I'm not sure. They'll build infrastructure that's pretty much a given.Once the corrupt leaders in Africa allow China to buy up the place the Africans will have the shock of their lives. They'll be pleading for Ian Smith to be resurrected.
I don't see how making things worse for Africans is in China's self-interest. The question is whether they can make improvements that last. Europeans built infrastructure all those years ago and a lot of it has long since fallen into disrepair. Will it be the same story this time around?
