India signed the Treaty of Peace, Friendship, and Cooperation in 1971 with the Soviet Union. This treaty established mutual strategic cooperation between India and the Soviet Union and marked a significant deviation from India's previous non-alignment policy during the Cold War. The treaty was instrumental in the geopolitical context of the 1971 Bangladesh Liberation War and was originally for 20 years, later renewed. It symbolized a close partnership and alignment of interests between the two countries in a period of regional and international challenges.
