He maintains a relatively friendly relationship with Serbia, as they are fellow Orthodox allies.

He sometimes takes the side of Kosovo and Albania, who both despise Serbia.

A Countryball of the Balkan Peninsula. He finished the Yugoslav Wars early and is enjoying economic prosperity. His relations with other Balkan countries are relatively smooth, so fights involving Slovenia are rare. Having joined the EU and possessing an economy and society incomparable to other Balkan nations, he inwardly finds the former Yugoslav states—who do nothing but insult each other and fight all day—to be pathetic and wishes to escape the Balkans. Since Slovenia is barely hanging onto the edge of the peninsula, some Slovenians claim their country isn't even part of the Balkans.

He constantly says the word 'Shqip,' which other countries find stupid. Because his economy isn't great and he has a high Muslim population, he is sometimes not even treated as part of Europe.
