India and China: Conflict, cooperation, and the future prospects of strategic alignment

India and China, two major Asian powers with deep civilizational legacies and expanding global influence, share a relationship characterized by strategic ambivalence. Since India’s early recognition of the People’s Republic of China (PRC) in 1949 and the articulation of the Panchsheel principles in 1954, bilateral engagement has oscillated between normative cooperation and geopolitical rivalry. This article provides a comprehensive historical and theoretical analysis of Sino-Indian relations. Integrating Realism, Constructivism, and Power Transition Theory, the paper examines the transformation from post-colonial solidarity to military confrontation in 1962, subsequent institutionalized conflict management, growing economic interdependence, and contemporary strategic competition. It argues that although structural constraints make a formal alliance unlikely, issue-based cooperation within a multipolar order remains both feasible and strategically rational. The future trajectory of India–China relations will depend on effective management of the security dilemma, recalibration of regional ambitions, and institutional stabilization.
