This book investigates India-ASEAN partnership and their overlapping perspective on the Indo-Pacific region and big powers' contestation and competition in this region providing specific nuances and newer insights. It is policy-oriented and examines the confluence of ASEAN’s Outlook for Indo-Pacific (AOIP) and India’s Indo-Pacific Oceans Initiative (IPOI). It brings out various contemporary geopolitical drivers that highlight the hidden complementarities and gaps in India-ASEAN multi-sectoral connectivity and its future. The book provides a balanced assessment of evolving trends, undergirded by theoretical debates and empirical analyses with diverse sub-regional and country perspectives of the intersection between the potential for regional convergence, domestic capacity issues, and security interests. It is thus of immense use for thinktanks and media commentators, policy makers, and researchers of Indo-Pacific & Asian affairs, international relations, and China-US relations, interested in evolving contours of Indo-Pacific geopolitics.
