The agreement was a peace treaty signed by the two nations after the end of the Bangladesh War in 1971. Bangladesh had been part of Pakistan since partition in 1947. In 1971, it waged a war of independence against Pakistan. India entered the war as an ally of Bangladesh, which turned the war into an Indo-Pakistan war in 1971. The agreement was ratified the same year by the parliaments of both countries. 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.  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. 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.
In 1998, the foreign ministries of both countries launched a peace process to ease tensions in the region. On 23 September 1998, the two governments signed an agreement on the recognition of the principle of the establishment of an environment of peace and security and the resolution of all bilateral conflicts, which became the basis of the Lahore Declaration.  On 11 February 1999, the Pakistani Ministry of Foreign Affairs announced the official visit of Indian Prime Minister Atal Bihari Vajpayee on the first bus link between the two countries. In 2001, Pakistani President Pervez Musharraf visited India on 14 and 16 July for a historic two-day summit. However, the talks failed and no text of agreement could be found. At the end of the historic summit, India and Pakistan signed the Lahore Declaration, a bilateral agreement and a governance treaty that was to be ratified by the parliaments of both countries in the same year. As mentioned 27 years earlier in the Simla Agreement, the Lahore Declaration notably confirmed the need to resolve the Kashmir issue bilaterally.
