I heard that Asian and Middle East countries are buying vast areas of Africa because they want to grow food.
In Israel there are a lot of refugees from Sudan and Eritrea, over the last few years we have employed a few of them and they are nice people and great workers.     I see no reason that setting up a factory there shouldn't  work.      South Africa was a prosperous nation with a African workforce.      Problem in Africa is corruption, elected officials steal the money instead of building infrastructure.
I print shirts for a guy in Ghana, he says you can't do anything without paying someone.     If you want to clear a parcel from customs, you have to pay.
