Five navigational buoys have been installed by the Philippine Coast Guard in critical areas in the West Philippine Sea (WPS). The floating markers were placed on Patag (Flat) Island, Balagtas (Irving) Reef, Kota (Loaita) Island, Panata Island (Lankiam Cay), and Julian Felipe (Whitsun) Reef – all in the Kalayaan Island Group (Spratly Islands) – by the PCG’s Task Force Kaligtasan sa Karagatan (TF KsK) from May 10 to 12. The installation was part of the PCG's efforts to assert the country’s sovereignty and guide mariners in the tricky waters of the WPS.
