Tensions in the South China Sea continue to escalate as the Philippines bolsters its defense partnerships with key allies amid increasing maritime disputes with China. In early February 2025, a series of international naval drills and joint military operations signaled a strong response to Beijing’s assertiveness in the contested waters.

Naval Drills and Regional Response

The United States, Australia, Japan, and the Philippines conducted joint naval exercises within the Philippines’ Exclusive Economic Zone (EEZ) in early February. These drills, aimed at enhancing interoperability and security cooperation, drew sharp criticism from China, which accused the Philippines of aligning with foreign forces to destabilize the region.

Adding to this strategic shift, Canada and the Philippines are finalizing a defense pact that will enable more extensive joint military exercises and intelligence sharing. Canada has also committed to providing satellite technology to assist Manila in monitoring illegal maritime incursions.

Joint Patrols Over Disputed Waters

In a significant show of force, U.S. and Philippine fighter aircraft carried out joint patrols over the Scarborough Shoal, a hotly contested area claimed by both nations. This move underscores the growing military coordination between Washington and Manila in response to China’s increasing presence in the region.

Political Shifts in the Philippines

Amid these security developments, domestic politics in the Philippines have also undergone major shifts. Vice President Sara Duterte was recently impeached by the House of Representatives on multiple charges, including alleged corruption and failure to oppose China’s aggressive actions in the South China Sea. The Senate is expected to hold an impeachment trial later this year, potentially reshaping the country’s political landscape at a critical time.

The Bigger Picture

The latest developments indicate a clear shift in the Philippines’ defense posture, with stronger ties to Western allies countering China’s growing influence in the South China Sea. As joint military actions intensify and new defense agreements take shape, the dispute remains a focal point of regional and global geopolitics.
