I'm not following any of your statements. They don't seem to relate to each other either.
I am not sure what you mean by "Africa is a complex problem", there is no singularity there. Africa is also not "a problem." I am not even sure I know what that means.
The Chinese aren't bribing anyone, they are actually building much-needed infrastructure. These are real tangible things they are delivering The problem is they are doing it in exchange for access to the natural resources in those countries, the extent of which is often not well understood.
You saying "we moved our manufacturing" leads me to believe that you are American. This is not the same as whats going on in sub-Saharan Africa with infrastructure projects at all. American companies reap significantly higher profit margins by manufacturing in China. In a sense America has "completed its industrialization" and is now largely a service economy. much of Africa is considered a "developing economy", those natural resources and the wealth that they could generate should benefit the African not the Chinese.
Kagame is not a "strongman"(I dislike that US media term.) He's been in power way too long for sure but he is not a military thug which is the general connotation of that term. A lot of good has actually happened for Rwanda under his leadership and compared to neighboring Burundi things run pretty well there. Kagame is not a puppet of any former colonial power nor is Kabilia for that matter.
