ASEAN’s New Course: How the Philippines’ Chairmanship Will Navigate the South China Sea and Beyond
Imagine a chessboard where every piece represents a nation, and the stakes are control of vital shipping lanes and resources. That’s the reality facing the Association of Southeast Asian Nations (ASEAN) as the Philippines assumes the chairmanship in 2026. With President Ferdinand Marcos Jr. signaling a firmer stance on the South China Sea, the region is bracing for a potentially pivotal shift in how ASEAN addresses its most pressing security challenge.
The Philippines Takes the Helm: A Sharper Focus on Maritime Disputes
The ceremonial transfer of the ASEAN gavel from Malaysia’s Anwar Ibrahim to President Marcos on October 28, 2025, wasn’t just a symbolic gesture. It represented a clear signal of intent. Marcos’s declaration that “cooperation cannot exist alongside coercion” is a direct message to Beijing, amidst escalating maritime confrontations. For years, ASEAN has walked a tightrope, balancing economic ties with China against the need to uphold international law and the rights of its member states. The Philippines, however, appears ready to lean more decisively towards the latter.
This shift is particularly significant given the long-delayed progress on a Code of Conduct in the South China Sea. While negotiations have been ongoing for two decades, a binding agreement remains elusive. Manila’s leadership offers a renewed opportunity to push for a meaningful code, one that prioritizes maritime safety, protects fishing rights, and establishes mechanisms to prevent escalation.
ASEAN chairmanship is a critical role, demanding diplomatic finesse and a clear vision. The Philippines’ previous stint in 2017 lacked the geopolitical urgency of the current situation. Now, expectations are considerably higher.
Beyond the South China Sea: Balancing Priorities and Regional Stability
However, the South China Sea isn’t the only challenge facing ASEAN. President Marcos has pledged to balance this focus with other crucial priorities, notably the ongoing crisis in Myanmar and the need for continued economic cooperation. This balancing act will be crucial to maintaining ASEAN’s unity and relevance.
“Did you know?”: ASEAN’s principle of non-interference has often been criticized for hindering its ability to effectively address internal conflicts within member states, like the situation in Myanmar.
Myanmar’s Crisis: A Test of ASEAN’s Resolve
The situation in Myanmar remains a complex and sensitive issue. ASEAN’s Five-Point Consensus, agreed upon in 2021, has yielded limited results. The Philippines will likely face pressure to take a more assertive role in pushing for a peaceful resolution, but navigating the sensitivities of the Myanmar junta and its regional allies will be a delicate undertaking.
Economic Cooperation: Sustaining Growth Amid Global Uncertainty
Despite geopolitical tensions, economic cooperation remains a cornerstone of ASEAN’s agenda. The bloc aims to foster regional trade, investment, and connectivity. The Philippines will need to champion initiatives that promote sustainable economic growth and address the challenges posed by global economic headwinds.
The Limits of a Pact with China: A Realistic Assessment
While a Code of Conduct offers a potential pathway to de-escalation, analysts caution that any agreement with China may lack real enforcement mechanisms. Beijing’s expansive claims in the South China Sea, based on the controversial “nine-dash line,” continue to be a major obstacle. A pact that doesn’t adequately address these claims risks being largely symbolic.
“Expert Insight:” Dr. Renato de Castro, a professor of International Studies at De La Salle University in Manila, notes, “The Philippines’ chairmanship presents an opportunity to strengthen ASEAN’s collective bargaining power with China, but success hinges on maintaining a united front among all member states.”
The key will be to focus on practical measures that build trust and reduce the risk of accidental clashes, such as joint maritime exercises and hotlines for communication. However, a comprehensive resolution to the South China Sea dispute remains a long-term challenge.
Navigating Our Future Together: The Philippines’ Guiding Principles
The Philippines’ theme for its ASEAN chairmanship, “Navigating Our Future Together,” encapsulates its vision for the bloc. President Marcos has emphasized peace, prosperity, and people empowerment as guiding principles. This suggests a focus on inclusive growth, sustainable development, and strengthening regional connectivity.
“Pro Tip:” Businesses operating in Southeast Asia should closely monitor developments related to the South China Sea and the Code of Conduct negotiations. Potential disruptions to shipping lanes and resource access could have significant economic implications.

- Increased Geopolitical Competition: The rivalry between the United States and China will continue to intensify in the region, putting pressure on ASEAN to maintain its neutrality.
- Digital Transformation: The rapid pace of digital transformation will create new opportunities and challenges for ASEAN economies.
- Climate Change: Southeast Asia is particularly vulnerable to the impacts of climate change, requiring urgent action to mitigate risks and build resilience.
- Regional Economic Integration: The Regional Comprehensive Economic Partnership (RCEP) will continue to drive economic integration within the region.
