Yet Soviet interaction with the West increased, motivated in part " by the Soviets' need to remain abreast of scientific and technological advances. Foreign exchange students and scholars, foreign tourists, foreign goods, and selected foreign films grew more commonplace, especially in Moscow and Leningrad.

Young people's desire for consumer goods (jeans, especially), rock music, and other products of the capitalist world troubled the regime and created a generation gap similar to that in Europe and the United States.
