Dismantling the floating barrier that China installed at Scarborough Shoal or Bajo de Masinloc is a matter for President Ferdinand Marcos Jr. to decide, a Philippine Coast Guard official said yesterday.

Commodore Jay Tarriela, PCG spokesperson for the West Philippine Sea, said they had reported the discovery of the 300-meter barrier to the National Task Force for the West Philippine Sea, or NTF-WPS.

"Should the NTF-WPS recommend to the President the actions to be taken, the PCG, the Bureau of Fisheries and Aquatic Resources, and even the Armed Forces of the Philippines would comply," Tarriela said.

Tarriela was apparently reacting to the call made by Senate President Juan Miguel Zubiri for the PCG to remove the barrier as it poses a danger to Filipino fishermen and keeps them from the shoal's rich fishing grounds.

Tarriela, however, said the PCG had yet to consult with Mr. Marcos and other officials of the national government on what to do about the barrier.

The PCG said three China Coast Guard inflatable boats backed by a Chinese maritime militia vessel installed the floating barrier.

Also on Monday, the Department of Foreign Affairs vowed to press the Philippines' sovereignty over Scarborough Shoal.

"We will take all appropriate measures to protect our country's sovereignty and the livelihood of our fisherfolk," the DFA said.

"Bajo de Masinloc is an integral part of the Philippines over which we have sovereignty and territorial jurisdiction according to UNCLOS (United Nations Convention on the Laws of the Sea)," the DFA said.

In 2012, Chinese and Philippine vessels faced each other in a standoff at the shoal, which was defused when the Philippines withdrew its ships, which China did not do with its ships despite an agreement to do so.

China has since maintained control of the shoal even after a 2016 ruling of the Permanent Court of Arbitration deemed the shoal to be part of the Philippines' 200-nautical-mile exclusive economic zone in the West Philippine Sea.

The landmark ruling, which also dismissed as illegal China's claim to nearly the entire South China Sea, arose from a case filed by the Philippines before the arbitral court in 2013. China, however, has refused to abide by the ruling.

"The 2016 Arbitral Award affirms it (Bajo de Masinloc) as a traditional fishing ground for Filipino fisherfolk," the DFA pointed out.

"China's reported installation of barriers and its negative impact on the livelihood of Filipino fisherfolk or any other activity that infringes on the Philippines' sovereignty and jurisdiction in Bajo de Masinloc are violations of international law, particularly UNCLOS and the Arbitral Award," it added.

The installation of the barrier was roundly criticized by European Union Ambassador to the Philippines Luc Veron, who described it as "deeply concerning."

In a tweet, Veron said the "floating barrier is dangerous, detrimental to the livelihood of Philippines fishermen, and disregards the peace-driven objectives of UNCLOS."
