I would be surprised if China was not a signatory od the international copyright law agreements: without that, works coming out of China would arguably be unprotected in the rest of the world too. As such, even if there might specific incompatible provisions in GPL, the nature of the license should be enforceable only if they cared. Though, to be honest, even in US and the "West", we haven't seen many cases where non-copyright-owner was able to score many GPL wins.
