"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 2013, Raúl began his second and final five-year term, which is scheduled to end in February 2018, when he would be 86 years old. Castro has implemented a number of market-oriented economic policy changes over the past several years. A 2011 party congress laid out numerous economic goals that, if implemented, could significantly alter Cuba's state-dominated economic model; another party congress is expected in April 2016 that would likely focus on progress in implementing the 2011 guidelines and future economic measures. Few observers, however, expect the government to ease its tight control over the political system. While the government has released most long-term political prisoners, short-term detentions and harassment have increased significantly over the past several years, reflecting a change of tactics in repressing dissent."
