In accordance with the Tashkent Declaration, ministerial talks were held on 1 and 2 March 1966. Despite the fact that these discussions were unproductive, diplomatic exchanges continued throughout the spring and summer. No results were achieved as a result of these discussions, due to differences of opinion on the Kashmir issue. The news of the Tashkent declaration shocked the people of Pakistan who expected more concessions from India than they received. Things got even worse when Ayub Khan refused to speak out and went to solitary confinement instead of announcing the reasons for signing the agreement. Protests and riots broke out in different locations across Pakistan.  To appease the anger and concerns of the people, Ayub Khan decided to take the matter to the people on January 14, 1966 by addressing the nation. It was the difference on the Tashkent declaration that eventually led to Zulfikar Ali Bhutto`s withdrawal from Ayub`s government, who later founded his own party called Pakistan People`s Party. Although Ayub Khan was able to satisfy the concerns of the people, the Tashkent declaration severely tarnished his image and was one of the factors that led to his downfall.  Indian Prime Minister Lal Bahadur Shastri and Pakistani President Ayub Khan met in Tashkent on January 4, 1966.
The two leaders signed a pact called the Tashkent Declaration of 1966. Tashkent Agreement (January 10, 1966), an agreement signed by Indian Prime Minister Lal Bahadur Shastri (died the next day) and President Ayub Khan of Pakistan, which ended the 17-day war between Pakistan and India from August to September 1965. A ceasefire was adopted by the United Nations Security Council on September 22, 1965. VI The Prime Minister of India and the President of Pakistan agreed to consider measures to restore economic and trade relations, communications and cultural exchanges between India and Pakistan and to take measures to implement the existing agreements between India and Pakistan. Lal Bahadur Shastri (1904-1966) Prime Minister of India The agreement was negotiated by Soviet Prime Minister Alexei Kossygin, who had invited the parties to Tashkent. The parties agreed to withdraw all armed forces from posts held before 5 August 1965; re-establish diplomatic relations; and to discuss economic, refugee and other issues. The deal was criticized in India for not containing a non-war pact or renunciation of guerrilla aggression in Kashmir. In India too, the people criticized this agreement because the Pakistani president and the Indian prime minister did not sign a guerrilla pact in Kashmir. After the day of this statement, Prime Minister Lal Bahadur died of a sudden heart attack. After him, no one accepted this statement and it was ignored by the next government. An agreement signed in the Soviet city of Tashkent by Indian Prime Minister Lal Bahadur Shastri and Pakistani President Ayub Khan to end the Second Indo-Pakistani War for Kashmir.
The two countries agreed not only to withdraw their troops from the territory of the other and recover their prisoners of war, but also to begin to normalize diplomatic relations. Unfortunately, Shastri`s death, just hours after the signing of the agreement, made it more difficult for India and Pakistan to begin friendly relations. The agreement has done little to ease the deep hostility between the two countries since their independence in 1947 and did not prevent the outbreak of new hostilities in 1970. The Tashkent Declaration was a peace agreement signed on January 10, 1966 between India and Pakistan, which resolved the Indo-Pakistani War of 1965. .
