The Lahore treaty was one of the most important and historical treaties of India and Pakistan to normalise the relations to ease up the military tensions in South Asia. In 1972, the Shimla Treaty was acceded to establish peaceful relations in the aftermath of the war in 1971 and committed both nations to resolving bilateral disputes by peaceful dialogue and co-operation. In 1978, Pakistan made a proposal to limit the nuclear race between two countries and to establish South Asia Nuclear Weapon Free Zone (SANWFZ), for which negotiations were never concluded.
