I betya in some strategy meeting in paypal, it was decided to shut down all African countries. Someone clicked some buttons and that's the end of access from Africa.
The Chinese would work differently - they'd still try to squeeze whatever juice can still be got out that. Africa is increasingly becoming Dubai/China focused, and at some point the west will realise that a huge market does not recognize them as viable business partners anymore.
Consider Dubai as a pivoting point for India/China and Africa. That's a new center of the world that is developing independently of the west.
