A Chinese research vessel has been closely monitored by the Philippine Coast Guard (PCG) while sailing in different features of the West Philippine Sea (WPS), a coast guard spokesperson disclosed.

“Ke Xue San Hao,” a multi-purpose oceanographic research vessel, exhibited “irregular” Automatic Identification System (AIS) transmissions while navigating the northern part of Escoda (Sabina) Shoal at 4 p.m. Saturday, August 3, according to PCG spokesperson for WPS Commo. Jay Tarriela.

“Additionally, the BRP Teresa Magbanua (MRRV-9701) has been physically tracking the Chinese research vessel since it passed her dead astern approximately 5.5 nautical miles,” Tarriela said.

According to Tarriela, the Ke Xue San Hao is designed by the Marine Design and Research Institute of China.

It is equipped with advanced technology that enables comprehensive marine environment observation, detection, sampling, and analysis, the coast guard spokesman added.

Based on the PCG’s monitoring using the dark vessel detection program, the Chinese research vessel departed from Panganiban (Mischief) Reef on July 26. 

It has since passed through several critical locations including Ayungin (Second Thomas) Shoal, Raja Soliman Shoal (Boxall Reef), Bulig (First Thomas) Shoal, Hasa Hasa (Half Moon) Shoal, and Abad Santos Shoal, before it eventually reached Escoda Shoal.

Escoda Shoal is located just 75 nautical miles or about 140 kilometers from Palawan. It serves as the rendezvous point of the Armed Forces of the Philippines (AFP) whenever it conducts resupply missions to the BRP Sierra Madre outpost in Ayungin Shoal.

The PCG did not indicate why the Chinese research vessel was emitting irregular AIS transmissions while navigating the WPS.

AIS serves as the “eyes” of the ships as it helps them communicate with each other while sailing at sea, preventing potential maritime incidents. It transmits a ship's position to other vessels so they are aware of each other’s position.

Manila and Beijing have been working to de-escalate the tension in the WPS through diplomatic talks especially after the violent June 17 resupply mission where a Filipino sailor lost his thumb.
