It'll be good for Africa. Maybe it's a chance for Africa to turn itself around, by giving them more competition (they can't blame the White Man anymore either). The Chinese didn't get to be the world's largest ethnic group by coincidence. If the Black Africans don't get their act together quickly, they might just find that they are minorities in their own continent.
Yeah, just wait until the Chinese farmers are successful and Mugabe can take their land away and renege on promises.
