Hi,There is more than that - one could say how the Lavi itself had influences from the F-16.
But it isnt a Nesher to a Mirage V since the Chinese were thinking of a Canard configuration in the J-9. It is likely that refinements and design influences came from the IAI contacts in the 80s that resulted in the J-10.
Some Chinese refuse to believe that a PAF F-16 fuselage (allegedly the one struck by a boar) was carted off to China to be looked at for structural ideas.
But the J-10 is a “new “ aircraft in its overall design and not just a modification on the Lavi.
How about the pieces of the stealth helicopter at Abbotabad.
