The international foreign policy establishment loves an anniversary. They get to dust off old press releases, assemble a coalition of the willing, and issue sternly worded joint statements that feel important but achieve absolutely nothing.
The tenth anniversary of the 2016 Arbitral Award on the South China Sea is the perfect example. Fourteen nations and the European Union just lined up to reaffirm that the ruling is "legally binding." They want you to believe this is a triumph of the international rules-based order. They want you to think that a decade of diplomatic solidarity has boxed Beijing into a corner. If you found value in this article, you might want to look at: this related article.
It is a comforting narrative. It is also completely detached from reality.
The hard truth nobody in Washington, Brussels, or Manila wants to admit out loud is that the 2016 ruling has failed its primary objective. It has not deterred a single island-building project. It has not stopped a single maritime skirmish. By treating a piece of paper as a shield against hard naval power, the West has spent ten years weaponizing a legal ghost while Beijing built a permanent military reality. For another look on this development, see the recent update from NPR.
The Illusion of Enforceability
Let us correct a fundamental misunderstanding of international law that mainstream journalists consistently get wrong.
The Permanent Court of Arbitration (PCA) is not a court in the way ordinary citizens understand it. It has no police force. It has no navy. It possesses zero enforcement mechanisms. When the tribunal ruled in favor of the Philippines, declaring China’s "nine-dash line" historical claims invalid under the United Nations Convention on the Law of the Sea (UNCLOS), it created a moral victory, not a physical barrier.
International law only works when the parties involved value their reputation within that specific legal framework more than the geopolitical territory at stake.
China made its position clear from day one: non-participation, non-acceptance. Beijing looked at the tribunal, shrugged, and kept dredging sand.
Imagine a scenario where a local code enforcement officer tells a billionaire that his new mansion violates zoning laws, but the officer has no power to issue fines, arrest anyone, or tear down the building. The billionaire is going to finish the mansion. That is the South China Sea in a nutshell.

Why More Signatories Do Not Equal More Power
The competitor articles on this milestone beat the same tired drum: Look at the growing list of nations signing on! Fourteen countries plus the EU! The coalition is expanding!
This is a classic vanity metric. It is the diplomatic equivalent of getting likes on a social media post instead of making a sale.
Does a supportive statement from a landlocked or distant European nation change the tactical calculus for a Philippine resupply mission to Second Thomas Shoal? Not in the slightest. When the China Coast Guard deploys water cannons and military-grade lasers against wooden resupply boats, an EU press release does not deflect the water.
This performative diplomacy actually harms the nations it is supposed to help. It creates a false sense of security. It allows Western capitals to check the "Southeast Asia stability" box without committing the heavy, sustained naval assets required to actually alter Beijing’s cost-benefit analysis.
I have spent years watching defense analysts celebrate these symbolic victories while the actual geography of the region shifts permanently. We are trading physical positioning for rhetorical consistency. It is a terrible trade.
The Fatal Flaw in the West's UNCLOS Obsession
The supreme irony of the United States leading the cheerleading squad for the 2016 Arbitral Award is that Washington has still not ratified UNCLOS.
For decades, the U.S. Senate has refused to ratify the treaty, citing concerns over national sovereignty and deep-seabed mining regulations. Yet, American diplomats routinely lecture the rest of the world about adhering to a treaty they refuse to formally bind themselves to.
This hypocrisy is not lost on the Global South, and it is certainly not lost on Beijing. It allows Chinese state media to easily dismiss Western pressure as arrogant, do-as-I-say neo-colonialism.
Furthermore, the obsession with the 2016 ruling ignores how gray-zone warfare actually works. China does not need to formally reject UNCLOS in every day-to-day interaction; they simply operate in the spaces between total peace and overt military aggression.
- Maritime Militia: Deploying hundreds of "fishing vessels" that are actually state-funded paramilitary forces to swarm reefs.
- Laser Harassment: Using blinding, non-lethal lasers against aircraft and cutters to disrupt operations without triggering mutual defense treaties.
- Naval Blockades by Attrition: Surrounding features like Sabina Shoal or Second Thomas Shoal to starve out outposts over months, avoiding a clean casus belli.
The 2016 ruling speaks to borders and economic zones. It has absolutely nothing to say about a coast guard cutter cutting off a rubber dinghy. The West brought a legal brief to a knife fight.
The Danger of the Current Trajectory
By continuing to insist that the Arbitral Award is the cornerstone of regional stability, the international community is blinding itself to the next phase of the conflict.
The downside of my contrarian view is stark: admitting the ruling is ineffective means admitting that international legal structures cannot solve great power competition. It forces us to confront a far more dangerous, expensive, and volatile reality. It means acknowledging that the only thing that stops a hull is another hull.
If the Philippines and its allies continue to rely on the ghost of 2016, they will keep losing ground while winning arguments. Manila has shown incredible bravery in exposing Chinese actions to the world through their transparency campaign, but exposure without enforcement just proves to the world that Beijing can act with impunity.
Stop celebrating the anniversary of a document that changed nothing on the water. Stop collecting signatures from countries that will never send a warship to the Luzon Strait.
The 2016 Arbitral Award is not a living document; it is a monument to a geopolitical era that no longer exists. If the West wants to contest the South China Sea, it needs to stop hiding behind judges and start building the industrial, naval, and logistical capacity to match Beijing's physical presence. Anything less is just noise.
