This policy brief examines the crucial role of the Philippine Coast Guard (PCG) in safeguarding the West Philippine Sea (WPS) amid escalating geopolitical tensions. It outlines the PCG's history, legal mandates (Maritime Law Enforcement, Safety and Security, and Environmental Protection), and its evolution into an armed and uniformed service critical for national security. The brief highlights the PCG's non-military, law enforcement nature as advantageous for de-escalation in the contested WPS, allowing it to assert Philippine sovereignty without directly engaging in military conflict. It discusses the challenges the PCG faces, including limited resources and threats from foreign forces, and proposes policy recommendations to enhance its capabilities through increased funding, modernization, and international cooperation. The brief concludes that a strong, well-supported PCG is essential for effective maritime domain awareness, enforcement of national laws, and the protection of Philippine interests in the WPS.
