The Indo-Pacific has emerged as the defining theatre of 21st-century geopolitics where competing visions of order, security and connectivity intersect in the vast maritime realm. Organised into four thematic sections- Indo-Pacific Setting, Policies, Strategies and Action this edited volume brings together diverse scholarly perspectives that examine the conceptual foundation of the Indo- Pacific. The chapters explore themes ranging from geopolitical narratives and ASEAN centrality to climate governance, the role of media in the Indo-Pacific, non-traditional security threats, India’s institutional balancing and its role in the multipolar world, the strategic significance of QUAD, and the growth of submarines' roles in the region. This book provides a timely and nuanced contribution to the growing body of literature on the Indo-Pacific by offering a comprehensive understanding of diplomacy, security, governance, naval power and India’s expanding role in the Indo-Pacific region.
