China is helping Russia discreetly so that it won't be part of the trade war with the west. In return, Russia can give China some diplomatic backing. Putin acknowledging China's concerns regarding Ukraine is very helpful to promote China's position that China is neutral in the war, helping China's reputation in the west.I concluded the same.
Reading the leaves, it seems that China won't give the same treatment to Russia as it did before (basicaly treating it as an equal miltary/economic/diplomatic/sphere of influence power)
The next 6-12 months are going to be interesting, I very much think we will see further signs of this happening in the near future
I don't think China has ever seen post Soviet Russia as an equal. But trading some diplomatic help from Russia for economic aid to them makes sense
