The Philippines is expanding its maritime security and regulatory partnerships through various regional and international channels. Initial efforts focused on exploring cooperation with Taiwan to protect critical undersea communication cables in the Bashi Channel, specifically to counter maritime “gray-zone” activities and safeguard intercontinental data flows.

Further developments include enhancing maritime standards and seafarer training through engagement with the European Commission. Additionally, the Philippines has increased its security interoperability through multilateral Maritime Cooperative Activities involving the United States, Japan, and the Armed Forces of the Philippines within the Philippine Exclusive Economic Zone. These exercises aim to improve maritime domain awareness, law enforcement, and search and rescue capabilities.
