Common Market for Eastern and Southern Africa, COMESA Common Market for Eastern and Southern Africa (COMESA) The Common Market for Eastern and Southern Africa traces its genesis to the mid 1960s. The idea of regional economic co-operation received considerable impetus from the buoyant and optimistic mood that characterised the post-independence period in most of Africa. The mood then was one of pan-African solidarity and collective self-reliance born of a shared destiny. It was under these circumstances that, in 1965, the United Nations Economic Commission for Africa (ECA) convened a ministerial meeting of the then newly independent states of Eastern and Southern Africa to consider proposals for the establishment of a mechanism for the promotion of sub-regional economic integration. The meeting, which was held in Lusaka, Zambia, recommended the creation of an Economic Community of Eastern and Central African states.
