(iii) Withdrawals will begin on the effective date of this agreement and will be concluded within 30 days.  The agreement is the result of the determination of the two countries to “end the conflict and confrontation that have so far affected 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.   The Simla Agreement reads itself as a communiquÃ© rather than a peace agreement with a country that had waged war on India. Nothing in the agreement has put Pakistan in a state of good behaviour in the future. It also contained some ridiculous expectations, such as the clause that required both governments to “take all measures within their power to prevent hostile propaganda against each other.” While the two heads of state and government clarified the general agreement at the summit, lengthy negotiations took place over 19 meetings in nearly two months, before the details were whipped. It is said that Prime Minister Indira Gandhi intervened several times to keep the talks going, and the final draft was approved by his cabinet. The Bangladeshi government also expressed full satisfaction with the agreement and endorsed it. This is how the aforementioned agreement of August 29, 1972 was born. On 29 August 1972, the two chief negotiators, Parmeshwar Narain Haksar (India, Parmeshwar Narain Haksar) and Aziz Ahmed of Pakistan, signed the final agreement between India and Pakistan, the summit between Indian Prime Minister Indira Gandhi and Pakistani President Zulfikar Ali Bhutto. It appears that a tacit agreement on the release of Pakistani prisoners of war was reached in early 1972, since Bhutto overturned the death sentence handed down by Sheikh Mujibur Rehman on 8 January 1972. The sheikh took over as Prime Minister of Bangladesh on 10 January 1972. The United States declared Bangladesh sovereign on April 4, 1972.
This laid the groundwork for the Shimla agreement. However, Pakistan officially recognized Bangladesh on 22 February 1974 and China on 31 August 1974. As part of the agreement, the two nations, India and Pakistan, had agreed to refrain from threats and violence in violation of the line of control in Jammu and Kashmir.
