Yes. From what I have read Africans often experience blatant prejudice in China. The reports for the coronavirus are just another example.
For background, here is one story from several years ago:
As a former African-American expat living in China over a period of three years, I can remember horrible stories of racism experienced by other expats of African descent. One of the worst involved a brilliant young medical student from Guinea Bissau who studied Mandarin and medicine in the coastal city of Nanjing. This young medical student was fluent in Chinese and when she reported to a local Chinese hospital to do her residency and training, many of the Chinese patients would not allow her to touch them or treat them because she was African.
