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. 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. 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.» The agreement did not prevent relations between the two countries from deteriorating until the armed conflict, the last time during the 1999 Kargil war. In Operation Meghdoot of 1984, India seized the entire inhospitable region of the Siachens Glacier, where the border was clearly not defined in the agreement (perhaps because the area was considered too arid to be controversial); This was considered by Pakistan to be a violation of the Simla agreement. Most of the subsequent deaths in the Siachen conflict were caused by natural disasters. B, like the avalanches of 2010, 2012 and 2016. (iii) Withdrawals will begin on the effective date of this agreement and will be concluded within 30 days.  In 2001, Pervez Musharraf, then President of Pakistan, visited India on 14 and 16 July for a historic two-day summit in Agra at the invitation of Prime Minister Vajpayee. However, the talks failed and no text of agreement could be found. 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. While Kashmir spoke only of «maintaining the line of control,» a clause was added to India`s insistence that the two countries would settle their differences only through «peaceful means through bilateral negotiations or other peaceful mutually agreed means,» Guha writes. This theoretically excludes third-party mediation in Kashmir. 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.  In addition to the withdrawal of troops and the return of prisoners from the 1971 war, the Simla Agreement was a model for India and Pakistan to maintain friendly and neighbourhood relations between them.
As part of the agreement, the two warring countries promised to renounce conflicts and confrontations and strive for peace, friendship and cooperation. Given the situation that required an agreement between the Indian and Pakistani leaders, Zulfikar Ali Bhutto, the Pakistani president was invited to a summit in Simla during the last week of June 1972.https://wikifama.com/simla-agreement-background/
