Trace the evolution of India-China diplomatic relations from the 1962 conflict to the present, using instances of cooperation despite rivalry.

India was the first non-socialist bloc country to establish diplomatic relations with the People's Republic of China on 1 April 1950, and the 1962 border conflict was a setback to those ties [1]. The trajectory since has been one of managed rivalry punctuated by genuine cooperation.

Estrangement to thaw (1962-1988)

• The conflict froze contact; Ambassador-level representation was restored only in 1976, ending fourteen years of downgraded ties [4].
• Even before full normalisation, China joined the Asian Group consensus backing India's candidature for a non-permanent UNSC seat vacated by Japan; India served the 1977-78 term [4][3].
• PM Rajiv Gandhi's 1988 visit "marked a beginning in the improvement of bilateral relations" [1].

Institutionalising peace (1993-2013)

• Peace and Tranquillity Agreement (1993) and the Confidence Building Measures Agreement (1996) committed both sides to respect the LAC pending settlement [2].
• Vajpayee's 2003 visit produced the Declaration on Principles and the Special Representatives mechanism on the boundary question — 24 rounds held so far [1].
• Functional cooperation deepened: the 2005 Strategic and Cooperative Partnership, the 2006 Expert-Level Mechanism on trans-border rivers, and the 2012 WMCC on border affairs [1][2].

Summitry amid friction (2014-2020)

• Informal summits at Wuhan (2018) and Chennai (2019), alongside sustained engagement at BRICS, SCO and G20 [1].
• April-May 2020 incidents in Eastern Ladakh adversely impacted relations, exposing the limits of dialogue [1].

Cautious normalisation (2024-present)

• A patrolling agreement (October 2024) enabled disengagement from all 2020 friction points, followed by leader-level talks at Kazan [1].
• The Prime Minister's China visit (31 August 2025), resumption of the Kailash Mansarovar Yatra and direct flights, and the 35th WMCC meeting signal calibrated re-engagement [1].

Thus, competition over the boundary and regional influence has coexisted with pragmatic cooperation in multilateral forums, river data-sharing and pilgrimage. Sustained adherence to existing border mechanisms, backed by the Panchsheel principles of mutual respect and peaceful coexistence, offers the surest path from disengagement to durable de-escalation.
