This is actually an ill informed statement. AMCA can be deverloped completely indegeneously as all the buiding blocks are in advanced stages of developement : Kaveri 110-125 KN , stealth coating RAM, stleathy airframe shaping, serpentile air intake, 3D TVC, AESA radar, sensor fusion etc.
During the 90's when Su-30 mki contract was signed there was 0 % TOT and only licence manufacture. So obviously we decided to go for TOT in next collaboration with Russia which they are very reluctant to give.
The problem is IAF itself is not happy with PAK-FA as a semi stealth airframe is being passed on as Fifth gen even though it it just 4.75 gen and have suggested numerous changes. India has invested 295 million $ and a basic airframe design is reached which is exhibited in Aero-India 2013. We should withdraw from this project and develop this airframe as our indegeneous AHCA. With 6 billion $ investment which Russia is asking in ADA and HALwe can have multiple fifth gen fighters as well as stealth bombers and transport planes indegeneously. Better to go indegeneous route.
