The Tashkent Declaration was a peace agreement between India and Pakistan to resolve the 1965 Indo-Pakistan war (August 5, 1965-September 23, 1965). It was signed in Tashkent, the capital of Uzbekistan, which in turn was part of one of the republics of the USSR. The main objective was to restore economic and diplomatic relations in the countries concerned, to stay away from the internal and external affairs of the other and to work towards the advancement of bilateral relations. The declaration only ended the hostilities between India and Pakistan, but left the issue of Kashmir between the two, and neither side has been able to reach an agreement to date. The first Indo-Pakistan War, known as the First Kashmir War (October 22, 1947-January 5, 1949), took place shortly after the independence of India and Pakistan. A ceasefire agreement has led to the establishment of the Line of Control (LOC) as the de facto border between India and Pakistan in Kashmir. VI The Indian Prime Minister and the President of Pakistan agreed to consider measures to restore economic and trade relations, communication and cultural exchanges between India and Pakistan and to take steps to implement existing agreements between India and Pakistan. The Tashkent Declaration was a peace agreement between India and Pakistan, signed on 10 January 1966, which resolved the 1965 Indo-Pakistan war. Peace was achieved on 23 September by the intervention of the external powers that pushed the two nations to the truce, lest the conflict intensify and attract other powers.
 The agreement was criticized in India because it did not contain a war node or renouncement of guerrilla warfare in Kashmir. After the signing of the agreement, Indian Prime Minister Lal Bahadur Shastri mysteriously died in Tashkent.  Shasti`s sudden death led to persistent conspiracy theories that he was poisoned.  The Indian government refused to downgrade a report on his death claiming that it could harm foreign relations, cause disruption in the country and a violation of parliamentary privileges.  The agreement was negotiated by Soviet Prime Minister Alexei Kosygin, who had invited the parties to Tashkent. The parties agreed to remove all armed forces from positions that were occupied before August 5, 1965; Renewing diplomatic relations; and to discuss economic, refugee and other issues. The agreement was criticized in India because it contained no war pact or renouncement of guerrilla aggression in Kashmir. In accordance with Tashkent`s statement, ministerial talks were held on 1 and 2 March 1966. Despite the fact that these talks were unproductive, diplomatic exchanges continued in the spring and summer. The results of these discussions were not obtained due to differences of opinion on the Kashmir issue.
The news of Tashkent`s statement shocked the people of Pakistan, who expected India to make more concessions than they got. Things got even worse when Ayub Khan refused to speak and went to solitary confinement instead of announcing the reasons for signing the agreement.
