General Information about the GMS Program
The Greater Mekong Subregion Economic Cooperation Program (GMS Program) is a cooperation framework among 6 countries in the Mekong River Basin, including Cambodia, Lao PDR, China (Yunnan Province and Guangxi Zhuang Autonomous Region), Myanmar, Thailand, and Vietnam. It was initiated in 1992 through the efforts of these 6 countries and with support from the Asian Development Bank (ADB) to promote economic, social, and environmental cooperation based on the comparative advantages of each country. Currently, the GMS Program operates under the GMS Economic Cooperation Program Strategic Framework 2030, which aims to develop the Greater Mekong Subregion into an integrated, prosperous, sustainable, and inclusive subregion.
The implementation of the GMS Program throughout its history has been based on 3 pillars of development, or the 3Cs principle, consisting of:

Connectivity
Focusing on sustainable physical infrastructure development and upgrading transportation networks to become economic corridors

Competitiveness
Facilitating cross-border movement of people and goods, developing production chains, agriculture, tourism, and urban development

Community
Building a community with a shared future by promoting cross-border cooperation in public health and the environment, as well as improving the well-being of the people.
The GMS Program emphasizes the concept of developing Economic Corridors, which involves connecting cross-border economic areas through infrastructure, policy coordination, and harmonization of regulations. This aims to promote economic activities and the movement of goods, services, people, and capital in the Greater Mekong Subregion. There are 3 main economic corridors:
(1) North-South Economic Corridor (NSEC) is the main route connecting southern China and Lao PDR to access the sea.
(2) East-West Economic Corridor (EWEC) is a route connecting major economic cities between Vietnam, Lao PDR, Thailand, and Myanmar, covering a total distance of 1,500 kilometers.
(3) Southern Economic Corridor (SEC) is a route connecting major economic cities between Thailand-Cambodia-Vietnam, including Myanmar, and Vietnam-Cambodia and Laos.
