Philippines Navigates ASEAN Chairmanship Amidst Regional Tensions and Domestic Political Shifts

As the Philippines assumed the chairmanship of the Association of Southeast Asian Nations (ASEAN) on January 1, 2026, under the theme “Navigating Our Future, Together,” it inherited a complex geopolitical landscape. The organization faces ongoing crises in Myanmar, persistent tensions in the South China Sea (SCS) and a challenging international environment marked by geoeconomic competition and the second administration of Donald Trump. The first quarter of the Philippines’ leadership has focused on continuity and managing existing challenges, while domestic political factors add another layer of complexity.

Maintaining Continuity on Key Issues

Early engagements, such as the ASEAN Foreign Ministers’ Retreat in Cebu in late January, demonstrated the Philippines’ commitment to established ASEAN positions. A central focus has been Myanmar, where Manila reiterated support for the Five-Point Consensus and restricted high-level representation from the military authorities. Foreign Secretary Maria Theresa P. Lazaro’s visit to Myanmar on January 6, 2026, signaled ASEAN’s non-recognition of the recent electoral process, emphasizing the need for inclusive dialogue and an end to violence. This approach, while criticized by some, reflects ASEAN’s long-standing practice of engagement without endorsement.

Balancing Act in the South China Sea

The Philippines, as a claimant state in the South China Sea, faces a delicate balancing act. While asserting its maritime rights under the United Nations Convention on the Law of the Sea (UNCLOS 1982), Manila must also maintain regional cohesion and progress negotiations with China on a Code of Conduct (CoC). Foreign Secretary Lazaro has consistently emphasized the importance of a CoC consistent with UNCLOS, signaling a continued commitment to a rules-based approach. However, expectations for a legally binding conclusion within 2026 remain tempered by divergent strategic calculations among ASEAN member states and the pace of negotiations with China.

Addressing Regional Conflicts and Integration

Beyond Myanmar and the SCS, the Philippines is also addressing other regional issues, such as tensions on the Cambodia–Thailand border. The chairmanship has supported existing ASEAN mechanisms for ceasefire verification and de-escalation, prioritizing the prevention of bilateral frictions from escalating into broader regional fragmentation.

Simultaneously, the Philippines is continuing work on ASEAN’s long-term integration agenda, progressing with sectoral and ministerial meetings in areas like economic cooperation, tourism, and energy. These efforts are linked to the implementation of the ASEAN Community Vision 2045, focusing on peace, security, prosperity, and people-centered empowerment.

Domestic Political Challenges

The success of the Philippine chairmanship is not solely dependent on regional diplomacy. Domestic political dynamics pose significant challenges. President Ferdinand Marcos Jr.’s approval ratings have declined since 2022, impacted by the dissolution of his alliance with the Duterte family and ongoing corruption investigations. The potential impeachment trial of Vice President Sara Duterte and the ongoing International Criminal Court investigation into former President Rodrigo Duterte further complicate the political landscape.

Sara Duterte’s announcement of her candidacy for the 2028 presidential election has created a formidable opposition force, potentially challenging the Marcos Jr. Administration’s foreign policy goals, including its approach to the South China Sea. Recent diplomatic tensions with China, stemming from a coast guard official’s caricature of Xi Jinping, were de-escalated by the Department of Foreign Affairs to avoid jeopardizing the Philippines’ role as ASEAN chair. However, concerns remain that such actions could be interpreted as a shift in the country’s commitment to its maritime interests.

Looking Ahead

The first quarter of the Philippine chairmanship underscores a key reality for ASEAN in 2026: preserving cohesion amidst mounting challenges is paramount. Manila’s approach has been measured and calibrated. The country’s ability to project stability, bureaucratic coherence, and policy consistency will be crucial in inspiring confidence among its regional and international counterparts. the success of the Philippines’ chairmanship will depend on its capacity to navigate both regional complexities and domestic political headwinds.
