The arbitration award, maritime enforcement, military construction, and historical-rights narratives continue to conflict.
Case chronologyFull case chronology and key recordsExpand
The Philippines initiated UNCLOS arbitration
The Philippines sought rulings on China's historic-rights claims, the legal status of maritime features, and conduct within the Philippine exclusive economic zone.
The tribunal upheld jurisdiction over multiple submissions
China declined to participate and argued the dispute concerned sovereignty and delimitation; the tribunal distinguished territorial sovereignty from interpretation of UNCLOS.
The final award rejected a legal basis for broad historic rights within the nine-dash line
The tribunal also found that relevant Spratly features could not generate exclusive economic zones and that some Chinese construction and enforcement activities violated Philippine rights.
China declared the award null and continued to reject it
China's Foreign Ministry said the award had no binding force and insisted on bilateral negotiation. With no direct enforcement mechanism, the legal result and maritime power politics continued in parallel.

The Philippines starts arbitration
On 22 January 2013, the Philippines invoked Annex VII of the United Nations Convention on the Law of the Sea. It did not ask the tribunal to decide island sovereignty. Its submissions concerned the legal basis of China’s historic-rights claim inside the nine-dash line, the maritime entitlements of features in the Spratlys and the legality of Chinese enforcement and construction inside the Philippine exclusive economic zone. China refused to participate, arguing that the dispute concerned sovereignty and delimitation outside compulsory arbitration. [1] [2]
On 29 October 2015, the tribunal accepted jurisdiction over several submissions and explicitly excluded territorial sovereignty and maritime delimitation. On 12 July 2016, the final award found no UNCLOS basis for broad historic rights beyond the convention, held that the relevant Spratly features could not generate exclusive economic zones and found that some Chinese enforcement, reclamation and construction violated Philippine rights or damaged the marine environment. Annex VII permits proceedings to continue when one party is absent, but the tribunal still had to establish jurisdiction and an evidentiary basis. [1]
China’s response and maritime conduct
The Foreign Ministry called the award “null and void” and without binding force, maintained China’s sovereignty and maritime claims and demanded direct negotiation. Coast guard, maritime and island-building activity continued to form the dispute’s physical background. A tribunal can define legal rights but has no maritime force of its own. The CCP exploits that gap by combining rejection of the award with control at sea. [2]
Legal judgment versus power at sea
The award clarified the legal limits of historic rights, maritime features and conduct inside an exclusive economic zone. It did not stop resupply obstruction, coast guard confrontations, construction or diplomatic pressure. Beijing repeats historic-rights and sovereignty language to domestic audiences and presents arbitration as foreign containment. Philippine governments have varied in how strongly they invoke the award while managing relations with China, reinforcing Beijing’s belief that time and force can dilute legal costs.
Evidence boundary
The arbitration record establishes the Philippine submissions, jurisdictional reasoning and final award. Foreign Ministry statements establish China’s rejection. Public evidence does not identify the internal order behind each maritime action, and the award must not be described as a ruling on territorial sovereignty. The political choice is nevertheless clear: the CCP uses non-recognition to support continued maritime expansion.
