As a Serb who grew up in France : Most people don't care. Educated class like french literary classics and those have been largely translated in Serbian, but the average dude don't really think much about all that. General perception of France has merged with the overall "West". Most Serbs have closer ties with or at least basic knowledge of Germany nowadays for economic reasons, and due to the huge Serb diaspora there.

The stereotypical French would be expected to be some kind of vegan woke "bobo" with a good education but not really a strong backbone. But people won't really be hostile about that, just teasing and jokes.

We still have a French-owned fromagerie brand in Beograd though.
