Transnistria Is a breakaway country which is only recognized by Russia&friends.

It is technically still considered Moldova by everyone else so it's not differentiated in documents from the EU and the likes.

It is not actually recognised by Russia either. It is in their best interest to maintain control over it, but officially recognise it as part of Moldova, so they can blackmail the entire country.
