"Cuba remains a one-party communist state with a poor record on human rights. The country's political succession in 2006 from the long-ruling Fidel Castro to his brother Raúl was characterized by a remarkable degree of stability. In February 2013, Castro was reappointed to a second five-year term as president (until 2018, when he would be 86 years old), and selected 52- year old former Education Minister Miguel Díaz-Canel as his First Vice President, making him the official successor in the event that Castro cannot serve out his term. Raúl Castro has implemented a number of gradual economic policy changes over the past several years, including an expansion of self-employment. A party congress held in April 2011 laid out numerous economic goals that, if implemented, could significantly alter Cuba's state-dominated economic model. Few observers, however, expect the government to ease its tight control over the political system. While the government reduced the number of political prisoners in 2010-2011, the number increased in 2012; moreover, short-term detentions and harassment have increased significantly over the past several years."
