OP don't even mention where he heard such information, so i have some doubt. However, even if true, it's likely they (people of china) can't have control over their coin.
That too, we also don't know if the source is a credible one and we know that China is suppressing information about them so we can't be entirely sure. If that is the case then too bad for the people because they can't enjoy the benefits that bitcoin provides.
