The Philippine Coast Guard (PCG) has deployed an aircraft to challenge the presence of a Chinese deep-sea research vessel spotted near the country’s northern coastline, escalating tensions in one of the Indo-Pacific’s most sensitive maritime zones.

In a statement, the PCG said the Chinese vessel Tan Suo Er Hao was detected about 19 nautical miles off the coast of Cagayan province in northern Luzon. The ship, which is capable of supporting submersible and deep-sea research operations, was found operating within the western portion of the Philippines’ Exclusive Economic Zone (EEZ).

During an aerial patrol, PCG pilots issued multiple radio challenges to the vessel, seeking confirmation on whether it was conducting marine scientific research without prior authorization from Manila. Under Philippine law and international maritime regulations, foreign vessels must obtain consent before carrying out research activities inside a coastal state’s EEZ. The Chinese ship did not respond to any of the radio communications, according to the coast guard.

The 87.25-metre-long research vessel reportedly departed from China’s Hainan province earlier this month before entering waters claimed by the Philippines. Coast guard monitoring later showed the ship moving eastward, approximately 55.8 nautical miles off the town of Santa Ana in Cagayan.

The PCG said the vessel was initially detected through Canada’s satellite-based Dark Vessel Detection system, which is used to identify maritime activity that may not be fully visible through standard tracking methods.

Cagayan is strategically significant as it hosts one of the military facilities accessible to United States forces under the Enhanced Defense Cooperation Agreement (EDCA), adding geopolitical sensitivity to the incident amid growing regional rivalries.

China’s embassy in Manila defended the ship’s movements, stating that the vessel was engaged in normal maritime manoeuvres. Beijing also reiterated its long-standing position that it does not recognize certain Philippine domestic maritime laws and asserted its right to navigate through the waters under international maritime rules.

The incident unfolded against a backdrop of rising regional tensions. On the same day, China conducted large-scale military exercises around Taiwan, firing rockets into surrounding waters and simulating blockades and strike operations as part of drills named “Justice Mission 2025.” The exercises followed the United States’ announcement of a record arms package for Taiwan.

Philippine Defense Secretary Gilberto Teodoro voiced deep concern over China’s recent military and coast guard activities in the region, warning that such actions undermine peace and stability not only across the Taiwan Strait but across the broader Indo-Pacific.

He said the expanding scale of coercive operations carries implications that go beyond cross-strait relations and poses wider challenges to regional security and international order.
