You're terribly wrong, and seems you're totally unaware of the true history!
Please keep the facts straight before going on with further disillusion.
They were the White people, first the Europeans and later succeeded by the Americans, who enslaved the Africans and their descendants, today known as the Black or "dark skinned" people for centuries!
The African are still poor until today because the White looted and raped their people and resources to the extreme levels and leaving behind only the bad things and severely divided legacies and boundaries there.
Sorry, neither the Chinese nor any other race involved with regard to these atrocities.
