Russia's president met with revolutionary icon Fidel Castro on Friday, discussing Guantanamo Bay and hopes for a multipolar world with Cuba's former leader during a tour of Latin America aimed at raising Moscow's presence in the region. Dmitry Medvedev spent hours talking and sightseeing with President Raul Castro before meeting privately with his 82-year-old older brother. Medvedev said he was happy with his visit when he left the island Friday evening on a flight from the beach resort of Varadero east of Havana, Cuba's Prensa Latina news agency reported. "We have defined what we are going to do next, we have cleared up everything regarding credits, and in Russia we will await President Raul Castro's visit," Prensa Latina quoted the Russian president as saying. The news agency offered no details about what had been defined and cleared up.
