On Russia maybe, but fighting with China in the future is inevitable.

Hardly. China is dependent on the US, directly and indirectly, for the
majority of its annual growth and over 20% of its entire economy. That's
not going to change much in the future as the two become more and more
intertwined. To even get into a position to battle America in Asia, much
less elsewhere, would require decades of spending the Chinese can't even
afford to build up to, and have no reason to. It won't be smooth sailing,
but China has vastly more reasons to remain friends if not allies with the
United States than to plunge itself back into the middle of last century and
ruin decades of economic building by trying to fight it.
