Of course, if you want to wait until African nations have governments as stable and political systems as developed as those of Western European nations, then you virtually wouldn't be able to have relations with any nation in the continent. Still, nations must meet certain reasonable criteria before you can start to talk about establishing diplomatic relations.
當然如果你要等非洲所有的國家政權穩定、制度健全，達到像西歐先進國家一般，那麼幾乎沒有一個國家可以建交，所以只要評估到一個相當的程度也就可以開始談。
