Without knowing a single shred of details of PAKFA project, you have concluded that only contribution to PAKFA is funds, brilliant as expected.
No one is denying pakistani input, but similarly do not discount chinese and mikoyan input, Pakistan has not particularly had any design experience previous to this w.r.t product development of avionics, propulsion, material research, control systems and test equipment. Hence chinese responsibility would be to teach and smoothly transition pakistan into a lead role, similar license production have been done around the world before, with the exception that pakistan would share revenues with china if they find customers for export.
