China will do as well as all the other colonial powers did in Africa.
Key differences between China and previous colonization efforts:
1. China not limited to early 1900's methods of transportation, farming, infrastructure and building.
2. Chinese, being non-white, are "investors" and "immigrants" rather than colonists.
3. Chinese have less concern over human rights and self-determination of other nations.
4. Chinese have even more need to expand into other lands than did Europeans and Arabs.
5. China's engineered shortage of females further impels expansion and generation of mixed race people with loyalty to China.
Similarity:
Only one (possible): Colonization may be checked by defeat or reduction of power after a world war (such as many European nations).
This will be simple resource exploitation, and last time I looked, blacks aren’t a resource.
