Cuba NPR's Tom Gjelten reports that the president of the U.S Chamber of Commerce visited Communist Cuba this week. Thomas Donohue spent three days in Cuba, meeting with private entrepreneurs, dissidents and government officials, including Fidel Castro. Donohue says he tried to encourage the expansion of private enterprise in Cuba, but acknowledged that leadership there seems to have limited interest in free market reforms. Still, Donohue argues the time is right to lift the U.S trade embargo against Havana. He says the Chamber will push for a national debate on US Cuba policy.
