Cons
COMESA being an intergovernmental organisation rely on the member states to approve anything that the secretariat undertake. Since Member states are sovereign entities, the secretariat can not impose anything to them. Decisions have to be made once everyone agree or at least the majority. Thus, this can cause delays in programme implementation. Another downside, the secretariat is still runned in analog manner. Most of the process and approval are done manually.
