The only problem I see here is Russia doing the bidding on China's behalf. The joint statement has Russian influence all over it.
Russia got China a favourable statement from us in exchange for a favorable statement that we got from Russia during the NSA level meet on Afg earlier.
So 1) Russia failed to coerce China to be a part of NSA level meet and 2) is now firefighting on China's behalf.
It's evident Russia is losing the appetite needed to be a "superpower".
Also, we got some (new) lip service in exchange for the Olympic green signal.
