China's Foreign Ministry on the 10-year anniversary of the South China Sea Arbitration Award rejected coordinated international commemorations of the 2016 ruling, asking whether governments that backed the award had thereby voluntarily waived their own maritime rights.

The ministry's statement, issued on July 12 to mark a decade since the Arbitral Tribunal constituted under Annex VII of the United Nations Convention on the Law of the Sea delivered its findings, accused unnamed states of generating "joint hype" around the decision.

The Foreign Ministry did not identify the specific acts of endorsement it was targeting, nor did it name any government whose maritime posture it now questions. The remarks, reported by the state-affiliated Global Times, refer generally to "those countries supporting 'award'."

What the 2016 award held

The July 12, 2016 award remains the principal international legal instrument addressing maritime disputes in the South China Sea. In Republic of the Philippines v. People's Republic of China, a tribunal constituted under Annex VII of UNCLOS held that:

• China's nine-dash-line claim has no legal effect under the convention
• None of the Spratly Island features China occupies within the nine-dash line are islands entitled to a 200-nautical-mile exclusive economic zone
• China violated the Philippines' sovereign rights by interfering with fishing and oil exploration near Scarborough Shoal

The award was rendered in The Hague. China refused participation in the proceedings and rejected the award on the day of its release as "null and void," a position it has maintained every year since on the anniversary.

What is China asking now?

The Foreign Ministry's central question — whether states that have publicly supported the award have "voluntarily waived maritime rights" — frames continued endorsement of the 2016 findings as a potential legal admission.

The ministry's reasoning runs as follows: a state that treats the tribunal's conclusions as binding on others implicitly concedes that its own historic or asserted maritime claims cannot override UNCLOS-based delimitation.

The framing shifts diplomatic pressure onto any capital that has reaffirmed the award in recent anniversary statements. Under the Chinese formulation, those acts of endorsement may be cited in future bilateral talks or in disputes in which the supporting state asserts its own historic claims against a third party.

The ministry has not specified which acts it considers to constitute a waiver, nor has it indicated whether the question is rhetorical or intended to inform a formal legal claim.

Practical consequences for practitioners

For legal advisers, shipping operators and energy companies active in the South China Sea, the anniversary statement signals that Beijing will continue to treat the 2016 award as legally inert within its own posture while pressing third states to justify any continued reliance on it.

Clients should expect renewed Chinese official commentary framing foreign acquiescence in the award as a waiver of rights in any future negotiations. Marine insurers and port-state control authorities should note that China is unlikely to change its enforcement posture in disputed waters.

The statement follows an established pattern of Chinese July 12 commemorations from Beijing's perspective. It does not announce any new policy measure, nor does it modify China's territorial or maritime claims as set out in official maps.
