hmm I believe its a bit more complicated than that. In one hand you have the chinese buying land and taking resources, on the other, technology is not designed and produced there, which implies big manufacturers are very happy to sell their technology there, but never allowing them to opose as competition. Like in many other regions of the world, potential investors are not expecting to reinvest on Africa, they are expecting to get their profits out of there as soon as possible, leaving the young people there as poor as they met them.
Thanks for the post.
