The deal has been criticized in India for not containing a non-war pact or a renunciation of guerrilla warfare in Kashmir. After the signing of the agreement, Indian Prime Minister Lal Bahadur Shastri died mysteriously in Tashkent.  Shastri`s sudden death led to persistent conspiracy theories that he was poisoned.  The Indian government refused to publish a report on his death, arguing that it could affect foreign relations, disrupt the country and violate parliamentary privileges.  Tashkent Agreement (January 10, 1966), signed an agreement between Indian Prime Minister Lal Bahadur Shastri (who died the next day) and Pakistani President Ayub Khan, which ended the 17-day war between Pakistan and India from August to September 1965. On September 22, the United Nations Security Council announced that it had done so. An armistice was concluded in September 1965. The Tashkent Declaration “did not lead to a solution to the crisis,” says Peter Topychkanov. Peace between the two countries lasted six years. In 1971, a new military conflict broke out between India and Pakistan, which led to the secession of its eastern part from Pakistan, over which the state of Bangladesh was proclaimed. In December 1971, a new armistice was signed between the parties. Relations between India and Pakistan remain strained, and the state of Jammu and Kashmir remains a hotbed of ever-emerging cross-border conflicts.
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 in Kashmir. The two countries agreed not only to withdraw their troops from each other`s territory and take back their prisoners of war, but also to begin normalizing diplomatic relations. Unfortunately, the proposed start of India-Pakistan friendly relations was complicated by Shastri`s death just hours after the agreement was signed. The agreement has done little to mitigate the deep hostility between the two countries since their independence in 1947 and did not prevent the outbreak of new hostilities in 1970. IV The Prime Minister of India and the President of Pakistan agreed that both sides will discourage any propaganda directed against the other country and promote propaganda that promotes the development of friendly relations between the two countries. After independence from British rule, India remained a constant threat to Pakistan`s security, as Congress leaders soon began to reverse partition. India illegally conquered many parts of Pakistan by hook or crooks, and one of these disputed areas was the state of Kashmir. The first war for Kashmir took place in 1947-1948. The second war took place in 1965 on the same issue, which was a manifestation of the inherent hostility between the neighbors. The war began on September 6 with India crossing Pakistan across the international border in the darkness of the night. In seventeen days, thousands of people on both sides were wiped off the earth. The United States and the Soviet Union forced the UN to do its part for the peaceful solution and forced it to an amicable solution to all the problems between the two countries, because the war affected world peace.
The efforts of the United Nations brought peace because both countries agreed to the ceasefire. In addition, Soviet Prime Minister Alexei Kosygin also played an important role in bringing countries to the negotiating table when he invited both sides to Tashkent. However, diplomatic efforts have been successful and India and Pakistan have signed the Tashkent Declaration, which urged both countries to cease hostilities, withdraw all forces from positions they occupied before the start of the conflict and resume diplomatic relations. The agreement was negotiated by Soviet Prime Minister Alexei Kosygin, who had invited the parties to Tashkent. The parties agreed to withdraw all armed forces from positions held prior to 5 August 1965; the re-establishment of diplomatic relations; and discuss economic, refugee and other issues. The deal has been criticized in India for not containing a war treaty or renunciation of guerrilla aggression in Kashmir. Tashkent, 10 January 1966The Prime Minister of India and the President of Pakistan, who met in Tashkent and discussed the existing relations between India and Pakistan, hereby declare their firm determination to restore normal and peaceful relations between their countries and to promote understanding and friendly relations among their peoples. They consider the achievement of these goals to be crucial for the well-being of the 600 million people in India and Pakistan.I The Prime Minister of India and the President of Pakistan agree that both sides will make every effort to establish good-neighbourly relations between India and Pakistan in accordance with the Charter of the United Nations.
They reaffirm their commitment under the Charter not to use force and to settle their differences by peaceful means. They believed that the interests of peace in their region, and especially in the Indo-Pakistani subcontinent, and indeed the interests of the peoples of India and Pakistan, were not served by the persistent tensions between the two countries. .
