The joint enunciation of Panchsheel, the Five Principles of Peaceful Coexistence, by the Indian Prime Minister Nehru and the Chinese Premier Zhou Enlai on 29 April 1954 was a step in the direction of a stronger relationship between the two countries. 

The India-Pakistan Indus Waters Treaty was signed by Nehru and General Ayub Khan in 1960.

Henry Kissinger, the adviser to the US President Richard Nixon, made a secret visit to China via Pakistan in July 1971. In order to counter the US-Pakistan-China axis, India signed a 20-year Treaty of Peace and Friendship with the Soviet Union in August 1971.

With Bangladesh as a free country, India declared a unilateral ceasefire. Later, the signing of the Shimla Agreement between Indira Gandhi and Zulfikar Ali Bhutto on 3 July 1972 formalised the return of peace.
