One or the other on either side would have to be completely fucking stupid to destroy the relationship Kruschev and Nehru set up.
Yeah,so IMHO Moscow will be the place where most important Asian mainland political meetings will be done, it will be the Vienna of Asia in the XXIth century.
Russia also has a lot of close ties with the likes of Vietnam, and both it and China benefit from an USA-free, prosperous Asian mainland.
IMO what will happen is this:
Russia and China split up influence in the former Stans, with the Russians having the majority of influence in Kazakhstan.
China gets access to resources and much bigger access to those markets for stuff like consumer goods.
Russia mediates between China and India and they eventually reach agreements, with the Chinese squeezing Pakistan to stop supporting anti-Indian forces, if they still have problems with AQ/Taliban, then their governmnet gets some aid from the Chechens and probably Iran.
Frankly, while it started off as a US ally, Pakistan has been moving more and more into China's orbit, and between China and Russia's allies in the area, it will be very easy to squeeze it until it starts behaving.
The Pakistani prime minister or whatever already had an interesting speech where he asks the West in response to their shenanigans adn attempts to get Pakistan to sanction Russia "...are we your slaves..."
They also see lots of weakness in the USA and I am willing to bet anything you want that the Chinese have some juicy revelations about 9/11 and Pakistan's involvement with the Taliban, which would preclude them becoming a US ally again.
Much of the Taliban involvement with the ISI for example is a matter of public record, and Osama did get killed in Pakistan.
TL;DR Pakistan is China and Russia's bitch, now.
MBS wants to pivot slightly to China and sell some oil in RMB because he is probably afraid of the China-Russia relationship and the new powerblock forming around it, he knows he will not have the same leverage over it as he has over the USA, and at the same time the USA has all those stupid green new deals and globalist virtue signalling going against it.
IMHO SA will stay mostly in the America-led block, while Russia will become a bigger player in the Asian emerging market block.
