In the long run, UNSC will be reformed because the present one can't reflect the real global hierarchy any longer.
Eventually, China will welcome India to be included in a reformed UNSC because that accords to Chinese pursuit of a multipolar world. China will benefit more from a balanced multipolar world than a world controlled by America.
I think India should be more wary of US, because US has always opposed the idea of a multipolar world and refused to share the power with emerging countries. People can't rule out the possibility that Obama may have been paying lip services.
