The guy being interviewed is retired Air Commodore Khalid Chishti.
He has his own YouTube channel and normally claims he has exclusive access to Pakistan Air Force, therefore, to some he's considered as an unofficial PAF mouthpiece.
On J-35, he says the following:
- PLAAF has not inducted J-35 yet.
- J-35 is going through the last stage of trial and evaluation of its production (choice of engines and missiles are being finalised).
- Pakistan has not agreed to purchase any J-35s while the aircraft is going through trials and evaluations.
- Pakistan will consider J-35 for purchase once all the different weapons have gone through test-firing and it's actual performance is reviewed against what is claimed to be it's performance.
- Pakistan is currently at wait and see stage
