The on-device encryption standard for iOS devices in India are no different from the ones anywhere else. If the OS is up to date, and the phone is locked with an unknown passcode, then Apple can’t get into it, in the U.S., India, anywhere.

Having said this: For now, it IS possible in India for Apple to obtain any data backed up in iCloud, if law enforcement follows whatever legal procedures are in place. Advantaged Data Protection (in which Apple “throws away” its copy of the encryption key), is not a feature that exists there yet. This is probably what they’re referring to here.
