What is the bases and manifestations of our sovereignty over Kalayaan Group of island in the spratlys?

The bases of our sovereignty over the Kalayaan Group of Islands in the Spratlys primarily stem from historical claims, international law, particularly the United Nations Convention on the Law of the Sea (UNCLOS), and continuous governance and administration of the area. Manifestations of this sovereignty include the establishment of a military presence, civilian settlements, and the exercise of administrative functions, such as issuing permits for fishing and resource exploration. Additionally, diplomatic efforts and participation in multilateral discussions underscore the Philippines' commitment to asserting its rights over this territory.
