I've visited their local board here in the forum to see if there are some noise about the issue and so far I don't see any topics related to exchanges being shut down (either big or small) so my guess are this news about China is either fake or if it's real we are only talking about small exchanges here that's not even the main exchange of the Chinese people. You can check out their local board for yourselves and quickly translate it to English by right-clicking and then click "translate to English" to see what their topics.
