There were race riots in Algeria recently, Arab on Chinese. The interesting thing was that neither the Chinese or Algerian governments made a big deal about it. http://news.bbc.co.uk/2/hi/africa/8184499.stm (h/t No Pasaran http://no-pasaran.blogspot.com/)
If this had occurred in America, the blame whitey crowd would have been out in force and the Chinese government would have brought its full diplomatic leverage to bear on the U.S. government to prosecute the white rioters. Just as it did when a Customs and Border Protection Officer pepper sprayed and arrested a Chinese national who was attempting to escape arrest for alien smuggling. (Sorry no link) In this case the Chinese government demand and obtained prosecution of the officer for civil rights violations for using justified force in the arrest. Fortunately the officer was found not guilty, but other governments have previously demanded prosecution of Americans law enforcement like Border Patrol Agents were prosecuted at the demand of the Mexican government.
However, China, so once concerned about one of their citizens in the U.S. who was arrested for alien smuggling, suddenly is not concerned about dozens of Chinese citizens injured in a race riot.
"A diplomat at the Chinese embassy said he hoped Algerian authorities would look into the fighting but added that it would not affect relations between the two countries.
'Our friendship with Algeria is strong and this event is nothing in comparison with the links between our two countries,' Ling Jun said."
Seems like a double standard that the American government accedes to.
