On a more direct geopolitical level, India`s greatest asset was the transformation of the 1949 UN-approved ceasefire line in Kashmir into a hardened line of control (LoC), based on the new ceasefire position of 17 December 1971. It is politically and symbolically that Indian politicians have been able to claim some success. The Shimla agreement was an expression of the Indian framework for the security of South Asia, namely the standard of bilateralism. Since India`s fatal decision in 1948 to seek third-party mediation in the India-Pakistan conflict, policymakers have struggled to limit interference by outsiders in the Kashmir conflict. The interventions of Krishna Menon of the United Nations in 1957 were the first diplomatic declarations to unravel India from the participation of third parties. In 1965, the standard of bilateralism had been insinuated, albeit ironically, to a third place in Tashkent, as part of the proactive diplomatic efforts of the Soviet Union. In 1972, Indian politicians explicitly enshrined this principle in Shimla. The actual negotiations began on 28 June 1972 and lasted five days, with India clinging to the approach of Dhar, in which the return of prisoners of war and Indian-occupied territory was part of a set of permanent agreements on the formal delimitation of the Kashmir border. At the inaugural session on 28 June, Mr Dhar made it clear that the conclusion of a peace settlement was an « essential » condition for the repatriation of prisoners of war. On June 29, he sought a clear framework.
Any « consensual wording » should be consistent with the current situation and « capable of implementing. » Dhar stressed that « the world is moving quickly towards bilateralism. » Mr. Ahmed, however, offered minimal commitments and sought to maintain the old UN-centred conflict resolution framework. Haksar also stressed that India and Pakistan should « solve our own problems » without « including distant countries in our disputes. » On 30 June, Dhar suffered a mild heart attack, with Haksar taking the lead for the rest of the summit. However, India`s momentum in the negotiations remained consistent. 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.  Simla Agreement on Bilateral Relations between India and Pakistan, signed by Prime Minister Indira Gandhi and Pakistani President Z.A. Bhutto, on 2 July 1972 in Simla. The two ministers invoked the 1972 Shimla Agreement and said that bilateral issues could only be resolved with his help — and nothing else.
The agreement is the result of the two countries` determination to « end the conflict and confrontation that have so far weighed on their relations. » He designed the steps to be taken to further normalize mutual relations and also defined the principles that should govern their future relations.    According to historian Ramachandra Guha, India wanted a « comprehensive treaty to solve all outstanding problems, » while Pakistan preferred a « piecemeal approach. » Although India wanted a treaty, it reached an agreement because of the bitter negotiations of the Pakistanis. 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. 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.
