The arbitration award, maritime enforcement, military construction, and historical-rights narratives continue to conflict.

The Philippines Filed for Arbitration After the Scarborough Standoff
In April 2012, a Philippine naval vessel confronted Chinese fishing boats near Scarborough Shoal. Chinese maritime-surveillance ships intervened, and vessels from both sides remained in a prolonged standoff. The Philippines eventually withdrew its ships while Chinese government vessels maintained their presence. Manila lost effective access around the shoal.
The disparity in maritime power left the Philippines unable to force Beijing to withdraw at sea. In January 2013, Manila began arbitration under Annex VII of the United Nations Convention on the Law of the Sea. It asked a tribunal to decide the legal effect of China's historic-rights claims inside the nine-dash line, the status of several maritime features, and the legality of Chinese activities inside the Philippine exclusive economic zone. The Philippines did not ask the tribunal to decide sovereignty over islands or delimit a maritime boundary. [1]
China refused to participate and argued that the tribunal lacked jurisdiction. Beijing insisted on bilateral negotiation. Its absence did not halt the case. UNCLOS permits proceedings to continue when one party refuses to appear, while requiring the tribunal to establish jurisdiction and the factual basis for its conclusions.
The 2016 Award Rejected Historic Rights Inside the Nine-Dash Line
The tribunal issued its award on July 12, 2016. It found that UNCLOS comprehensively allocates maritime entitlements and that China had no legal basis for historic rights to resources beyond those limits inside the nine-dash line. It also concluded that none of the relevant Spratly features could generate a full 200-nautical-mile exclusive economic zone. Features above water at high tide could produce at most a 12-mile territorial sea, while low-tide elevations produced no maritime zone of their own.
The award classified Mischief Reef and Second Thomas Shoal as low-tide elevations within the Philippine exclusive economic zone. It found that China had violated Philippine sovereign rights by interfering with fishing and petroleum exploration, building artificial islands, and failing to prevent Chinese fishing in relevant waters. The tribunal also found severe harm to coral-reef environments from large-scale island construction. [1]
The Philippine government welcomed the decision and described it as an affirmation of UNCLOS while urging restraint. [4] China's Foreign Ministry declared the award null, void, and without binding force, refusing to accept or recognize it. [2] China had joined UNCLOS, yet rejected its dispute process when the result obstructed Beijing's expansion.
Island Construction Changed the Facts at Sea
China was already dredging and building on several Spratly features while the arbitration proceeded. Satellite analysis by the Asia Maritime Transparency Initiative estimates that China created about 3,200 acres of new land in the Spratlys from 2013 onward. It installed runways, harbors, radar, and other dual-use facilities at Fiery Cross, Subi, Mischief, and additional reefs. [3]
Artificial islands do not acquire new territorial seas or exclusive economic zones under UNCLOS. They still provide logistics, surveillance, and rapid-deployment bases for coast guard, naval, and maritime-militia vessels. The CCP converted a legally unsupported claim into physical control by ships and installations. Fishers and resupply crews from neighboring states encounter water cannon, interception, collision risks, and persistent shadowing rather than an academic disagreement.
Beijing exploits the enforcement weakness of international adjudication. A tribunal can interpret law but has no coast guard or navy. The Philippines and other coastal states must pay the military and economic cost of exercising rights already recognized in law. China's larger fleet repeatedly forces smaller states to choose restraint, after which Beijing presents that restraint as acquiescence to Chinese control.
Propaganda Recasts Expansion as Chinese Victimhood
Official Chinese messaging portrayed the arbitration as an American plot, a Philippine provocation, and intervention by an illegal tribunal. It repeated that China's South China Sea rights existed since ancient times while avoiding the award's detailed treatment of historic resource claims and the legal status of maritime features. A complicated dispute under the law of the sea became a test of national dignity, and criticism of expansion became containment of China.
That narrative disciplines domestic politics. By depicting any maritime compromise as national humiliation, the CCP closes the space in which it could accept legal constraint. Military spending, coast-guard expansion, and fortified outposts become defenses of ancestral territory. The public is encouraged to demand tougher action while being denied open scrutiny of strategic costs, conflict risks, and the legal foundation of historical claims.
China's national-security white paper places territorial integrity, maritime interests, and CCP leadership inside a comprehensive security framework. [6] Maritime disputes are therefore absorbed into the party center's account of regime security and national rejuvenation. Professional diplomacy and legal analysis remain subordinate to strategic objectives set under Xi Jinping.
A Legal Victory Did Not Automatically End Coercion
The Philippines obtained a clear award in 2016 and adjusted its China policy under successive governments. Economic promises, trade and investment relationships, and pressure at sea all affected Manila's willingness to enforce its rights. Beijing does not need to erase the text of the award. It can weaken the decision on the water by keeping the cost of implementation high.
The arbitration exposes the CCP's selective approach to international rules. When a rule supports China, Beijing demands respect for sovereignty and treaties. When a rule limits Chinese expansion, it declares the outcome invalid and uses superior force to create a new reality. This conduct reflects a one-party regime that treats international law as an instrument rather than a constraint.
The award remains important because it separates sovereignty disputes from maritime entitlements and prevents the nine-dash line's ambiguity from becoming accepted law. Its lasting effect depends on sustained publication of evidence, collective defense of navigation and resource rights, and diplomatic and economic costs for coercion. Concessions to the CCP will not produce stability. They demonstrate that physical pressure can bury legal rights.
