Japan, Philippines Launch EEZ Talks Amid China's Military Expansion

Japan and the Philippines have officially begun negotiations to establish maritime boundaries in their overlapping exclusive economic zones (EEZs) and continental shelves. This significant step, announced following a summit between Japanese Prime Minister Fumio Kishida and Philippine President Ferdinand Marcos Jr., is viewed as a strategic maneuver to counter China's increasing military assertiveness in the Indo-Pacific.

Officials in Taiwan have assured that the ongoing talks between Tokyo and Manila will not infringe upon Taiwan's sovereign rights under international law. The Ministry of Foreign Affairs stated that it is closely monitoring the developments and maintaining communication with both Japan and the Philippines. They emphasized that any agreement reached will not impact Taiwan's existing maritime rights or its fisheries and law enforcement agreements with Japan and the Philippines.

The maritime boundary negotiations are primarily addressing overlapping claims between Japan and the Philippines, rather than expanding existing assertions. Japanese Chief Cabinet Secretary Yoshimasa Hayashi has explicitly stated that the bilateral agreement will have no binding effect on third countries. This clarification comes amid broader strategic cooperation, including the elevation of Japan-Philippines relations to a "comprehensive strategic partnership," which reiterates the importance of peace and stability in the Taiwan Strait.

The Japan-Philippines agreement has no binding effect on third countries.

The enhanced cooperation between Japan and the Philippines is part of a wider effort to bolster security within the first island chain and maintain maritime order. This aligns with Japan's updated "Free and Open Indo-Pacific" strategy and its strengthening security ties with like-minded nations such as the United States, Australia, and India. The initiative aims to counter China's "new normal" of military and maritime law enforcement activities, which have extended pressure across the first island chain, from the Yaeyama Islands to the Batanes Islands.

Taiwanese officials also criticized certain domestic opposition parties and media outlets for linking the Japan-Philippines EEZ talks to Taiwan's maritime interests, accusing the government of being slow to react and "losing sovereignty." These arguments, officials noted, closely mirror narratives promoted by Chinese state media. They warned that such discourse plays into China's strategy of dividing Taiwanese society and weakening democratic alliances in the region, urging a focus on the shared strategic context of countering China's expansionism.

Taiwan's security is inseparable from Japan's security, and the security of the Philippines is also inseparable from Japan's security.
