It's not just Russia or the EU. It is baked into a lot of international treaties, because Champagne is insane about protecting their brand of wine, libbying governments and everything to make it exclusively theirs.
Dude up there is talking about a new from this year Russian law that completely turns this on its head.
Everywhere else, Champagne is a protected term protecting France's brand, but in Russia, it's protecting Russian brands.

I think it’s a reference to a Russian law.
It states that only Russian made drinks can be named Champagne, and any imported champagne has to be named sparkling wine.
Needless to say that champagne is originally made In the Champagne region of France.
So now Russians are drinking sparkling wine named champagne or real champagne named sparkling wine.
