Summary

The Philippine Coast Guard deployed its largest vessel, the BRP Teresa Magbanua, and an aircraft to confront the Chinese research ship Jia Hai Ke 7 operating near Batanes province in the Philippines' exclusive economic zone starting September 28. The Philippines alleged the vessel was conducting unauthorized marine scientific research and claims it manipulated its Automatic Identification System. A China Coast Guard cutter appeared to escort the Chinese vessel. The Philippine Department of Foreign Affairs stated it had not authorized any Chinese research activities in the area and characterized the Coast Guard's actions as standard enforcement. China disputed this account, claiming the research ship was conducting normal operations in waters under Chinese jurisdiction and characterizing Philippine actions as harassment. The two nations disagreed over maritime jurisdiction in the area, with China citing its sovereign rights and the Philippines asserting its exclusive economic zone rights under international law.
