James Seng points out 6rooms, a Chinese clone of YouTube. Surfing further on the subject, the best information I could find was this post from Brian Curtis, especially his further discussion in the comments area.

Drives home the point that being first to market and well funded is not good enough…
Each time I’ve checked, YouTube was accesible in China. However, the censors can run hot and cold on certain sites. I am not in China at the moment to verify current status.
So a Chinese video market is emerging. 6rooms appears to have a bit over 100K videos up as of today - clearly a tiny fraction of YouTube's inventory. On the other hand, the Chinese market is large and they are actually ahead on some video applications, like peer-to-peer TV. So it will be interesting to see how this plays out over the next 12-18 months.
