All I will say is that I am no lover of China. Chinese civilization, like Western civilization has exhibited anti-black tendencies and attitudes. The Chinese are great lovers of African markets, but not African people.
I do encourage you though to try to understand the African perspective on this issue, as well as other related issues that you may not generally understand before you try to characterize it as propaganda. Modern Africa is in a state of flux and deeply in need of infrastructure. There are many who say there are heavy costs to Chinese built infrastructure in Africa, Those same analysts will not reflect on the severe costs currently to Africa of its lack of infrastructures. The absence of intra-regional rail, highways, of connected electricity grids, of pipes and pipelines. If the West is truly concerned about African welfare, they can always step to the fore with their own expansive infrastructure agenda, but they largely won't, and we all know the reason why.
