According to the African Development Bank, inter-African trade made up just 16% of the continent’s total trade in 2014. That figure has increased from 10% in 2004, but it is still low compared with other regions of the world. Among the bits of the continent that lose out worst are landlocked countries and areas such as Lake Tanganyika, which are far from both their capital cities and the sea. Poor infrastructure is not the only problem—bureaucracy and other trade barriers matter, too—but it is a significant one. According to a World Bank review, “landlocked developing countries, especially in Africa, bear exorbitant transport costs”.
