Promoting African regional integration has been long on the agenda of African policymakers, and was embedded at the creation of the Organisation of African Unity (OAU) in 1963.

At present, there are eight RECs recognised by the African Union (AU). 2 Subsequent stages involved establishing a free trade area among these RECs that would, by 2017, become a customs union-i.e. to maintain a common external tariff for imports from third countries as well as to implement common customs and trade policies. Eventually, by 2019, a continental customs union would be established, followed by an African Common Market with the adoption of common policies in areas such as energy, transportation, communication, and agriculture, with harmonised monetary, financial, and fiscal policies and the free movement of persons, goods, capital, and services.At present, two RECs operate as customs unions, namely the East African Community (EAC) and the Economic Community of West African States (ECOWAS).
