"Not right at all because the African will have inferior teaching credentials"

If you'd have worked with any Africans in China you'd know that their qualifications were inferior. But that's all academic because nobody understands what they are trying to say- they can't get past that first very important hurdle. That said the whole question is becoming academic since the Chinese are replacing Africans with Eastern Europeans, who will lead the students up the garden path concerning grammar and speech but we can understand what they say and I suppose the latter attribute has become attractive to the Chinese- that, and they come cheap like Africans.
