China says it has a 'zero-tolerance policy' for racism, but discrimination towards Africans goes back decades

(CNN)A black version of the Chinese flag swept across African Twitter earlier this month, as users replaced their avatars to express their anger at the government of China.

They were outraged not only by widespread reports of coronavirus-related discrimination against Africans in China, but also by claims on Chinese state media that the allegations were "groundless rumors."
Posting under the hashtag #BlackChina, Dennis Kiplomo, a nurse from Kenya, tweeted: "We expect the kind of hospitality we give to Chinese here in Africa, be reciprocated in their home country."
    Another user in Kenya, Peter Kariuk, wrote: "We need a united Africa which will not be slaves of #BlackChina."
      The southern Chinese city of Guangzhou has Asia's largest African population. While the exact number of Africans living in Guangzhou is unknown, in 2017 more than 320,000 Africans entered or left China through the city, according to state news agency Xinhua.
