If it is true than I don't think Russia will sell them because a pressure from china for such a powerfully bomber and aggressive position it gives to IAF
One thing I know about tu 160
White Swan' is that, China asking for
White Swan' for a longtime, and Russia only offering tu22.
I don't think Russia considering selling
White Swan for anyone, if somehow India able to brought some, its going to cost a lot, 250~200 mil$ or more a piece with low availability rate.
Ex- says lots of things, don't take everything seriously.
IAF consider rafale/aew/mta/drones etc in place of tu 160, which rarely flies due spares shortage.
