The basic story was that a consortium was buying farmland in California next to -- sort of next to, really -- an air force base. That story broke months ago when politicians started mouthing off about the "Chinese danger". Since then the concept has gained momentum and now we're not just seeing Reds Under the Beds but just about everywhere.
The problem is that the Chinese get everywhere. They've been opening businesses, investing and generally carrying on like good capitalists for 150 years or more and, furthermore, they keep doing so despite laws and purges designed to keep them in their place. Personally, I don't think they as a society care one way or another, all that matters is if they can make money out of whatever they're doing. (They do have a rather sly sense of humor, though, so I wouldn't put it past individuals to tweak the (paper) tiger's tail just for the fun of it.)
