The Philippines has asked a United Nations body to formally recognise the extent of its undersea continental seabed in the South China Sea in a move that rejects China’s vast territorial claims to the region.
Manila submitted information to the UN Commission on the Limits of the Continental Shelf on the extent of its undersea shelf in the South China Sea, off western Palawan province.
China did not immediately comment but it will likely contest the Philippine move.
The undersea region where the Philippines seeks to formally establish its sovereign rights covers the Spratlys, a chain of islands, islets, reefs and atolls that has been fiercely contested over the years by China, the Philippines, Vietnam, Malaysia, Brunei and Taiwan.
Indonesia has also confronted the Chinese coast guard and fishing fleets in the gas-rich Natuna Sea on the fringes of the South China Sea.
Philippine Foreign Assistant Secretary Marshall Louis Alferez said: “Incidents in the waters tend to overshadow the importance of what lies beneath.
“The seabed and the subsoil extending from our archipelago up to the maximum extent allowed by UNCLOS hold significant potential resources that will benefit our nation and our people for generations to come.
“Today, we secure our future by making a manifestation of our exclusive right to explore and exploit natural resources in our extended continental shelf entitlement.”
Under the 1982 UN convention, a coastal state could have exclusive rights to exploit resources in its continental shelf, including the right to authorize and regulate any kind of drilling.
Manila’s undersea continental shelf could potentially overlap with those of other coastal states in the South China Sea, including that of Vietnam.
Philippine officials expressed readiness to hold talks to resolve such issues based on UNCLOS.
Manila permanent representative to the UN Antonio Lagdameo said the move “can reinvigorate efforts of states to demonstrate their readiness to pursue UNCLOS processes in the determination of maritime entitlements and promote a rules-based international order.”
Hostilities and tensions in the disputed waters have alarmingly escalated particularly between China and the Philippines over two disputed shoals since last year.
Chinese coast guard ships and suspected militia vessels have used powerful water cannons and dangerous blocking manoeuvres against Philippine coast guard patrol ships and navy boats that have injured Filipino Navy personnel, damaged their supply boats and strained diplomatic relations between the two countries.
After a tense standoff between Philippine and Chinese ships near a shoal in 2012, the Philippines brought its disputes with China the following year to international arbitration.
The arbitration panel invalidated China’s claim to virtually the entire South China Sea in a 2016 ruling but Beijing refused to participate in the arbitration, rejected the decision and continues to defy it.
