In Russia, as far as I know (and I have close and active sources of information), there is no change in freedom to travel unless you are under a formal mobilization order or are already serving in the military. Many Russian men regularly travel abroad for any reason at all. There is no special or extra-constitutional regime in place.
I think you might be mixing up the policy with Ukraine’s.

No its not a mix up. Its a Xi Jinping policy.
