THE Philippine Coast Guard (PCG) successfully expelled a Chinese research vessel, the Tan Suo 3, from the country’s exclusive economic zone (EEZ) on May 5, 2025.
The PCG deployed the BRP Teresa Magbanua and an aircraft to intercept the vessel, which had been conducting unauthorized marine scientific research approximately 92 nautical miles off the coast of Burgos, Ilocos Norte, since May 1.
Commodore Jay Tarriela, PCG spokesperson for the West Philippine Sea, confirmed the successful operation in a press briefing on Tuesday. He stated that the combined efforts of the BRP Teresa Magbanua and the PCG aircraft effectively prevented the Tan Suo 3 from continuing its illegal activities.
As of Tuesday, the Chinese vessel was reported to be 250 nautical miles off the coast of Burgos, well outside Philippine waters.
The operation also involved the observation of a manned deep-sea submersible, the Shenhai Yongshi (Deep-Sea Warrior), which was seen approaching the Tan Suo 3 before being retrieved by its crew. Additionally, the PCG reported that the Tan Suo 3’s crew recovered a yellow piece of equipment believed to be related to their research activities.
Commodore Tarriela emphasized that the actions of the CRV Tan Suo 3 constitute a clear violation of Philippine sovereignty and international law. The unauthorized marine scientific research undertaken by the Chinese vessel, lacking the necessary legal permits, underscores the ongoing tensions in the region. The PCG’s decisive action serves as a strong statement of the Philippines’ commitment to protecting its maritime territory.
