Launched in Vientiane, Lao PDR in 2000, the Mekong-Ganga Cooperation (MGC) completed twenty years in 2020. The MGC initiative is a sub-regional cooperation organisation comprising India and five ASEAN countries, namely, Cambodia, Lao PDR, Myanmar, Thailand and Vietnam. To commemorate the 20 years of establishment of MGC, the Indian Council of World Affairs (ICWA) in collaboration with the ASEAN-India Centre (AIC) at Research and Information System for Developing Countries (RIS) organised an international conference entitled Twenty Years of Mekong-Ganga Cooperation (MGC) on 5-6 November 2020 at New Delhi in virtual mode. This volume is an outcome of the aforesaid conference, and examines the connected past, present, and future of MGC. This commemorative volume presents a selected set of papers, which were presented at the aforesaid conference. Although the economic engagements between India and Mekong have been limited, there is further scope to scale up our economic relations. This volume shows the path to strengthen the MGC partnership in the third decade of its establishment. This book will serve as a valuable resource for policymakers, research scholars, practitioners and regional cooperation specialists.
