Cuba's foreign policy has been fluid through history depending on world events and other variables, including relations with the United States. Without massive Soviet subsidies and its primary trading partner, Cuba was comparatively isolated in the 1990s after the fall of the USSR and the end of the Cold War, but has since entered bilateral co-operation with several South American countries, most notably Venezuela and Bolivia. The United States used to stick to a policy of isolating Cuba until December 2014, when Barack Obama announced a new policy of diplomatic and economic engagement. The European Union accuses Cuba of "continuing flagrant violation of human rights and fundamental freedoms". Cuba has developed a growing relationship with the People's Republic of China and Russia. In all, Cuba continues to have formal relations with 160 nations, and provided civilian assistance workers – principally medical – in more than 20 nations. More than one million exiles have escaped to foreign countries. Cuba's present foreign minister is Bruno Rodríguez Parrilla.
Cuba is currently a lead country on the United Nations Human Rights Council, and is a founding member of the organization known as the Bolivarian Alternative for the Americas, a member of the Latin American Integration Association and the United Nations. Cuba is a member of the Non-Aligned Movement and hosted its September 2006 summit. In addition as a member of the Association of Caribbean States (ACS), Cuba was re-appointed as the chair- of the special committee on transportation issues for the Caribbean region. Following a meeting in November 2004, several leaders of South America have attempted to make Cuba either a full or associate member of the South American trade-bloc known as Mercosur.
