Probably China is trying to show the way, even the technical way, on how to apply internet-wide censorship to other "freedom loving" countries. I think China may also be seeking some kind of official recognition of the fact they are not the only bad guys in town, that other countries are implementing the same measures, although with much less bad public reaction. If other countries will reference that Internet Draft in their (leaked) technical manuals or even participate in the discussion of it, China could much more easily justify its actions.
