The pictures show a very close, near carbon copy match.

I'd think it was photoshopped, but they've mastered the art of copy and it's not unlike what the Chinese do with the Russian designs they build.

Perhaps they didn't have enough motor for a single, at least not yet, or maybe they prefer a twin engine and went with two, smaller but proven engines instead.

Either way, they've saved a bunch on engineering and caught up quickly. The electronics and software should be relatively easy.

What do you think is holding back the F-35 from entering IOC? Software and electronics.

The evolutionary starting point for both the J-31 and the F-35 is the YF-22. The J-31 does adopt some cues from the F-35, such as the intakes, but otherwise it's a very close copy of ATF contender.
