Bloomberg Businessweek has hit American companies trying to do business in Cuba, outlining a shaky environment and Cuba’s thirst for quick cash investments.

In the article, viewable here, Businessweek also said that: “Carnival Cruise Line signed a memorandum with Cuba, outfitted and staffed a 704-passenger ship, and hinted that it could make Cuba the center of its entire Caribbean operations. The Cubans have stalled by not forming a corporate partner, have demanded from Carnival massive investments in their ports, and let deadlines for the first sailings float away.”
