Well in the unmanned arena, I don't think China is the leader..
With Japan having expertise in key areas including ownership of the largets module on the ISS(Kibo?).
They have also launched a range of probes to monitor solar activity etc..
They've got good experience on solar sail craft as well.
They've tried stuff like latching onto asteroids and all..
Japan' space doctrine is looking into cutting edge research rather than developing indigenous versions of already achieved space tech like indigneous
manned launch capability etc etc..
