jf17 was a good program and now PAF must joing turkish TAI TFX program to enhance its knowledge as Turkey has good know how of western technology ...
Problem with Turkey (and S. K.) is that they have never designed a brand new fighter jet before. And the first project will be a 5th gen jet? I do not doubt their capability, but the project has a lot more risks. Not saying any military fighter projects will be successful, if the risk is within the threshold of PAF it is certainly an option.
Compared to CAC FC-31, at least CAC designed J-10, JF-17, J-20 from start to finish. TAI can not match CAC on number of designers/researchers. And Turkey as a country can not match China in terms of industrial base.
