Exclusive: Japan voices concern over West PH sea tensions, backs legally binding ASEAN code of conduct

Metro Manila, Philippines - Japan expressed concern over rising tensions in the West Philippine Sea and called for adherence to international law, Japanese Ambassador Endo Kazuya said, underscoring support for the Philippines and a legally binding ASEAN Code of Conduct (COC).

“Japan’s position over the South China Sea issue is firm and consistent. We are very much concerned about the ongoing provocations and escalations of tensions in that sea area,” Endo told NewsWatch Plus in an exclusive interview.

Recent incidents, including collisions between Chinese and Philippine vessels near Scarborough Shoal and risky maneuvers by Chinese fighter jets, have heightened concerns about maritime safety and freedom of navigation. Endo said these undermine regional stability and prosperity.

“The rule of law in the maritime sphere is the foundation of stability and prosperity in this region,” he said.

Japan, while not a claimant in the disputes, considers itself an important stakeholder and maintains a consistent position in supporting Philippine claims based on the 2016 arbitral ruling.

“It is very important for like-minded countries to show a resolute commitment to the rule of law in the maritime sphere,” Endo added, citing joint maritime cooperative activities with other nations to reduce the risk of miscalculation at sea.

The ambassador also called on the Association of Southeast Asian Nations (ASEAN) to conclude the South China Sea Code of Conduct, emphasizing that it should be effective, substantive, and fully compliant with the United Nations Convention on the Law of the Sea (UNCLOS).

“I think it is very important for the COC to respect all the legitimate rights and interests of all stakeholders involved in this matter,” Endo said.

Japan has repeatedly urged regional partners to maintain a collective stance on upholding maritime law and has participated in various forums to support this goal. Endo said these efforts send a clear signal to all parties that provocations and unilateral actions will be closely monitored by the international community.

“Although Japan is not a claimant, we recognize ourselves as an important stakeholder on this matter and will continue to maintain our consistent positions,” he said.

The ambassador noted that continued cooperation among like-minded countries, including the Philippines, the United States, and other regional partners, is essential to minimize the risk of conflict and to promote dialogue based on legal frameworks.

“Japan will continue watching the situation and the developments surrounding the Code of Conduct very closely,” Endo said.
