Editing Fidel Castro (section)

====Government reform====
In a dire economic situation, the Cuban government turned to the Soviets for help. From 1970 through to 1972, Soviet economists re-planned and organized the Cuban economy, founding the Cuban-Soviet Commission of Economic, Scientific and Technical Collaboration, while Soviet Premier Alexei Kosygin (1904–1980) visited Cuba in late 1971. In July 1972, Cuba would successfully apply for membership of the Council for Mutual Economic Assistance (Comecon), an economic organization of socialist states, although this move only served to further limit Cuba's economy to agricultural production. Aside from the economy, Castro's Cuba also faced other problems in the early 1970's: in May 1970, Alpha 66, a militant Cuban dissident group based in Florida, sank two Cuban fishing boats and captured their crews, demanding the release of Alpha 66 members imprisoned in Cuba. Under U.S. government pressure, the hostages were released, with Castro welcoming them back as heroes. In April 1971, Castro gained international condemnation after ordering the arrest of Herberto Padilla, a Cuban poet who had won an international prize but whose views were critical of the government. Padilla fell ill, with Castro visiting him in hospital; soon after, the poet publicly confessed his guilt and was released. Soon, the government formed the National Cultural Council through which it ensured that intellectuals and artists produced work that supported their administration. In 2006, he left his ruling status to his brother Raúl, who was leader until 2018.
