MA 60 (Modern Ark 60), is a passenger derivative of the AN 26, with the rear cargo door - a-la for roll-on, roll-off freight - removed.
Supposedly very underpowered, as the AN 26. The Russians fixed the power problems, and incorporated a APU and a lot of enhancements for hot and high operations, and renamed the plane as AN 32, whereas the Chinese decided the AN 26 was good enough and rebranded the AN 26 and you have the MA 60
