Cuba is evaluating a move to end restrictions on Cubans' tourist trips abroad, according to a reform plan drafted in last month's Communist Party congress and published Monday, according to dpa. Cuba has limited its citizens' trips abroad for half a century. Since the revolution that brought Fidel Castro to power in 1959, Cubans' travels off the island have been gradually limited to only allow migration abroad and business trips. In the 1970s and 1980s, Cubans could take collective trips to the Soviet Union and other countries within the Soviet bloc. Nowadays, to be able to travel abroad, Cubans need letters of invitation filed at the relevant Cuban consulate by their host, and their exit needs to be approved by Cuban authorities. There is no specific timetable regarding plans to ease restrictions on travel. It also remains to be seen how Cuban authorities intend to handle the case of dissidents, who are regularly denied permission to leave the island. The reforms approved by the Communist Party Congress includes separate measures on buying and selling homes and vehicles among private citizens, a practice which is not allowed in Cuba. The congress' proposals have yet to be made law.
