Côte d'Ivoire (often called Ivory Coast in English; see below about the name) is a country in West Africa. It borders Liberia, Guinea, Mali, Burkina Faso, and Ghana to the west, north, and east, and borders the Gulf of Guinea to its south. One of the most prosperous of the tropical West African states, its economic development has been undermined by political turmoil spawned by official corruption and refusal to adopt needed reforms.
