The treaty was signed in 1972 in Simla (also spelt "Shimla" in India) by Zulfiqar Ali Bhutto, the President of Pakistan, and Indira Gandhi, the Prime Minister of India. The agreement also paved the way for diplomatic recognition of Bangladesh by Pakistan. Technically, the document was signed at 0040 hours in the night of 3 July; despite this official documents are dated 2 July 1972. Some of the major outcomes of the Simla Agreement are:
The agreement has not prevented the relationship between the two countries from deteriorating to the point of armed conflict, most recently in the Kargil War of 1999. In Operation Meghdoot of 1984 India seized all of the inhospitable Siachen Glacier region where the frontier had been clearly not defined in the agreement (possibly as the area was thought too barren to be controversial); this was considered as a violation of the Simla Agreement by Pakistan. Most of the subsequent deaths in the Siachen Conflict have been from natural disasters, e.g. avalanches in 2010, 2012, and 2016.
Simla Agreement on Bilateral Relations between India and Pakistan signed by Prime Minister Indira Gandhi, and President of Pakistan, Z. A. Bhutto, in Simla on 2 July 1972.
The Government of India and the Government of Pakistan are resolved that the two countries put an end to the conflict and confrontation that have hitherto marred their relations and work for the promotion of a friendly and harmonious relationship and the establishment of durable peace in the subcontinent so that both countries may henceforth devote their resources and energies to the pressing task of advancing the welfare of their people.

Pending the final settlement of any of the problems between the two countries, neither side shall unilaterally alter the situation and both shall prevent the organization, assistance or encouragement of any acts detrimental to the maintenance of peace and harmonious relations.

(i) Indian and Pakistani forces shall be withdrawn to their side of the international border.
(ii) In Jammu and Kashmir, the line of control resulting from the ceasefire of 17 December 1971, shall be respected by both sides without prejudice to the recognized position of either side.
