Abstract
Since mid-1989, remarkable political and economic changes have occurred in the Soviet Union and Eastern Europe. Although the countries differ with regard to the scope, speed, and sequence of these changes, in the economic arena the objective is, in all cases, to abandon traditional central planning and replace it with a market economy. An integral component of these efforts to establish markets is the reform of foreign economic relations and greater involvement in the world economy.While a tide of political and economic change has swept the East, Cuba has adamantly held on to a one-party political system and to orthodox central planning.
