You are the eternal optimist,Pole.
I plain don't trust Communists period.
Did you ever read Che's Africa Diaries?He was very contemptuous of African people.Seems they weren't disciplined enough to be "real"revolutionaries.
I think the Chinese just can't help their own racism and sense of superiority when it comes to Africans.
Hell,the Chinese Americans I know will in their moments of honesty tell you that most Chinese think they are more gifted than white people,not to mention blacks and Latinos.
Present day Chines has mixed system where people can have their own business and usually they are free to travel. Very different from Maoism or Stalinism. (BTW, I grew up under psot Stalin Communism so I have some personal insight)
And there is a very easy way to prevent Chinese inroads into Africa: Western countries should offer Africa BETTER deal. Simple like that!
