Interesting to hear people who are complaining about the anti-China Olympic protesters use that phrase. Last time I heard it was when white South Africans were complaining about the sports boycotts in the 1980s. After making a political decision that only white people could play sports, they said, "keep politics out of sport." The thought is as absurd now as it was then.
Wouldn't "keep invasions out of international affairs" be a more useful slogan?
