His brother, Acting President Raul Castro said earlier this week that the ailing revolutionary leader is "irreplaceable."
But Raul Castro added that the revolutionary generation has a duty to pass the leadership on to a younger generation, whether it wants to or not.
Fidel Castro made his brother acting president in late July while recovering from intestinal surgery. Details of the 80-year-old's health are closely guarded.
The director of U.S. national intelligence, John Negroponte, has said that Mr. Castro is very ill and could die within months, rather than years.
