ACMECS Interim Secretariat (AIS)




The Ayeyawady – Chao Phraya – Mekong Economic Cooperation Strategy (ACMECS) is a sub- regional cooperation framework initiated by Thailand in 2003, with a view to enhancing development and connectivity of the Mekong subregion in all dimensions. It is composed of Cambodia, Lao PDR, Myanmar, Thailand and Viet Nam as members. ACMECS acts as the “core of the core” to align strategic interests of the subregion’s architecture with Mekong-led development agendas in setting direction for cooperation. While the meetings at senior official and working levels are held on a regular basis, the ACMECS Summit is convened every two years. At present, the Lao PDR is the current Chair of ACMECS, and Thailand has long been tasked as the ACMECS coordinator for Development Partners.

As the member countries’ priorities evolved against a competitive globalized order, ACMECS’s regional agenda was realigned to strategically optimize its strategic location, abundant natural resources, and diverse populace to set the progression for the subregion to become a powerhouse marked by robust trade and investment, linked transport and digital networks, an equipped population, technological innovation, and environmental sustainability.

Cognizant that these can only be realized and sustained in mutual cooperation, ACMECS has been expanding partnerships with other countries within and beyond Asia. It has also been forging deeper engagement with a broader range of public-private stakeholders to pool resources and efforts in creating an enabling and balanced socioeconomic environment, particularly in responding to the impacts of the pandemic and deploying longer-term post-recovery strategies.

Concomitantly, ACMECS has also been solidifying its value-added role in aligning complementarities by building upon gains of existing regional cooperation strategies and national development programs to address common interests, invest in shared progress, and deepen solidarity—understanding that inclusive alliances will propel sustainable economic growth, not only in Mekong and ASEAN countries but across the continent.

About ACMECS Interim Secretariat (AIS)

Against this backdrop, ACMECS leaders have agreed to escalate its commitments by forming a mechanism for efficient coordination between member countries, project implementation and engagement with development partners as well as external partners, institutions and think tanks. At the 9th ACMECS Summit, the Meeting agreed to the establishment of an ACMECS secretariat which shall be located in the Mekong Cooperation Unit (MCU), Ministry of Foreign Affairs of Thailand.

To support the AIS in its initial 3-year set-up, the Mekong Institute (MI) has been appointed as a back-office to MCU/AIS providing technical support. To solidify this partnership, an MOU/Agreement between ACMECS (represented by Thailand) and the MI is scheduled to take place on February 2, 2024.
