Likely Xi of China has gotten some bad feedback from his foreign minister who reported back to him by now on his recent Europe trip.
So much so, Xi is actually getting ready himself to go to Russia now maybe by next week:

Xi will see first hand how little economically Russia under Putin can do for him by then. Russia under Putin will be isolated for some years for the biggest war since World War II that they brought to the nations.
On top of how wrong they are in their war, how they must cut ties with Putin as a country.
To ever see any trust from the East and West again in China.
China are a proxy to Russia in too many aspects for basic market conditions and variables to be amicable to the CCP State internationally for some time.
China are not big enough to live without America as an economy, either, for now.
