Of course they do. But government bodies and other institutional bodies incarnated these standards organizations in order to better coordinate with one another, and decided and committed to defering to them a long time ago. Russia is a sovereign state, they can make any decision they want to, but they decided and agreed at some point to defer to this organization for a reason.

I think the commenter means that there isn’t a technical reason that GLONASS can’t be changed to not add leap seconds not that Russia doesn’t have to defer to an international body.
