As I said we told Chinese engineers how to improve EW And radars of jf17 as well as software and hardware improvements and how can we tell that specifically what was these systems its classified
You're delusional in PDF there was a thread that's how many Pakistani engineers and scientists participated and how they improve the performance of jf17 in terms of electronics
Oh dude jf17 is design and develop to PAF specifications by China and our engineers were involved in the project if jf17 project is 100% Chinese than why we have 50% profit shares in this project? Think sensible and use a common sense
You forget to refer sir design and develop by France and its fly by wire system design develop by USA on their F-16 VISTA, its landing gear develop and design by Boeing etc etc
