Official Map Release and Compliance
The National Mapping and Resource Information Authority (Namria) of the Philippines has released an updated official map that delineates the West Philippine Sea and establishes the country's maritime limits. This updated representation adheres to both domestic law and international standards, consistently using the designation "West Philippine Sea," in accordance with government policy adopted in 2012. The map is reflected across various official administrative, topographic, and thematic maps, as well as nautical charts utilized for navigation.
Context of the Map Release
The release of the updated map comes at a time of heightened tensions between Philippine and Chinese officials regarding the West Philippine Sea dispute. The map aims to clarify the boundaries of the Philippines' exclusive economic zone (EEZ), which is defined under international law to extend up to 200 nautical miles (370.4 kilometers) from the country's archipelagic baselines. Namria emphasized that the EEZ's boundaries are not represented by straight-line segments but rather as a continuous curved boundary, which cannot be accurately depicted by a simple list of coordinates.
Technical Basis and Legal Framework
Namria's updated map was created using precise geospatial data derived from the archipelagic baselines defined under Republic Act No. 9522, the archipelagic baselines law. The agency stated that its nautical charts comply with international hydrographic standards and are utilized by both Philippine and foreign vessels navigating within Philippine waters. These charts are also submitted to technical bodies, including the International Hydrographic Organization, ensuring their reliability and accuracy.
Support for National Sovereignty
The updated map and accompanying charts are part of Namria's mandate to produce accurate geospatial information, which is essential for maritime safety, environmental management, disaster preparedness, and the documentation of national territory. Namria has reiterated its commitment to uphold national sovereignty and promote sound resource management through these efforts.
Criticism and Legal Clarifications
Amid the discussions surrounding the map, Senator Rodante Marcoleta raised concerns during a plenary debate regarding the lack of specific computations or coordinates for the West Philippine Sea. This assertion was countered by retired Supreme Court Senior Associate Justice Antonio Carpio, who clarified that the United Nations Convention on the Law of the Sea does not mandate coastal states to announce specific coordinates for their EEZs. Namria echoed Carpio's explanation, reinforcing the legal basis for the representation of the EEZ.
Conclusion
The release of the updated map by Namria is a significant step in reinforcing the Philippines' maritime claims and sovereignty in the West Philippine Sea. As tensions continue to simmer in the region, the agency's commitment to providing accurate geospatial information remains crucial for national interests and international navigation standards.
