Bulgaria's communist government plans to sell shares of its publicly owned enterprises to foreign investors as part of the widespread economic changes sweeping Eastern Europe, a U.S. official says. Deputy Secretary of State John Whitehead said that during his trip to Bulgaria, President Todor Zhivkov disclosed plans to turn government-owned enterprises into corporations that will offer stock to their employees and other investors. "Marx would have turned over in his grave if he could have heard Comrade Zhivkov talk that way," Whitehead told reporters in Brussels. Bulgaria has traditionally been the Soviet Union's most loyal satellite in Eastern Europe and changes there likely reflect Soviet approval. Whitehead said, "There is change everywhere in Eastern Europe, that is the key word of my conclusions: economic change, political change and social change."
