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 India, the people also criticized the agreement because the Pakistani president and the Indian prime minister did not sign a guerrilla pact in Kashmir. After the day of this declaration, Prime Minister Lal Bahadur died on the day of a sudden heart attack. After him, no one accepted this statement, and it was ignored by the next government. 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. 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. Protests and riots took place at various locations in Pakistan.  To dispel the anger and concerns of the people, Ayub Khan decided to take the matter before the people on 14 January 1966. This is the difference with Tashkent`s statement that eventually led to the impeachment of Zulfikar Ali Bhutto from the Ayub government, which later founded his own party, the Pakistan People`s Party. Although Ayub Khan was able to satisfy the concerns of the people, Tashkent`s declaration significantly tarnished his image and was one of the factors that led to his downfall.  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 Tashkent Declaration was a peace agreement between India and Pakistan, signed on 10 January 1966, which resolved the 1965 Indo-Pakistan war.
