"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. The government of Raúl Castro has implemented limited economic policy changes, 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 expect the government to ease its tight control over the political system. The government has reduced the number of political prisoners over the past several years, but short-term detentions and harassment have increased significantly."
