The moment they signed off for FC-1, they had no alternatives available for themselves with J-10 being in initial stages going through tweaks. Thanks to flurry of developments in Chinese aviation industry, now PLAAF has more choice and altogather different operational requirements. JFT still fitts well into PAF's operational requirements. And let me tell you, even if exports are made, the export varients will be significantly different from JFT. PAF has histroically seen its procurment decisions independent from PLAAF. It didn't acquire J-7s because PLAAF had it flying but rather optimized to meet her own requirements. The same is the case with JFT. If it were a so called "cheap and inferior" aircraft it would not have been aclaimed and promoted by international defence media. Lastly as I said over and over again, JFT/FC-1 is a JV between CAC and PAF not PLAAF and PAF. So since the PLAAF did not contribute development costs, the cost of JFT for them would not be the same as for PAF. PLAAF funded J-10 and other projects, which means that Price tag of J-10/J-11 for PLAAF would be more attractive than even JFT, not to forget they can spend more.
