It is "very interesting" in the sense that Snowden may have realised that strategically talking to Chinese press and leaking information that would be likely to be looked upon favorably by the Chinese government at this time would be likely to be beneficial to his chances of avoiding extradition in the future.

I'm not sure what you are trying to imply - the choice and timing of that particular leak would seem to be a logical choice once he'd chosen somewhere to go.
