The Western Confucian: A Tale of Two Race Riots:
I see very little difference between the Lhasa Riots of 2008 and the Los Angeles Riots of 1992. Both arose out of real or perceived systemic injustice. Both targeted entrepreneurial peoples known as Han, Chinese (漢) on the one hand and Koreans (韓) on the other. Both left dozens dead. Both the Chinese and American authorities were perhaps not blameless in the attempts to restore order.
But the reactions to both race riots have been quite different. While there were some people who blamed the events of 1992 on American injustice and racism, there was nowhere near the rabid anti-Chinese sentiment one sees on display today. I don't recall any anti-American demonstrations being held in foreign cities or foreign governments censuring the United States.
Another parallel that springs to mind is Kristallnacht that took place in Germany in 1938. The main difference, however, is that Kristallnacht was government sponsored, while those mentioned by the Western Confuctian were not.
