The Abuja Treaty (1991) for the establishment of the African Economic Community recognizes the cooperation between African customs administrations as a key element for the correct functioning of the future Community, calling (Art. 39) for the development of a Protocol to define criteria and modalities for such cooperation. Despite this Protocol was never adopted, in 2004 the African Union decided to create a sub-committee of Directors General of Customs as a mechanism to facilitate the coordination among customs services in the continent. The creation of this committee was anticipated by a meeting of the Directors General of Customs of the AU member states held in 2003 in Johannesburg as part of the "All Africa Customs Conference" (AACC), in which for the first time discussions were held on how to improve cooperation practices among African Customs as part of advancing the continent’s economic integration process.
