I think for all here with at least a bit of common sense it is clear since years, that the Lavi "influenced" the J-10's design and as such I do not want to overrate this image - esp. as proof for being a Lavi-clone, which is simply wrong – but however it is the first clear image that proofs that there were close contacts between CAC and IAI and that they even laid hands on the Lavi !
Quite interesting, it was taken somewhere in the 1980s some say even before the Lavi’s maiden flight in December 1986 ...

I too think that there were design inputs from Lavi. The assertion that J-10 is a simple clone of the Lavi design is ridiculous since they aren't designed for the same roles. Lavi is designed as a multi-role fighter with good air-to-air and ground-attack capabilities. As a result its supersonic performance is compromised to a certain extent (evident from the intake design). J-10 is designed as an airsuperiority/interceptor fighter and supersonic capabilities are emphasized (once again evident from intake design).
