Drawing on a wide body of literature on international rivalries, this comprehensive and theoretically grounded work explains the origins and evolution of the Sino-Indian rivalry. Contrary to popular belief, the authors argue that the Sino-Indian rivalry started almost immediately after the emergence of the two countries in the global arena. They demonstrate how the rivalry has systemic implications for both Asia and the global order, intertwining the positional and spatial dimensions that lie at the heart of the Sino-Indian relationship. Showing how this rivalry has evolved from the late 1940s to the present day, the essays in this collection underscore its significance for global politics and highlight how the asymmetries between India and China have the potential to escalate conflict in the future.
