I've never played a Chinese *designed* RPG (which I'd like to, I think it'd be interesting getting more non-Western designers/perspectives in games generally), but it's printing, minis, all that kind of stuff that many if not most Eur & US tabletop game manufacturers get done in China. I'm sure I have got boardgames made in China, don't think I've got any RPG books but then I don't actually own many of those (and the ones I have are mostly PDF). Smaller creators especially rely on the cheaper manufacturing China offers, I think. Of course, there are some pretty problematic reasons why Chinese manufacturing costs are lower, but given Eur/US manufacturing costs aren't dropping, it's tricky to see how smaller businesses can make things work with this change.
