This article emphasises the impact on Putin's Russia. I believe the impact is as great, if not greater, on Xi's China.
The CSTO is largely made up of Silk Road nations - nations that have no particular historical affinity to either Han China or Muscovite Russia.
The western end of the Silk Road is "anchored" by Chechenya, Dagestan, Georgia, Azerbaijan, Armenia, Turkey and Ukraine.
The eastern end is likewise anchored by the Koreas and Japan.
