I'd also prefer India to China; all I mean to say is that actively trying to make India more powerful as a counterweight to China is a dangerous policy with potentially troublesome longterm effects, as it has been in the past when nations helped others in an effort to provide a balance to other powers in the region. It serves to antagonize the power who loses out (in this case not just China, but also Pakistan, nominally ally of the US), and more often than not creates too radical a shift in balance which the various participants struggle to adjust to. Recent examples would be supporting Iraq against Iran or the support for the Mujahideen, though I'm in no way inferring the US is solely guilty of such practices.
