According to some friends there, so far Airforce still have zero interests in this aircraft, and there is question whether this fighters could even obtain export lisences, even within AVIC, there are people who object export this fighters since it may contain sensitive techs.
Now AVIC try to persuade PLAN to order this fighter for their CVs, but it seems PLAN still want a open-competition between a navy version J-20 and this one, and the PLAN chief already made it clear that their future fighters on CV need to be capable of super-cruise, thats why in Paris airshow, the VP of AVIC bragged to the media that this FC-31 will be able to do super-cruise (initially they dont plan to add this feature to this fighter).
