Word is out there from semi-credible sources that Bangladesh has purchased 14 J-10Bs (although I think the author meant J-10Cs).
Would China be comfortable giving AESA technology to Bangladesh when they've only very recently started equipping AESA J-10Cs themselves? Additionally, the FC-20 model displayed in Singapore a year ago was only a J-10A, not even PESA. To suggest that China went from "we'll allow J-10A exports" to "we'll allow J-10C exports" in less than a year seems very unusual to me.
