Q&A with Justice Antonio Carpio | UNLCOS and Maritime Rights in the West Philippine Sea

In relation to ongoing developments in the West Philippine Sea, legal questions continue to arise on how international maritime law applies—making it even more crucial to clearly explain the Philippines’ maritime rights and responsibilities under the United Nations Convention on the Law of the Sea (UNCLOS).

Recent discussions have touched on the existence of maritime zones, the role of arbitration, and jurisdiction in areas including Bajo de Masinloc (Scarborough Shoal), Ayungin Shoal (Second Thomas Shoal), and Escoda Shoal (Sabina Shoal). These issues can be complex and are often debated, which is why public understanding should be anchored on established legal frameworks and credible, official sources.

The Philippines’ maritime entitlements are based on UNCLOS, which defines the territorial sea, exclusive economic zone (EEZ), and other maritime regimes. These entitlements have also been examined in the 2016 Arbitral Award, which addressed key legal issues related to claims in the South China Sea.

To support informed public discussion, IMOA shares a Q&A featuring Justice Antonio Carpio, discussing relevant provisions of international law and clarifying how these frameworks relate to the Philippines’ maritime rights—particularly in managing marine resources, protecting fishermen, and exercising lawful jurisdiction in its waters.
