  • The award, issued by the Permanent Court of Arbitration, invalidated most of China's maritime claims in the region.
  • The Philippine Department of National Defense reaffirmed commitment to uphold the award.
  • Support for the ruling has increased over the decade since its issuance.

Overview

On the tenth anniversary of the 2016 Arbitral Award concerning the South China Sea, a report states that at least 44 countries have openly supported the ruling that invalidated China's expansive maritime claims. The Philippines continues to assert its rights under the decision and the United Nations Convention on the Law of the Sea (UNCLOS), with growing international backing.

What Happened

According to a July 2026 report, at least 44 countries, including 27 specifically calling for respect for the award and 17 explicitly backing it, support the 2016 decision issued by the Permanent Court of Arbitration in The Hague.

The arbitral tribunal found that China's sweeping claims over most of the South China Sea lacked legal basis under UNCLOS.

The Philippine Department of National Defense issued a statement reaffirming its commitment to the award and to enforcing maritime rights in its exclusive economic zone.

The statement emphasized ongoing efforts to document and expose activities deemed illegal under international law in the disputed waters.

Context

The 2016 arbitral ruling arose from a case brought by the Philippines against China before the Permanent Court of Arbitration. The tribunal ruled in favor of the Philippines, rejecting China's claims over much of the South China Sea.

China has consistently rejected the ruling, though its legal validity under the Convention on the Law of the Sea is cited by supporting nations.

Why It Matters

  • Growing international support may strengthen efforts to uphold the maritime rights established by the arbitral award.
  • The report highlights continued international attention and pressure regarding enforceability of international legal decisions, particularly in high-stakes maritime disputes.
