I’ve read several times in Russian forums that its confederal capital was supposed to be in Minsk But never could find a source for it, anyone got more information?
From what I can find of the New Union Treaty's text (in English) it says the capital was to be in Moscow (Article 21): https://soviethistory.msu.edu/1991-...ne-plus-one-agreement-texts/new-union-treaty/
Perhaps later this was changed to Minsk, but it could also be that this is in reference to the CIS headquarters being in Minsk and perhaps any new confederation proposed after that having its proposed capital in Minsk as well...
