Senate President Pro Tempore Jinggoy Ejercito Estrada said the recent sighting of the China Coast Guard’s largest vessel off the coast of Zambales “is deeply concerning.”

Estrada pointed this out as he also took note of the earlier recovery of an underwater drone off the coast in Masbate province.

“These repeated incursions and unauthorized activities in our waters raise significant concerns about China’s respect for international law and the sovereignty of the Philippines,” Estrada said in a statement released on Monday, January 6.

“Such incidents emphasize the need for ongoing vigilance and a firm commitment to protecting our territorial integrity and maritime rights,” he stressed.

The head of the Senate Committee on National Defense and Security, likewise, commended the Philippine Coast Guard for their prompt and effective response to the presence of the CCG vessel which they have referred to as “The Monster.”

“Their vigilance and unwavering dedication to safeguarding our maritime territories reflect their commitment to the safety and security of our fisherfolk and coastal communities,” Estrada further said.

Estrada said the government should remain resolute in warding off such activities and protecting the country’s territorial integrity and maritime rights.

“Hindi tayo matitinag, gaano man kabigat ang pwersang humahamon sa integridad ng teritoryo natin (We will not be moved, no matter how heavy the forces that challenge the integrity of our territory),” he said.

“As a peace-loving nation, we remain committed to defending our sovereignty while pursuing diplomatic solutions to resolve these issues, ensuring adherence to international laws and agreements,” he reiterated.

Earlier, Senate Majority Leader Francis Tolentino formally filed a resolution asking the Senate Special Committee on Philippine Maritime and Admiralty Zones to conduct an investigation into the discovery of a submersible drone off the coast of Barangay Inawaran, San Pascual, Masbate.

Tolentino said it is necessary to hold a Senate inquiry into the matter to find out about the device’s origins, its operational capabilities and if it complies with the country’s existing maritime laws.

He noted that the six-foot drone, which is made from PVC and metal, and functioning as a remote-controlled electronic device is possibly used for communication and navigation. Authorities also said the drone was already deactivated when it was discovered.

Tolentino pointed out that if a drone is confirmed to be of foreign origin, it must comply with Philippine law and will be subjected to examination by Philippine authorities to ensure compliance with these regulations.

“Drones used for marine scientific research within Philippine maritime zones must comply with the Philippine Maritime Zones Act, “ Tolentino said.
