I'm sure the PLAAF is still not satisfied with their current inventory of Y-20s and plans to purchase at least a few dozen more. This program was always prioritized to provide the Chinese military with an adequate heavy transport, not to sell to other countries like the JF-17. Also, since the WS-20 is very close to induction with the Y-20, I'm sure the PLAAF would wait for the domestic engine before any export considerations ... esp considering the inadequate capabilities of the D-30KP2. I hope this answers your question ... otherwise, you're just arguing in circles.
