A coalition of 14 nations, including the US and UK, has reiterated the illegality of China's claims in the South China Sea, based on a 2016 arbitration ruling.
Washington DC, United States Jul 13, 2026 ALN: MANILA, Philippines — The United States, the United Kingdom, and a dozen other Western and Asian countries reasserted on Sunday that China’s expansive claims in the South China Sea are illegal based on a 2016 arbitration ruling. This reaffirmation comes amidst ongoing tensions in the region, where territorial disputes have implications not only for the countries directly involved but also for global trade and international relations.
A joint statement issued by the 14 nations said they rejected “destabilizing” actions in the disputed waters that threaten regional stability. The 27-nation European Union released a separate statement, reaffirming the ruling as a “landmark decision in the peaceful settlement of disputes.” The emphasis on peaceful resolution reflects a broader international consensus on the importance of adhering to established legal frameworks in resolving maritime disputes.
The statements commemorated a July 12, 2016, arbitration ruling by a tribunal established in The Hague under the United Nations Convention on the Law of the Sea (UNCLOS), which stated that the landmark decision is “final and legally binding.” The tribunal determined that China’s claims to historical rights over the South China Sea were not supported by international law, a significant ruling that has been a point of contention between China and the Philippines, as well as other Southeast Asian nations.
China reiterated Sunday that the ruling was “null and void and has no binding force” and that Beijing “neither accepts nor recognizes it.” This dismissal of the ruling is consistent with China's longstanding position, which asserts its sovereignty over the majority of the South China Sea, despite international legal challenges. The Chinese government has emphasized its historical claims, arguing that its rights in the region are rooted in centuries of maritime activity.
China refused to join the arbitration initiated by the Philippines in 2013 after a tense standoff in the contested waters a year earlier that ended with Beijing effectively seizing a disputed shoal. This incident was a pivotal moment in the South China Sea dispute, highlighting the aggressive tactics employed by China to assert its claims. The refusal to participate in the arbitration process has been criticized by many countries, which view it as a rejection of international norms and legal processes.
Beijing rejected the 2016 ruling and continues to defend its claims to virtually the entire sea passage, a key global trade route that has long been feared as one of Asia’s most active flashpoints. The area has been the scene of repeated territorial standoffs involving China and the Philippines, Vietnam, Malaysia, Brunei, and Taiwan. These confrontations have raised concerns about potential military conflicts, given the strategic importance of the South China Sea for international shipping and regional security.
“We reaffirm the Arbitral Tribunal’s decision that there is no legal basis for China’s expansive maritime claims in the South China Sea, including those based on 'historic rights,'” the U.S.-led statement said. This assertion underscores the commitment of the involved nations to uphold international law and the principles of freedom of navigation and overflight in the region.
The arbitration tribunal largely decided in favor of the Philippines, ruling that under UNCLOS, “there was no legal basis for China to claim historic rights to resources” in the South China Sea outside of its regular territorial areas recognized under the convention. This ruling has provided a legal framework for the Philippines and other claimant states to challenge Chinese assertions of sovereignty over vast maritime areas.
UNCLOS, largely regarded as the treaty governing the world’s oceans and seas, took effect in 1994 and has been ratified by more than 170 countries and parties, including China and the Philippines. However, China's non-compliance with the ruling raises questions about the effectiveness of international legal mechanisms in resolving disputes involving powerful nations.
In addition to the U.S. and Britain, the other countries listed in Sunday’s statement were the Philippines, Japan, Australia, New Zealand, Canada, Germany, Italy, Estonia, Latvia, Lithuania, Romania, and Slovenia. This coalition reflects a growing concern among nations about China's increasing assertiveness in the South China Sea and the potential implications for regional security and international trade.
“We reiterate our strong opposition to any destabilizing or unilateral actions including by force or coercion that threaten peace and stability in the region,” they said. This statement indicates a unified front against aggressive tactics that could escalate tensions in the area. The emphasis on multilateral cooperation to address these challenges is vital for maintaining stability in the region.
The nations stressed “our strong opposition to the use of coast guard, military, and maritime militia forces to harass, obstruct, intimidate lawful operations by other states at sea or in the air and in so doing endanger the safety of personnel and fishermen and seriously degrade regional peace and security.” Such actions have been reported frequently, with numerous incidents involving Chinese vessels confronting those of other nations, leading to dangerous encounters at sea.
“Freedom of navigation and overflight as well as other internationally lawful uses of the sea as reflected in UNCLOS” must be upheld, the countries said, adding that the territorial disputes should be resolved peacefully based on the 1982 U.N. convention. This insistence on upholding international norms is crucial for ensuring that maritime routes remain open and accessible to all nations, which is particularly important given the strategic significance of the South China Sea for global commerce.
In Beijing, China’s Ministry of Foreign Affairs said the arbitration tribunal and its ruling “seriously contravene the general practice of international arbitration” and “gravely infringe upon China’s legitimate rights as a sovereign state and state party to UNCLOS and are unjust and unlawful.” This response reflects China's broader narrative of victimization and resistance against what it perceives as Western encroachment on its sovereignty.
“China opposes and will never accept any claim or action based on those awards,” the Chinese foreign ministry said, adding that Beijing “does not accept any means of third-party dispute settlement or any solution imposed on China.” This rejection of third-party arbitration highlights the complexities of international law when dealing with powerful nations that prioritize national sovereignty over compliance with international rulings.
Territorial confrontations in the disputed waters have become more prevalent in recent years, particularly between Chinese and Philippine and Vietnamese forces and fishing fleets. These encounters have led to an increase in military presence in the region, with various nations conducting freedom of navigation operations to challenge China's claims.
Chinese coast guard ships and support vessels have used powerful water cannons, military-grade lasers, and dangerous blocking maneuvers against Philippine forces and fishermen from rival claimant countries that have led to collisions in the high seas and high-risk encounters in the air. Such aggressive tactics not only threaten the safety of personnel but also contribute to rising tensions and the potential for conflict in an already volatile region.
The United States has repeatedly called on China to comply with the arbitration ruling. The U.S. has positioned itself as a key ally to the Philippines and other nations in the region, emphasizing the importance of upholding international law and ensuring that maritime disputes are resolved through peaceful means.
The former Biden and current Trump administrations both warned that Washington is obligated to defend the Philippines, its oldest treaty ally in Asia, if Filipino forces, vessels, or aircraft come under armed attack in the disputed waters. This commitment reflects the strategic importance of the Philippines in U.S. foreign policy, particularly in the context of countering Chinese influence in the Indo-Pacific region.
As the situation in the South China Sea continues to evolve, the reaffirmation of the 2016 arbitration ruling by the U.S. and its allies serves as a reminder of the ongoing challenges in balancing national interests, regional stability, and adherence to international law. The implications of these disputes extend beyond the immediate region, affecting global trade routes and international relations, making it imperative for the international community to remain engaged in seeking a peaceful resolution to these complex issues.
