This book assesses the evolving competition between two Asian powers, India and China, for primacy in the South Asian region. By collating voices from the region, it explores how the competition is playing out and shaping the regional order and how South Asian states are responding to the increasing competition. The volume highlights how South Asian countries have leveraged their agency and exploited the competition to further their interests in multiple ways. By focusing on these objectives, this book reflects on key themes and concepts in the discipline of International Relations, such as great power competition, security dilemma, and agency-seeking behaviour of smaller countries. Part of the International Politics in the Age of Disruption series, this book will be indispensable for students, researchers, and practitioners of military studies, security studies, hierarchy of power, political studies, international relations, and South Asian studies.
