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. Although the agreement called for the repatriation of Russian-speaking biharis to Bangladesh, the Pakistani government withdrew its promise to relocate the Community to Pakistan.  This led to the stateless Pakistani community stranded in Bangladesh. The treaty came into force on August 8, 1973 and expired on July 1, 1974. Under the agreement, UNHCR oversaw the repatriation of citizens from Bangladesh and Pakistan. According to the UN, 121,695 Bengalis have been transferred from Pakistan to Bangladesh. Among them are senior Bengal officials and the military. 108,744 civilians and non-Bengali officials were transferred from Bangladesh to Pakistan.
 India released 6,500 Pakistani PoWs, most of whom were transported by train to Pakistan. In 1974, General Niazi was the last Pakistani officer to be symbolically returned by the Wagah border.  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 Delhi Agreement was a trilateral agreement signed on 28 August 1973 between India, Pakistan and Bangladesh. and only ratified by India and Pakistan.  It allowed the repatriation of prisoners of war and interned officials held in the three countries after Bangladesh`s war of liberation in 1971. The agreement was criticized because Pakistan did not repatriate Urdu spokesmen to Bangladesh and failed to bring to justice 195 high-ranking military personnel accused of being admitted to the war.  Among the PoW, 195 Pakistani military officers detained in India have been identified as the main suspects in war crimes.
Pakistan insisted that they be released as one of its main demands. She urged several Muslim countries to refuse recognition of Bangladesh until the release of the 195 officers.  India preferred their repatriation to Pakistan. In the text of the agreement, Bangladeshi Foreign Minister Kamal Hossain said: (iv) The Indian Prime Minister and the President of Pakistan agreed that both sides would deter any propaganda against the other country and encourage propaganda that would promote the development of friendly relations between the two countries. After the failure of the operation and the discovery of Pakistani infiltration, India launched a large-scale military attack on Western Pakistan, which invaded Pakistani Punjab and struck Pakistani forces, triggering the 1965 Indo-Pakistan war, the first major engagement between the two neighbouring states since the 1947-48 Indo-Pakistan war.  After the First Kashmir War (1947-1948), in which India maintained more than two-thirds of Kashmir, Pakistan sought a chance to reach the remaining territories of Kashmir. The opening took place after the Chinese-Indian War of 1962, after India`s war with China, and as a result, the Indian army underwent massive changes in personnel and equipment. During this period, the Pakistani armed forces, although smaller in number than the Indian army, had a qualitative lead in air power and armament over India which Pakistan was trying to exploit before India completed its defence. The Rann von Kutch episode of the summer of 1965, in which Indian and Pakistani troops met, yielded positive results for Pakistan.
