On July 2, 1972, the two countries reached an agreement. The main elements of the Simla Agreement are: the Delhi Agreement on the Repatriation of War and Civil Interior 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.    The summit conference between Bhutto and Indra Gandhi opened in Simla on the decided 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. Pakistan wanted to focus on issues as immediate as the release of prisoners of war, the withdrawal of troops and the resumption of diplomatic relations. It rejected the Indian proposal on the grounds that it would imply a lasting adoption of the partition of Kashmir and the withdrawal of the UN Kashmir dispute.
In the hope of saving an agreement, Bhutto called Gandhi directly. During the climate meeting, Gandhi stressed the main advantage of the Indian proposal in Kashmir – neither side was forced to physically abandon the territory or exchange populations. With “obvious feeling and sincerity,” Bhutto acknowledged that India`s proposal was the only possible one, but that a legally binding commitment would significantly weaken its domestic political position and strengthen the military establishment. He could give nothing but oral assurance that the de facto border in Kashmir, in Bhutto`s words, would gradually acquire the “characteristics of an international border.” On the other hand, India`s concession was concrete and in advance. India abandoned its “package arrangement by agreeing to withdraw troops from the international border before concluding an agreement on Kashmir.”
