Outlook of 2026 ASEAN and Related Summits examines the opportunities and challenges facing ASEAN as the Philippines assumes the ASEAN Chairmanship in 2026. Against a backdrop of geopolitical fragmentation, energy insecurity, technological transformation, and evolving regional dynamics, this special edition of CSIS Commentaries brings together perspectives from diplomats, scholars, and policy practitioners across Southeast Asia and beyond.

Through eight contributions, the publication explores key issues shaping ASEAN’s agenda, including maritime security, digital governance, economic integration, energy resilience, trade architecture, and cultural diplomacy. 

The volume assesses how ASEAN can strengthen regional cooperation while addressing the persistent gap between institutional ambition and policy implementation.

By offering diverse and critical perspectives on the region’s future, Outlook of 2026 ASEAN and Related Summits serves as a timely resource for policymakers, researchers, and observers seeking to understand ASEAN’s priorities, challenges, and prospects at a pivotal moment for the regional organization.
