You seriously think the Chinese government is going to stoop to K&R with random Americans?

The Chinese government is the last entity I'd be worried about with this kind of information (unless, of course, you live in China). Certain criminals in your own country are a much bigger concern.

Doubtful. But "the Chinese government" is comprised of individuals who might want to make a quick buck selling information on various markets. Perhaps to those certain criminals better positioned to take advantage of it.

This is similar to the concern some of us had over giving local government departments access to our full Opal card public transport travel histories here in Australia. Not all government employees are up to no good, but some are. Don't give them more than they need.
