No, I think Africa is mostly a business opportunity, sans a few places which have structural political problems which could be best addressed through high-velocity physics demonstrations. But it's undeniable that the US v. USSR caused a lot of problems during the cold war (Angola, etc), including propping up a lot of bad leaders or supporting revolutions.
I don't think it will be "plundered", though -- the foreigners (white and Asian) doing business going to Africa are making life better for everyone.
There are a lot of NGOs and UN organizations still operating in Africa which don't help (and never really helped). But there are small, usually religious, charities who are also doing good, just like they do in Asia, Europe, and the US.
