South China Sea: The Philippines marks nine years since an international tribunal ruled against China’s territorial claims.

South China Sea Dispute and Its Historical Context
The South China Sea dispute remains a critical issue in Southeast Asia, shaping geopolitics and international relations in the region. On this day nine years ago, the Permanent Court of Arbitration in The Hague delivered a landmark decision, rejecting China’s expansive territorial claims in the South China Sea. This decision upheld the Philippine territorial rights defined under the United Nations Convention on the Law of the Sea (UNCLOS). The ruling recognized that China’s historical claims, represented by the so-called “Nine-Dash Line,” lacked valid legal basis. It was hailed as a diplomatic triumph by the Philippines and many other nations advocating for a rules-based international order in maritime domains.
Nine Years Later: The Commemoration in Manila
Manila celebrated the 9th anniversary of the tribunal decision with great emphasis, showcasing solidarity among nations advocating for fair maritime governance. Ambassadors from at least 11 countries, including significant allies like Japan and the US, attended an event to reaffirm their commitment to regional stability and the rules-based order. The Philippines’ foreign secretary, Maria Theresa Lazaro, expressed continued concerns about China’s aggressive and coercive tactics, including its disregard for the tribunal’s ruling. Lazaro highlighted that China’s persistent defiance threatens not just the Philippines’ rights but also the broader regional peace and prosperity that nations are striving to secure.
China’s Response and Continued Assertions
Since the 2016 ruling, China has refused to acknowledge the decision, often escalating tensions in the disputed waters through unilateral actions. Last year, Beijing revised its territorial baselines, a move interpreted as an effort to strengthen its de facto control over the South China Sea. Such measures, including military exercises and island-building, have drawn criticism from numerous nations. Despite international calls for resolution through diplomatic and legal mechanisms, China remains steadfast in its claims, intensifying the geopolitical complexities of the region.
Global Implications of the South China Sea Dispute
The South China Sea is among the world’s most strategic and economically vital waterways. It is not only a critical region for global maritime trade but also a nexus of natural resources, including fisheries and potential undersea energy reserves. Thus, the dispute resonates far beyond Southeast Asia, affecting international trade and ecological sustainability. China’s aggressive measures undermine global efforts to maintain a peaceful settlement process. This milestone anniversary serves as a reminder of the importance of upholding international law to ensure stability and cooperation in contested areas worldwide.
Strengthening Multilateral Ties for Resolution
Amid growing tensions, multilateral engagement remains vital. By fostering unity among nations committed to the rules-based international order, significant progress can be achieved in pressuring China to abide by legal frameworks. The attendance of ambassadors from nations like Japan and the US at the Manila commemoration underscores the international solidarity in safeguarding maritime rights. Regional alliances, robust diplomatic dialogues, and responsible enforcement of legal rulings can help pave the way toward long-term peace and equity in the South China Sea.
Commentary
Reflecting on the South China Sea Dispute and the Way Forward
The nine-year anniversary of the Hague tribunal ruling on the South China Sea is a moment not only for commemoration but also reflection. This landmark decision remains a cornerstone in the global fight for a rules-based order, particularly in contested maritime areas. The Philippines’ efforts to assert its rights, despite China’s overt defiance, highlight the resilience of smaller states in standing up against larger powers. This symbolic victory serves as a reminder of the role of international law in advocating for fairness, even when powerful nations refuse to comply.
China’s Continued Defiance and Global Reactions
China’s rejection of the tribunal’s ruling and subsequent actions in the South China Sea underscore the complexity of achieving compliance in international law. The country’s ongoing efforts to solidify its presence in the region, through both legal and assertive measures, have escalated tensions globally. It is concerning that a significant international power continues to ignore a landmark ruling, as this creates a precedent for similar disputes elsewhere. Global players, particularly the US and ASEAN countries, must intensify their diplomatic engagements and ensure China is held accountable for its actions.
Forging Partnerships to Protect Sovereignty
The attendance of various ambassadors—including representatives from Japan and the US—at Manila’s commemoration highlights the importance of partnerships in addressing global challenges. Regional and international partnerships reinforce the legitimacy of the 2016 ruling, sending a strong message of solidarity against unilateral aggression. Moving forward, fostering trust and cooperation among nations will be critical in preserving regional stability, safeguarding sovereignty, and maintaining a free and open maritime domain for all.
