Are there any formal attempts to create formal diplomatic ties by the various Russian states?
I know that "officially" the Russian Federation (the Russian state located in Kaliningrad) is the successor state to the USSR, holds its seat in the UN, and mosr importantly is in the UN Security Council, but that doesn't stop the others from trying to cement their own claims and reach out.
With the amount of cooperation seen during the attack from North Korea, it seems like Japan and South Korea would be willing to formalize relations with the Far Eastern Kingdom.
Communist states (except for China due to its own policies regarding Taiwan) and allies of the former Soviet Union are likely to recognize the Russian Soviet Republic, but with the fall of the Castro regime in Cuba there aren't any that could meaningfully send aid.
For all we know, the Russian National State could be sending diplomats to various countries that lean right-wing or are currently run by military dictatorships.
Edit: I'm afraid if one of these groups get desperate and start trading nuclear and chemical weapons for aid, military support, or diplomatic recognition.
We've already seen them take remaining minority ethnic groups hostage and "sell them off" for aid.
