THE PHILIPPINES should push its regional peers to come up with a coordinated position against China鈥檚 incursions in the South China Sea, according to a senator.

The Department of Foreign Affairs (DFA) should lead the push, Senator Ana Theresia Hontiveros-Baraquel said in a statement on Wednesday, as foreign ministers of the Association of Southeast Asian Nations (ASEAN) meet on August 2 to 6.

鈥淎SEAN should stand as one,鈥 she said. 鈥淲hen it comes to China鈥檚 belligerent actions in the West Philippine Sea, ASEAN鈥檚 principle of noninterference does not apply,鈥 she added, referring to parts of the South China Sea within the country鈥檚 exclusive economic zone.

鈥淪hould China impede freedom of navigation in the entire South China Sea, it is not only the Philippines that will be gravely affected, but also the whole region,鈥 Ms. Hontiveros said. 鈥淚f the Philippines loses this diplomatic battle against China, the ASEAN loses too.鈥

Other ASEAN claiming parts of the disputed waterway have also been pushing back against China. Malaysia this year filed a diplomatic protest against China after Chinese aircraft were spotted over the South China Sea, off Borneo.

Last year, Vietnam was reported to have been exploring raising an international arbitration case against China.

鈥淭he ASEAN must actively exhaust all legal and diplomatic means to resist China鈥檚 excessive claims,鈥 Ms. Hontiveros said. 鈥淏eing passive does not help our case, especially in the face of an aggressor. China deliberately targets weaker states unable to effectively resist, thus the need for unified and concerted action.鈥

She said the region is home to some of the best and brightest minds in international law and diplomacy, 鈥渟o let鈥檚 pool these talents together and put China in her place.鈥澛

DFA has filed more than 100 diplomatic protests against China since 2016 because of its 鈥渋ncessant deployment, prolonged presence and illegal activities鈥 in the South China Sea,鈥 the lawmaker said. 鈥淓ven then, Chinese fishing vessels and maritime militia vessels continue to increase.鈥

China has denied having deployed militia vessels at sea, saying these were fishing vessels.

Ms. Hontiveros said China鈥檚 presence in the waterway had destroyed marine life.

The Philippines loses P33.1 billion yearly or more than P200 billion in the past seven years, according to the University of the Philippines Marine Science Institute.

Foreign Affairs Secretary Teodoro L. Locsin, Jr. on Tuesday said a 2016 landmark arbitral ruling against China could help settle the sea dispute, which can be resolved peacefully by following international law.

The ruling should be followed by all since it was based on the United Nations Convention on the Law of the Sea, he said in a speech at the ASEAN post-ministerial conference session with China. 鈥 Alyssa Nicole O. Tan
