I have a post up on the China Beat about race and espionage:
What’s interesting about Chinese espionage operations in the US, however, is that they appear to involve strong racial and nationalist overtones. The Soviet Union tended to appeal to ideology, or simply offer money or other types of benefits to its agents; China, it seems, is mainly going after overseas Chinese communities in its efforts to recruit spies.
While I'm at it, the Onion issue that parodies China -- which has gotten an unbelievable amount of attention -- includes an article that taps into this widespread notion of Chinese-Americans as potential spies. When the Onion features something, you know it's worth paying attention to.
