Caracas: Venezuelan President Hugo Chavez chatted, joked and sang with Cuba's new leader Raul Castro on Sunday and promised to continue supporting the country despite the retirement of his close friend Fidel Castro.

Raul Castro was named president of communist Cuba on Sunday, ending his brother Fidel Castro's 49-year rule but keeping the country on a communist path.

Soon after his acceptance speech in Cuba's National Assembly, Raul Castro spoke by phone on socialist Chavez's weekly live television show.

Chavez reaffirmed his commitment to Cuba and denied speculation that the two men did not get on well.
