Ryan Musser writing in CIPE:
Reducing tariffs is a great start for increasing trade within Africa, but important non-tariff barriers (NTBs) must also be reduced in order to boost trade both within and outside of the continent. In fact, the United Nations Economic Commission for Africa found the costs of NTBs in 2010 were higher than the costs of tariffs. The African Development Bank notes that, “while tariffs have progressively fallen, the key challenge to intra-African trade is non-tariff barriers that stifle the movement of goods, services and people across borders.”
