Stability is important, however in a sourcing system where the international corporation does little more than source products, and locals provide the labor and captial, it matters far less.

Far more important would be the costs of transportation.   Africa has long coastlines, but how many cities have the infrastructure needed to transport goods to export points (ports, railroads for export to Europe, etc)  If the transportation infrastructure doesn't exist then the additional costs of transportation have to be subtracted from the lower labour costs.
