I think you have no idea how to develop a fighter.It will need several stages.Even the current T50 is not the final operational one,maybe they even wont look the same,the story happened in Cy27 DEVELOPMENT .Simply release some prototype pictures doesnt mean too much.You could only ask where is the Jxx PROTOTYPE? The answer is it will take off in one year. Again I already gave the post and link in this thread,please cheak it out by youself.
I dont want to repeat.But again please provide reliable links before post.Please offer links of the engine deal between Russia and China after 2005.Then we can talk something about it.And I think I am confused now.What would you want to prove from a Russia China arm deal? If you want to prove that we are highly dependent on Russia like you Indians,I might fail you.If you want to prove we cant produce moedern aircraft products as quality as Russia,I will fail you again.
