Other examples of landlocked dependency are the difficulties Mali faced in order to export its goods in the 1990s as nearly all its transit neighbours (Algeria, Togo, Ghana, Sierra Leone, Liberia, Guinea and Côte d'Ivoire) were effectively engaged in civil conflict around the same time and the Central African Republic, where its travel routes for export depend on the season, as during the rainy season Cameroon’s roads are too poor to travel on and during the dry season the Democratic Republic of Congo’s Oubangui River water levels are poorly maintained for adequate maritime travel.
