MANILA, Philippines — Vessels in Subic Bay marked the 10th anniversary of the 2016 South China Sea arbitral award with a water salute and a coordinated horn-blowing ceremony, the Philippine Navy said Sunday, July 12.
Ships across the country sounded 10 long blasts to commemorate the landmark ruling, which rejected China's sweeping maritime claims and affirmed the Philippines' rights in parts of the West Philippine Sea.
"As ships across the country sound 10 long blasts, we commemorate a decade of the rule of law over force, express our national solidarity, uphold our sovereignty, and reaffirm our steadfast commitment to the rules-based maritime order," the Philippine Navy said.
The symbolic activity in Subic Bay included vessels from the Philippine Navy, U.S. Navy, National Mapping and Resource Information Authority and several commercial ships.
Twenty-eight ships in Subic joined the simultaneous horn-blowing. Separate reports said tugboats also staged the water salute, according to a GMA News report.
Award anniversary. The ceremony came as the Philippines and 13 other countries issued a joint statement reaffirming the 2016 arbitral award as "final, legally binding, and definitive" between the Philippines and China on the maritime entitlements and claims addressed by the tribunal.
The joint statement was released by the governments of the Philippines, United States, Australia, Canada, Estonia, Germany, Italy, Japan, Latvia, Lithuania, New Zealand, Romania, Slovenia and the United Kingdom.
The countries reaffirmed that there is no legal basis for China's expansive maritime claims in the South China Sea, including claims based on "historic rights."
They also reiterated their opposition to the use of coast guard, military and maritime militia forces "to harass, obstruct, or intimidate lawful operations by other States at sea or in the air."
The July 12, 2016 award was issued by an arbitral tribunal constituted under the United Nations Convention on the Law of the Sea. It invalidated China's sweeping claims in the South China Sea that exceeded maritime entitlements under international law and affirmed the Philippines' sovereign rights and maritime entitlements within its exclusive economic zone.
China has refused to recognize the award.

Executive Summary

Vessels in Subic Bay observed a ceremony marking the tenth anniversary of the 2016 South China Sea arbitral award by sounding ten long blasts of the horn. This action was intended to commemorate the ruling which rejected China's maritime claims and affirmed Philippine rights in parts of the West Philippine Sea. The ceremony involved vessels from the Philippine Navy, the U.S. Navy, the National Mapping and Resource Information Authority, and several commercial ships, with reports indicating tugboats also participated in the salute. This observance occurred as the Philippines and thirteen other nations issued a joint statement reaffirming the 2016 award as legally binding between the Philippines and China regarding maritime entitlements. The joint statement asserted that China has no legal basis for its expansive maritime claims in the South China Sea, including those based on historic rights, and opposed the use of Coast Guard or maritime militia forces to harass lawful operations.

Full Take

The event demonstrates a strategic use of symbolic action to reinforce a specific legal and sovereignty narrative. The coordinated maritime salute functions not merely as remembrance but as a public declaration of adherence to an established international legal mechanism—the arbitral ruling—as the foundation for national policy, effectively translating abstract legal judgments into tangible, visible acts of state solidarity. The inclusion of various international partners in the joint reaffirmation highlights an attempt to build a broader coalition supporting this specific interpretation of maritime entitlements. The tension arises from the disparity between the asserted "final, legally binding" status of the award and China's explicit refusal to recognize it, creating a conflict between established international legal precedent and unilateral geopolitical action. This pattern suggests that cognitive sovereignty is actively being constructed through collective symbolic behavior, even when confronting non-recognition from a major actor. The implication for agency lies in the ability of states to mobilize international recognition—or public alignment—to shape the operational reality on the water.
