In the past, policy advice on promoting trade in Africa may have overstressed the need for African countries to bring down their own trade barriers, such as import tariffs, and insufficiently emphasized the need to improve trade logistics, infrastructure, business competition, and regulation. As I mentioned in a recent interview, lowering tariffs may not help if it takes an average of four days to clear goods at the port of Mombasa, Kenya. It can take up to 21 days for a vessel to offload its cargo at Dar es Salaam port. Given the large number of landlocked countries in Africa, poor infrastructure—such as road and communications networks—could be as much a barrier as trade tariffs.
