Well, technically it is discrimination, but not racism. I.e. you can still hire a Japanese developer, and with a Chinese regime change you might be able to hire Chinese developers. However, federal law prohibits discrimination based on national origin. This is a touchy subject, but maybe this no longer makes sense? As burfrog pointed out, a Chinese employee living in America isn't free from Chinese control; the gov't will do bad things to his family if he gets a request for, say, information or access and doesn't comply. I'm hesitant to endorse allowing discrimination by national origin, but on the other hand, it doesn't make sense to allow the Chinese access to any kind of important data.
