Its doesnt matter my friend, i mean if you are out to troll or you are having some false sense of pride from the success of JF17 at least practice some common sense in doing so.
Chinese engineers have sort assistance from Amercians, Russian and Ukraine. Thus they are able to achieve what they are, today.
Seriously, our chinese audience must be bursting into laughter if this ever got translated into mandarin. Its a 5th generation plane for fug sake. The amount of trumpet blowing is comparable to the Indians claiming that LCA is the best in the entire universe.
Having a glorify assembly plant is nothing.
Having a know how and know why is the key.
Your mentality is no different from the Indians thinking that they can build whatever they want as long as they import the entire assembly line be it from the russians, french, amercians.
Please dont ever let the chinese know i bet they will be laughing their @ss off.
