ACMECS and its latest development

Since 2003, ACMECS has empowered Mekong countries to lead their own path to regional growth. With new milestones like the Interim Secretariat, expanded Development Partners, and a dedicated Development Fund, ACMECS is entering a new era—turning vision into action for a more connected and sustainable Mekong subregion.

10th ACMECS Summit – The Journey in Action

The 10th ACMECS Summit, held in Kunming, China, marked major milestones in Mekong sub-regional cooperation — from launching the official ACMECS website to welcoming New Zealand as a new development partner and advancing water resource management.

ACMECS & Development Partners (DPs)

Established in 2003, the Ayeyawady-Chao Phraya-Mekong Economic Cooperation Strategy (ACMECS) unites five member countries—Myanmar, Lao PDR, Cambodia, Thailand, and Viet Nam—to bridge development gaps and support ASEAN integration. Guided by the ACMECS Master Plan, its focus lies on three pillars: Seamless Connectivity, Synchronized Economics, and Smart, Sustainable Growth.

ACMECS collaborates with Development Partners, including Australia, China, India, Japan, the Republic of Korea, the United States, and New Zealand, to implement prioritized projects, connect regional frameworks, and support sustainable growth. Together, they are shaping a brighter, more connected future for the Mekong subregion.
