Seems to me like China is trying to distance themselves from North Korea while not throwing them overboard completly.
But who does China think did it?
[Obligatory "Tommorow Never Dies" joke here].
I think they're playing dumb. There is a Russian investigation going out to South Korea though, so it will be interesting to see what happens if they agree with the first investigation.
Also here's an interesting piece by B.R Myers on how the South Koreans are really not interested in a conflict there.
