It seems the whole plan is ill conceived, and Indian govt must not decide in haste.
Reintroduction another species will augment the problem of conservation in India, Where there is no assessment of what the alien species will have in the native eco-system. Instead sustained international effort must be exerted on Iran to send the Asiatic cheetahs to India, where other big cats are thriving well.

Already the world has to grapple with the introduction of alien species in Hawaiian Islands and Mauritius, which is causing havoc to indigenous species.
So introducing alien species must be studied thoroughly before being undertaken.
If Iran shares the cheetah with other countries, it will only augment its effort to save the species from extinction.

Poor things don’t stand a chance
