Also until the late 1960s, the official term for Comecon activities was "cooperation". The term "integration" was always avoided because of its connotations of monopolistic capitalist collusion. After the "special" council session of April 1969 and the development and adoption (in 1971) of the Comprehensive Program for the Further Extension and Improvement of Cooperation and the Further Development of Socialist Economic Integration by Comecon Member Countries, Comecon activities were officially termed "integration" (equalization of "differences in relative scarcities of goods and services between states through the deliberate elimination of barriers to trade and other forms of interaction"). Although such equalization had not been a pivotal point in the formation and implementation of Comecon's economic policies, improved economic integration had always been Comecon's goal.
