Relations between the Soviet Union and Bangladesh were good in the years immediately after Bangladesh's independence in 1971. The Soviet Union supported Indian actions in aiding the war of liberation, and after the war the Soviet Navy sent a floating workshop to Bangladesh for clearing Pakistani mines from the Chittagong and Chalna harbors. Mujib visited Moscow in 1972, and high-level officials from both countries made numerous reciprocal visits until 1975. The Soviets supported the socialist programs of the Mujib government and its very exceptionally close ties with India. Early Soviet aid was limited, however. During the first four months of its existence, Bangladesh received economic aid worth US$142 million from India, but only US$6 million from the Soviet Union.
