evidence: The Panchsheel Agreement was signed between India and China in April 1954. Mutual respect for each other's territorial integrity and sovereignty, mutual non-aggression, mutual non-interference in each other's internal affairs, equality and mutual benefit and peaceful co-existence were the Five Principles of Peaceful Co-existence incorporated into the preamble of the 1954 India–China agreement on trade and cultural ties with Tibet. However, China started to dishonour the Treaty within a few months after the signing of the same in the form of revision of maps, territorial claim over Barahoti, intrusions in Damzan, Nilang and construction of a road to connect Sinkiang with Tibet.
