Older flights prior to March 2022 still use Russian airspace. I guess this is best
compromise for China & USA.

And Chinese airlines won't be forced to change what they're currently doing, since only new frequencies are affected.

I think something like this is actually in the "zone of possible agreement" for both sides. However, I don't see an agreement being reached anytime soon due to the current state of US-China relations.
