Japan-Philippines EEZ talks trigger Chinese patrols near Taiwan

Japan and the Philippines, despite sharing no land borders, have initiated formal negotiations to delimit the maritime boundary of their exclusive economic zones (EEZs) and continental shelves. Under the United Nations Convention on the Law of the Sea (UNCLOS), both coastal nations are entitled to claim EEZs extending 200 nautical miles from their shores. The talks, announced recently, aim to prevent overlapping claims and clarify resource rights in the waters between them. However, the region east of Taiwan—where their EEZs potentially converge—has been a sensitive area, with Beijing historically asserting its own maritime rights there.

China reacted swiftly, deploying its coastguard for enforcement patrols in the disputed waters on Monday. Beijing claims the patrols are to maintain its own EEZ and continental shelf rights under domestic and international law. The Taiwanese coastguard reported shadowing two Chinese vessels about 51–52 nautical miles southeast of Orchid Island (off Taiwan's southeastern coast). This move intensifies the ongoing geopolitical tensions, as China views Taiwan as part of its territory and opposes any external delimitation that could affect its claims. The boundary talks between Tokyo and Manila, combined with China's naval response, create a new flashpoint in the western Pacific, raising concerns over regional stability and freedom of navigation.
