The series mentioned other countries, but even those were on the same continent for the most part, with the possible exception of Ul, Lyon and Gray's homeland, which maybe be on another continent, but if I remember correctly it was never confirmed.

As far as mention of mages in those contries go, we have nothing except for Ul and she, according to herself, was less powerful than "tons of" mages in Fiore.
