The 2016 decision of the Permanent Court of Arbitration in The Hague did not settle the Spratly Islands dispute; instead, it ushered in a new phase marked by ongoing intimidation at sea. The tribunal ruled that China’s “nine‑dash line” lacks any legal foundation and affirmed that the Philippines alone enjoys exclusive fishing and seabed‑resource rights within 200 nautical miles of its coast. The court further identified Mischief Reef and Second Thomas Shoal as lying on the Philippine continental shelf.
Beijing dismissed the award as “a piece of waste paper,” yet dredging and other activities proceeded unabated. Rather than acquiesce, Chinese coast‑guard vessels and maritime militia groups have repeatedly confronted Philippine boats.
Incidents have been recorded almost every year since the ruling. In January 2011, Philippine observers noted three warning shots fired across the bows of Filipino fishing skiffs near Jackson Atoll. A year later, a two‑month standoff erupted when the Philippine frigate Gregorio del Pilar attempted to detain Chinese fishermen accused of poaching at Scarborough Shoal; China responded by deploying surveillance ships and sealing off the lagoon. Further confrontations followed.
In 2014, water‑cannon attacks were filmed at Panatag Shoal, and PLA troops blocked a Philippine supply vessel bound for the grounded warship Sierra Madre, which serves as Manila’s outpost on Second Thomas Shoal. Although the tactics have varied, the objective—pressuring the Philippines to relinquish its asserted rights—remains constant.
On 25 September 2019, Philippine Foreign Secretary Teodoro Locsin Jr. addressed the United Nations General Assembly, stating unequivocally that “the award is non‑negotiable; no state, however powerful, can unilaterally overturn it.” His remarks reinforced a line drawn by the tribunal, but the enforcement gap persists. Legally, the ruling is final and binding. Judges appointed under the United Nations Convention on the Law of the Sea concluded that China never possessed historic title to the waters inside the dashed line.
Practically, however, the award has not translated into control on the ground—or rather, on the water. China continues to treat the contested zones as its own, while the Philippines holds only the legal claim.
For Filipino fishers, the situation is immediate and personal. Their skiffs regularly encounter Chinese cutters, jeopardizing livelihoods that the tribunal has affirmed belong to the Philippines. For Manila’s government, the challenge lies in enforcing a decision that the world’s largest military power refuses to acknowledge.
The broader regional implication is equally stark: if a binding arbitration award can be ignored without repercussions, the rules‑based order that underpins maritime stability in the South China Sea risks erosion. To date, the 2016 award remains on the books—unchanged, unrenegotiated, and unoverturned.
What has changed is the pattern of defiance that followed. The legal case is closed; the confrontation at sea continues.
