Explain East Turkistan then, please.
A country is oppressing an ethnic minority. That's done in plenty of countries right now, including America. Ever heard of Sheriff Joe Arpaio? The question was about an openly racist major power. "One which openly considers and states that certain races or ethnic groups as biological inferior." China is oppressing the Uyghurs because the government believes that the Uyghurs' culture comprises a separate nationality from Chinese nationality and is a threat to Chinese territorial integrity. Not because they believe the Turkic or Altaic peoples to be a biologically inferior race.
