hello
shareholding can be either in a PLC or SC,
1. in a normal PLC you will have to go mainly according to the Investment proclamation,
a.) a Joint venture with a non ethiopia will request 150.000 USD Investment (refers to the Project), now depending on your shareholding you can calculate your part
b.) beside the ruels and Regulation this entety will be mainly regulated by the article and Memorandum the two Basic contracts. Most People use very simple once, which are circulating since years in Ethiopia, indeviduall Regulation are unknown, even lawyers use this simple documents - highly risky!! for non Ethiopians. Every Thing which is not regulated will go according to the Commercial law of Ethiopia.
2. S.C their are some public share companies, selling Shares, this is regulated with the so called "prospect" but, a big but, Ethiopia has no Regulation authoreties controling this as you find on the international stock market such as London or Frankfurt!
Basicaly I can make it short, don t do it. If you invest and this with a local Partner do it with a min of 51% Shares, no way arround.
