Minsk-Belgrade with Belavia involves a stopover in Budapest and is operated by an Embraer 190 as well, so I don't think it would justify operating on its own.
Belgrade-Minsk is currently three times per week, two via Budapest and one non-stop.
I guess there is a market.
Neighbouring Georgia is much more tourist friendly and open.
