Alright, so now that Serbians are ready to give EU the high middle finger, I wonder if they'd be interested in buying JF-17 or J-10C. Traditionally, Serbians just don't have that much money to spend on their military equipment (hence HQ-22), but there really isn't a lot they can get if they piss off the Europeans. JF-17 would give them very good capability for a relatively low cost.
