I have reservations about this, why would China want to hand over years of R&D over to Indian hands? Especially when India has an operational Heli program of their own and can easily integrate Chinese R&D into their program. Secondly, the Chinese know that India will not agree to accept Chinese control over any aspect of their defence production because in case India has to deploy them against Pakistan, Sri Lanka, Bangladesh (all Chinese allies), China can easily discontinue supply of parts and service. That would leave India with a fleet that just looks good on the tarmac, not in the air.
