[Developing countries] In 1972, despite improvement in recent years, the foreign trade of the former socialist countries with developing countries only amounted to 14.1% of their total export trade, and 10.0% of their import trade. In 1982, total foreign trade of socialist with developing countries amounted to 18.0%; while total foreign trade of developing with socialist countries only amounted to 3.7%. The desired expansion of trade between the former socialist and the developing countries continues to be limited by the inadequate complementarity of their respective economic structures.
