Kalayaan municipality of Palawan province, an area that forms a critical segment of what the Philippines refers to as the West Philippine Sea. The Presidential Communications Office announced that the directive aims to ensure the "efficient administration and governance" of these territories and to bolster the country's exercise of its sovereignty.
This executive order is a potent declaration of Manila's resolve, directly reinforcing its legal and historical claims in a strategically vital and resource-rich expanse of water that has become a flashpoint for regional tensions. By institutionalizing Philippine nomenclature across government and educational sectors, the Marcos administration seeks to solidify its national identity and territorial assertions against competing claims, most notably from Beijing, while underscoring its commitment to international law.
The decision to standardize these names was made upon the recommendation of the National Maritime Council (NMC), which emphasized the imperative of adopting indigenous names for these maritime features. According to the NMC, this standardization is essential for demonstrating Manila's inherent right to name features within its sovereign territory, sovereign rights, and jurisdiction, consistent with international law, particularly the United Nations Convention on the Law of the Sea (UNCLOS). The Department of Foreign Affairs further clarified that this act formalizes the use of these names across all government agencies, contributing to the broader implementation of Republic Act No. 12064, also known as the 2024 Philippine Maritime Zones Act.
Enacted just two years prior, the Philippine Maritime Zones Act legally defined the maritime zones on the western side of the Philippine archipelago. This foundational legislation explicitly identified the Luzon Sea, Bajo de Masinloc (Scarborough Shoal), and the maritime features of the Kalayaan Island Group as collectively constituting the West Philippine Sea. President Marcos's latest executive order serves as a direct extension and reinforcement of this domestic law, ensuring that the country's official nomenclature consistently reflects its legal and historical claims.
The implications of EO 111 extend beyond mere cartography. It explicitly mandates the National Mapping and Resource Information Authority (NAMRIA) to produce and publish updated charts and maps that incorporate these newly adopted names. This directive ensures that official navigational and geographical representations of Philippine territory are consistent with the government's assertive stance.
Furthermore, all national government agencies, including government-owned or -controlled corporations and government financial institutions, are now required to use these standardized Philippine names in all official communications, messages, and documents. This widespread institutionalization of nomenclature aims to project a unified national stance on the territorial issue, leaving no ambiguity in official discourse regarding the country's claims.
Perhaps even more far-reaching is the directive to the educational sector. The Department of Education, the Commission on Higher Education, the Technical Education and Skills Development Authority, and all state universities and colleges are instructed to integrate these standardized names into their educational and training institutions. This comprehensive initiative includes using them in research, publishing textbooks, and preparing instructional materials for students at all levels. This aims to embed the Philippine identity of these features within the national consciousness from an early age, ensuring future generations are thoroughly educated on the country’s territorial assertions and historical claims.
The move comes amidst a backdrop of escalating maritime incidents and persistent confrontations in the West Philippine Sea, particularly involving Philippine and Chinese vessels. China continues to lay expansive claims over nearly the entire South China Sea, often disregarding the 2016 international arbitral ruling that invalidated Beijing’s historical claims. Manila has increasingly adopted a more assertive stance under President Marcos Jr., characterized by greater transparency in reporting Chinese aggression and a fortified diplomatic push to rally international support for its maritime rights.
The adoption of local names is not without precedent in the Philippines' broader strategy to assert its sovereign rights. The nation previously demonstrated its commitment to naming its maritime territories under the administration of President Benigno Aquino III in 2012, when it officially designated the crucial waterway nearest its coast as the West Philippine Sea. This current executive order builds directly on that historical action, further solidifying the Philippines' resolve to delineate and assert its jurisdiction over the features within this designated area.
Senator Erwin Tulfo, who chairs the Senate Committee on Foreign Relations, publicly lauded President Marcos Jr.'s decisive action, characterizing it as an "important step in reinforcing our sovereign rights." Such endorsements from key legislative figures underscore the bipartisan support for measures aimed at safeguarding national interests in the West Philippine Sea. The government's messaging consistently emphasizes that these actions are part of broader efforts to strengthen governance mechanisms and reaffirm the Philippines' territorial claims in the strategically vital and resource-rich waters, where competing claims and tensions continue to pose significant challenges to regional stability.
This order sends a clear signal to both domestic and international audiences about the Philippines' unwavering commitment to its territorial integrity. By formally renaming these features, Manila reinforces its legal and historical narrative, transforming a symbolic act into a tangible instrument of policy and national identity, while projecting a unified front on the international stage.
The Philippines' consistent efforts to define and assert its maritime zones are rooted in the 1982 UNCLOS, which establishes a comprehensive legal framework for ocean activities. The 2016 arbitral ruling by the Permanent Court of Arbitration in The Hague definitively sided with the Philippines, invalidating China's sweeping "nine-dash line" claims over much of the South China Sea and affirming the Philippines' sovereign rights over its exclusive economic zone. Despite this international legal victory, Beijing has refused to acknowledge the ruling, continuing its expansive activities, including the construction of artificial islands, militarization of features, and regular harassment of Philippine vessels. This persistent defiance underscores the challenging environment in which Manila operates.
The Kalayaan Island Group and the broader West Philippine Sea hold immense strategic and economic significance. It encompasses vital international shipping lanes through which trillions of dollars in trade pass annually, making it critical for global commerce. Beyond its strategic corridors, the area is believed to harbor vast reserves of oil and natural gas, along with rich fishing grounds that are essential for the food security of littoral states. The overlapping claims by Vietnam, Malaysia, Brunei, Taiwan, and China, alongside the Philippines, create a complex geopolitical mosaic, where every assertion of sovereignty, such as this renaming initiative, carries significant weight.
As the West Philippine Sea remains a critical geopolitical flashpoint, marked by daily challenges to maritime security and stability, the Philippine government's move to codify the names of its KIG features serves as a quiet but firm declaration of ownership. This action shapes not only maps and official documents but also aims to embed a collective understanding of Philippine territory for decades to come, even as the broader tensions in the region show no signs of abatement.
