From April 8 to 10, 2020, in Havana, the 4th will be held. The Nation and Emigration Conference, continuity of that Dialogue of 78, promoted by the historic leader of the Cuban Revolution, Fidel Castro Ruz, which initiated a process of rapprochement between Cuba and the Cuban community abroad, which has been permanent and unwavering. Since then, more than 40 years and three conferences have passed, in which the links established on a premise set forth by Fidel have been strengthened: «(...) the Community must be respected. The community exists. The Community is a force and the Community is taken into account ».
