Most countries in Southern Africa are net importers of products from South Africa and are therefore likely to be subject to South African cartels. Imports from South Africa cut across sectors including food, capital equipment, construction materials, energy, plastics and chemical products. Moreover regional markets are closely linked through the presence of South African companies in the rest of the region. This article expands on an earlier article in this Review on the possible impacts of some of the South African cartels on the region, as part of CCRED’s monitoring of competition case developments and the evolution of enforcement in the region.
