This agreement, commonly known as the Simla Pact, was born out of the 1971 war between the two countries over developments in the eastern wing of Pakistan. The aim of the agreement was to define the principles that should govern their future relations. It also provided for measures to be taken to further normalize bilateral relations. Most importantly, it forced the two countries to “resolve their differences through bilateral negotiations by peaceful means.” This agreement is ratified by both countries in accordance with their respective constitutional procedures and enters into force from the date of exchange of ratification instruments.  The agreement was agreed upon and was signed after the Indo Pak War of 1971, after which East Pakistan was liberated, which led to the creation of Bangladesh. In this context, delegations from both countries will meet from time to time to develop the necessary details. (iii) Withdrawals will begin on the effective date of this agreement and will be concluded within 30 days.  As part of this agreement, the two nations, India and Pakistan, had agreed to refrain from any threat and violence, in violation of the line of control in Jammu and Kashmir. The Delhi Agreement on the Return of War and Civilian Internees is a tripartite agreement between these states, signed on 28 August 1973.
The agreement was signed by Kamal Hossain, the Foreign Minister of the Government of Bangladesh, Sardar Swaran Singh, the Indian Minister of Foreign Affairs and Aziz Ahmed, Minister of State for Defence and Foreign Affairs of the Pakistani government.    On 2 July 1972, the two countries agreed. The main clauses of the Simla agreement are: recalling its agreement of 23 September 1998, that an environment of peace and security is in the supreme national interest of both sides and that the resolution of all outstanding issues, including Jammu and Kashmir, is essential for this purpose. The summit conference between Bhutto and Indra Gandhi opened in Simla on the agreed date. The summit conference was held from June 28 to July 2, 1972. The objective of the agreement was to define the measures envisaged to normalize bilateral relations and to resolve mutual disputes through peaceful means and bilateral negotiations. India wanted to solve all the problems in one package, so it proposed a treaty of friendship that required the two countries to refrain from the use of force in dispute resolution, not to interfere in each other`s internal affairs, not to participate in the settlement of their disputes and to renounce military alliances directed against each other.
