Yes to some extent, but not much. The differences are:I have a feeling that this is becoming China's equivalent of the Su-35 deal.
Su-35 is good but not much extra good than what China already have. Good to have but alright not to have.
But JF-17 is all different to the potential JF-17 buyers, they have no alternatives (price-performance ratio) than JF-17 and they need something.
So I believe JF-17 has a way higher chance to get real deals than Su-35 to China.
