The Association of Southeast Asian Nations (ASEAN) and India are bound together by their shared history and culture. Relation with ASEAN is one of the cornerstones of India's Foreign Policy. Starting in 1992, when India joined ASEAN as a sectoral dialogue partner, ASEAN and India are going to complete thirty years of their bilateral relations in 2022. The ongoing pandemic has imposed many global and regional challenges. Moving from cooperation to integration, there is a need to jointly address challenges to strengthening the partnership between ASEAN and India in various areas. This book addresses some of these challenges in a lucid manner. It presents a set of 15 research papers, which were presented at the sixth ASEAN-India Network of Think-Tanks (AINTT) roundtable in 2020. Divided in five major sections, this volume reviews some of the achievements of ASEAN-India relations while completing three decades of partnership, and presents a set of new agenda for the fourth decade. It also underlines the desire of the ASEAN countries and India to diversify and further strengthen the relations in the third decade. This volume is also published to commemorate the thirty years of ASEAN-India relations.
