But they must have more than just a few good reasons that makes them considering a chinese made engine.
The PAF's Block 52 Vipers still use Pratt & Whitney motors even though everyone else (except Israel I think) switched to GE. It's much easier and cheaper to maintain a powerplant from a manufacturer you're already using, rather than switching manufacturers late in the game. If a switch was made, all older blocks would be switched during overhaul, but for a long time it would mean maintaining 2 separate engine pipelines, which would raise the program cost. That's something the PAF would avoid if possible.
