Sovereignty and International Recognition
Sovereignty and International Recognition
The Philippines' claim to Benham Rise was confirmed by the United Nations in 2012, granting the country sovereign rights over the area under the United Nations Convention on the Law of the Sea (UNCLOS). This recognition is crucial, as it establishes the Philippines' exclusive rights to explore and exploit the region's resources.
Key Aspects of Sovereignty
The Philippine government successfully filed a claim with the UN Commission on Limits of Continental Shelf in 2009, establishing its rights to the extended continental shelf in the region.
The area is classified as part of the Philippines' extended continental shelf, which extends 200 nautical miles from the baselines. The Philippines has exclusive rights to explore and exploit the region's resources, including fisheries, oil, and gas.
Additionally, the Philippine Rise was designated as a protected food supply exclusive zone in 2017, with specific areas declared as Strict Protection Zones for scientific research, banning mining and oil exploration.
Emphasis on Sovereignty
The Philippines' emphasis on sovereignty over Benham Rise is critical, particularly amidst concerns over foreign activities, such as those from China, which have raised questions about navigation rights and potential resource exploitation in the area.
