Tribunal Rules: China's South Sea Claims Don't Hold Water

The law says what we always knew: China is overstepping in the South China Sea.


The Arbitration Tribunal at the Hague regarding the UN Convention on the Law of the Sea (UNCLOS) has just made a big splash with its landmark ruling in PCA Case No. 2013-19—the South China Sea Arbitration (The Republic of the Philippines v. The People’s Republic of China).

“The Philippines welcomes the issuance today . . . on the arbitration proceedings initiated by the Philippines with regard to the South China Sea,” Foreign Affairs Secretary Perfecto Yasay rightly told the press this morning.


His welcoming is rippling across the Asia-Pacific and around the world: this is a great victory for Manila, Washington and all other parties committed to international law—and for the peaceful, open global system that they rightly support.

The Verdict

The Tribunal’s full-length “award” document is a five-hundred-page doorstop, readily digestible by only the most determined of legal experts. Many will be struck by the fact that the Tribunal found Beijing to have violated no fewer than fourteen UNCLOS provisions, six International Regulations for Preventing Collisions at Sea (COLREGS) rules and one general rule of international law.

Fortunately for nonspecialists, the Tribunal’s the bottom line is clear: China’s sweeping yet undefined South China Sea claims don’t hold water.

Here are the related principal findings:

1. China’s “nine-dash-line” and related “historic rights” claims have no legal basis.

• Key wording: “The Tribunal concluded that there was no legal basis for China to claim historic rights to resources within the sea areas falling within the ‘nine-dash line.’”

• Significance: “My ancestors fished there” simply doesn’t cut it—for any country, except in territorial seas, e.g., surrounding Scarborough Reef.

2. The Spratly features that China claims, individually or collectively, cannot generate an Exclusive Economic Zone (EEZ) for Beijing.

• Key wording: “the Tribunal concluded that none of the Spratly Islands is capable of generating extended maritime zones. . . . the Spratly Islands cannot generate maritime zones collectively as a unit. . . . none of the features claimed by China was capable of generating an exclusive economic zone.”

• Significance: Of critical legal importance, (in applying the 121(3) rule concerning islands and rocks) the tribunal has ruled that the largest feature, Taiwan-occupied and China-claimed Itu Aba, is a “rock” and hence not entitled to an EEZ or continental shelf. There are therefore no maritime boundary delimitation issues to deal with here, scuttling China’s vehement protests that there are. In fact, there is not much question about boundaries at all, only baseline issues for low-tide elevations (LTEs) within territorial seas of some features.

3. China has violated sovereign rights of the Philippines, illegally interfered with traditional fishing rights of the Philippines, and unlawfully created serious risk of collision by engaging in unsafe navigational practices and obstructing Philippine vessels.

• Key wording: “Having found that certain areas are within the exclusive economic zone of the Philippines, the Tribunal found that China had violated the Philippines’ sovereign rights in its exclusive economic zone by (a) interfering with Philippine fishing and petroleum exploration, (b) constructing artificial islands and (c) failing to prevent Chinese fishermen from fishing in the zone. The Tribunal also held that fishermen from the Philippines (like those from China) had traditional fishing rights at Scarborough Shoal and that China had interfered with these rights in restricting access. The Tribunal further held that Chinese law enforcement vessels had unlawfully created a serious risk of collision when they physically obstructed Philippine vessels.”

• Significance: All countries have their own sovereign rights, and China must honor its constant claims not to interfere with them.

4. China has violated obligations to preserve and protect the maritime environment generally, conserve fishing stocks, and prevent Chinese fishermen from large-scale harvesting of endangered species. Experts find major damage to reefs.

• Key wording: “The Tribunal . . . found that China had caused severe harm to the coral reef environment and violated its obligation to preserve and protect fragile ecosystems and the habitat of depleted, threatened, or endangered species. The Tribunal also found that Chinese authorities were aware that Chinese fishermen have harvested endangered sea turtles, coral, and giant clams on a substantial scale in the South China Sea (using methods that inflict severe damage on the coral reef environment) and had not fulfilled their obligations to stop such activities.”

• Significance: Perhaps China’s well-documented devastation of reefs and other fragile natural treasures will finally galvanize foreign environmental organizations, which have long been strangely silent on this subject, to speak out.

5. China’s industrial-scale land reclamation and feature augmentation violates obligations during dispute resolution proceedings and does not confer any additional maritime legal rights to the features themselves.

• Key wording: “The Tribunal found . . . that China’s recent large-scale land reclamation and construction of artificial islands was incompatible with the obligations on a State during dispute resolution proceedings, insofar as China has inflicted irreparable harm to the marine environment, built a large artificial island in the Philippines’ exclusive economic zone, and destroyed evidence of the natural condition of features in the South China Sea that formed part of the Parties’ dispute.”

• Significance: Beijing is aggravating and extending disputes in violation of UNCLOS and international law more broadly. “Fake it till you make it” has no validity in international law.

The Larger Concern

China doesn’t have to like the Tribunal’s ruling, but—having ratified UNCLOS—it is legally bound to respect it in practice.

Any failure to do so will tarnish Beijing’s reputation badly and sharply increase the already-growing costs it faces in the court of public opinion. It will do so by stoking broader fears that as it becomes increasingly powerful China will:

• Abandon previous restraint in word and deed

• Bully its smaller neighbors

• Implicitly or explicitly threaten the use of force to resolve disputes

• Attempt to change precipitously—or else run roughshod over—important international norms that preserve peace across Asia and underwrite the global system on which mutual prosperity depends.

Rep. J. Randy Forbes, chairman of the House Armed Services Seapower and Projection Forces Subcommittee and cochairman of the Congressional China Caucus, summed this up cogently in a press release this morning:

“Today is China’s moment to show, once and for all, the reality of its claim to be a ‘responsible stakeholder’ in the international community. Failure to fully respect the ruling of the arbitration panel would not only expose China’s belief in a ‘might makes right’ philosophy for all the world to see—it would also profoundly fray the post-1945 international order that Beijing has been chipping away at for nearly a decade. The United States must stand steadfastly on the side of international law and the peaceful resolution of disputes, and hold China to account for its behavior following this ruling.”

Meanwhile, all parties concerned must remain vigilant prevent China from destabilizing a vital yet vulnerable region that remains haunted by history and, worse still, grabbing with coercion or force what it could not—and now clearly cannot—obtain legally.

The Risks

In particular, the United States and its regional partners need to be prepared for China to utilize a tailored tool that all too few people understand, or even recognize.

For years now, China has been surreptitiously pushing territorial claims against weaker neighbors using its Maritime Militia or “Little Blue Men,” roughly equivalent at sea to Putin’s “Little Green Men” on land. This Maritime Militia, the world’s largest, is China’s Third Sea Force, after the world’s second-largest blue-water navy and largest blue-water coast guard. The “Chinese fishermen” and fishing vessels under military-control within this irregular sea force include precisely the ones that China has used to interfere with Philippine fishermen’s “traditional fishing rights,” including “at Scarborough Shoal”—violations that the tribunal has roundly and soundly condemned.

Now the Third Sea Force offers a tempting tool for Beijing to disrupt U.S. Freedom of Navigation Operations in the South China Sea, which Beijing bitterly opposes for emboldening its neighbors. It can also be used to punish the Philippines for initiating the legal case, and to deter any other neighbors (like Vietnam) which might consider follow-on submissions.

China’s Third Sea Force has already played a key role in a wide range of Chinese incidents and skirmishes with foreign maritime forces throughout the South China Sea. These include China’s:

1. 1974 seizure of the western portion of the Paracel Islands from Vietnam

2. 2009 harassment of the U.S. survey ship Impeccable

3. 2011 sabotage of two Vietnamese hydrographic vessels

4. 2012 seizure of Scarborough Shoal from the Philippines

5. 2014 repulsion of Vietnamese vessels from disputed waters surrounding its HYSY-981 Oil Rig

Yet, China’s Maritime Militia has not yet been mentioned in any public U.S. reports or in any public statements by Washington-based U.S. officials. In particular, the utter failure of the Pentagon’s 2016 China report to mention the Maritime Militia in any way whatsoever was a major missed opportunity. If the U.S. government (with all its resources and capabilities) has not yet begun to address this challenge openly and proactively, how can it expect its Asian partners to do so? And how can it expect Beijing to be deterred from using its Third Sea Force in new, nonlegal ways?
