Summary

The Philippine Coast Guard deployed its largest vessel, BRP Teresa Magbanua, and an aircraft to challenge the Chinese research ship Jia Hai Ke 7 operating off northern Batanes province between September 28 and October 2, 2026. The PCG conducted radio challenges and assertive maneuvering approximately 37-38 nautical miles northwest of Itbayat, Batanes, claiming the vessel was conducting unauthorized marine scientific research within the Philippine exclusive economic zone. The Philippines stated no consent was granted for such research and raised concerns about data collection near undersea cable corridors. China disputed the account, asserting the vessel was conducting normal operations in waters under Chinese jurisdiction and accused the Philippines of harassment. A China Coast Guard vessel arrived to escort the research ship. The two nations disagreed fundamentally over maritime jurisdiction in the area, with the Philippines citing UNCLOS requirements for coastal state consent to marine scientific research in the EEZ, while China asserted sovereign rights over the waters.
