Carola Binney, a Brit who spent a year teaching English in China, writes in The Spectator U.K.) that most Chinese are hopeless racists. As in India, light skin is associated with higher status. Those Han who are a shade or two darker are teased or ostracized. Non-Han minorities in China are likewise second class citizens.
Some find it shocking that people of European extraction aren't the only racists. In fact, those of us who've traveled know racism is pretty much the norm the world around. Places where it is uncommon are, bluntly, the exception. Claims of lack of racism should be treated as dubious. Hat tip to RealClearWorld for the link.
