This book delves into the examination of bilateral relations between India and Vietnam in the 21st century and how the Indo-Pacific as a geo-political construct lends itself to the improvement of their engagement. With the rise and increasing assertiveness of China, the slow growth of the United States, the resurgence of Japan, and the oscillating role of ASEAN as a multilateral organization, the Indo-Pacific has emerged as a theatre of international geostrategic competition. This book studies these changing geopolitical realities and new evolving strategic configurations, while addressing political, economic, defence, and strategic aspects of the relationship along with the role of China and the US in facilitating ties. India’s Act East Policy that was upgraded from the Look East Policy – one of the main drivers for India’s increasing presence in the Asia-Pacific region – is also examined in this volume. An important intervention in the study of international relations, this book will be indispensable to students and researchers of maritime studies, security studies, politics and international relations, geopolitics, and Asian studies.
