  • •The Chinese vessel JIA HAI KE 7 is accused of AIS spoofing to hide its movements.
  • •PCG confirmed the vessel's unauthorized presence near critical undersea communication cables.
  • •The situation highlights ongoing maritime tensions between the Philippines and China.

The Philippine Coast Guard (PCG) has reported that the Chinese research vessel JIA HAI KE 7 was detected spoofing its Automatic Identification System (AIS) data while loitering off Itbayat, Batanes. The vessel was confirmed to be holding position 38 nautical miles northwest of Itbayat, within the Philippine exclusive economic zone. The PCG issued multiple radio challenges to the vessel, which went unanswered, raising concerns over unauthorized marine scientific research activities. The vessel's AIS data indicated impossible movements, suggesting deliberate concealment of its true location. The PCG highlighted the potential military implications of the data collected by the vessel, which operates in critical submarine cable corridors linking the Philippines to Northeast Asia. The PCG will continue monitoring the vessel and has stated it will take necessary measures to protect its maritime zone. The situation reflects ongoing tensions between the Philippines and China regarding territorial waters.
