The program was not a success. "The Gorbachev regime made too many commitments on too many fronts, thereby overstretching and overheating the Soviet economy. Bottlenecks and shortages were not relieved but exacerbated, while the (Central and) East European members of Comecon resented being asked to contribute scarce capital to projects that were chiefly of interest to the Soviet Union…" Furthermore, the liberalization that by June 25, 1988 allowed Comecon countries to negotiate trade treaties directly with the European Community (the renamed EEC), and the "Sinatra doctrine" under which the Soviet Union allowed that change would be the exclusive affair of each individual country marked the beginning of the end for Comecon. Although the Revolutions of 1989 did not formally end Comecon, and the Soviet government itself lasted until 1991, the March 1990 meeting in Prague was little more than a formality, discussing the coordination of non-existent five-year plans. From January 1, 1991, the countries shifted their dealings with one another to a hard currency market basis. The result was a radical decrease in trade with one another, as "(Central and) Eastern Europe… exchanged asymmetrical trade dependence on the Soviet Union for an equally asymmetrical commercial dependence on the European Community."
