This paper analyzes the evolution of foreign direct investment [FDI] inflows for the Common Market for Eastern and Southern Africa [COMESA]. We focus especially on the impact of its creation in 1994 on FDI performances for each member of the organization. On the whole, the results are twofold. Firstly, the COMESA, as a group, has attracted more FDI inflows over the last decade. However the global performance remains largely unsatisfactory in comparison with the other regional trade agreements of the developing world. This situation is not surprising to the extent that many barriers to international investment are still present in Eastern and Southern Africa (macroeconomic and political instabilities, unsuitable economic policies, bad infrastructures, unreliable legal systems…). Secondly, the geographical distribution of FDI is strongly heterogeneous within the COMESA. The winners are clearly the countries which have enormous natural resources, such as oil exporting economies.
