I've had conversations with many fellow REers, nothing to do with this site, who believe that NASA has been into space, and many of them doubt whether China really has.
This doesn't really prove anything with regards the "conspiracy" as a whole. It's more down to the fact that nobody really trusts China anyway. It's not as though America or the rest of the world doesn't make up any of what goes into the news- but at least if you don't like America (and live there) you can complain about it on the internet and not have to worry about being locked up
