Apparently, there is either a proposal or plan to equip FAB-250 UMPK Glide bombs with a propulsion system, which I would assume to be a simple rocket motor and not an actual engine. The claimed maximum range would be 100km (62.1 Miles)

A comparable bomb would be a JDAM-ER 500LB bomb, which RUSI claims has a maximum range of 80km (49.7 Miles) with a filling weight of 89kg (196lbs) compared to the FAB's 100kg (220.4lbs). So if the stats are correct the FAB beats out the JDAM-ER in both range and explosive power (can't speak to accuracy, but an extra 24lbs of explosive probably negates that just a little bit)
What I would be interested to see is a FAB-250 with one or more small jet engines, like those seen on the Iranian Shahed-238 or 358 Missile, the proposed Powered JDAM model which utilizes a 500lb Mark 82 munition is said to have a range of 345.2 miles (555km) and would be cheaper than even the cheapest cruise missile (though probably more expensive than a Shahed-131/136)
Link to Forbes Article (I converted the Nautical mile listings into standard units) about the proposed Powered JDAM, it also discusses that if the warhead was replaced with a fuel tank, the range could be extended to 805.5 Miles (1296.3km) and thus serve as a decoy.
I have no doubt that either Russia, China or Iran could manufacture an engine like the one suggested for the PJDAM, the TDI-J85 which produces up to 200lbs of thrust
