First things first, the image is a digitally created fake. A sophisticated one and whoever did it was quite skillful, but it is not real. There are however aerodynamic scale models of proposed J-14 variants that are real (but different than this picture) but those photos lack detail and are quite small.
Secondly, even if it were real, those are claiming it is a copy are obviouslly clueless. There is no other existing aircraft that even bears any remote similarities to the aircraft in the picture. The Su-47 was a heavily modified Su-27 airframe with forward swept wings. The Mig 144 project is only superficially similar in that both are twin engined planes featuring canards. Taken that to its natural conclusion, the aircraft in the picture would also be copy of the Gripen, Rafale, Eurofighter, the J-10, and any other aircraft with a canard that has ever flown.
And I don't know why people are still blaming Clinton for everything, p.s. It's been 6 years since he left office.
