HAVANA -- Fidel Castro says his comments about Cuba's communist economic model were misinterpreted by a visiting American journalist.

Appearing at the University of Havana on Friday, the 84-year-old ex-president says he meant "exactly the opposite" of the quote contained in a blog by Atlantic magazine reporter Jeffrey Goldberg.

Goldberg wrote Wednesday that he asked Castro if Cuba's economic system was still worth exporting to other countries. He said that Castro replied: "The Cuban model doesn't even work for us anymore."
