The WAEMU competition policy is, from the point of view of material and procedural law, in conformity with international standards, with certain specificities relating to the control of concentrations, the establishment of a special category of anti-competitive practices attributable to States and, above all, a centralized institutional approach with almost exclusive competence of the Community bodies. Then, eighteen (18) years (2003-2021) after the adoption of the implementing texts, WAEMU competition policy has therefore contributed to the consolidation of the Customs Union, the free movement of goods and liberalization in several sectors of activity (telecommunications, communication, energy, etc.). Moreover, it has become an essential tool for promoting regional economic integration in the Union.
