Contemplating the possibility, probably. Actually expecting it to happen? No.
Neither the US nor China want to see war, because it would be economically devastating to both countries. If you think $4.50/gallon gas was bad, imagine the impact an overnight general doubling of the price of nearly everything sold by Wal Mart would have on US consumers... or the effect an equally instant loss of both the US and EU as export markets would have on China's economy. I'm not even going to mention the effect skyrocketing prices for computer components would have on Microsoft and the rest of America's computer industry... I still remember what happened after the earthquake in Taiwan caused ram prices to double, double, then double again... and remain that way for years.
Let's take the most obvious case -- Taiwan declaring independence from China. Wanna know what the US would do? Exactly what we've already assured China we would... scold Taiwan like a naughty child, firmly announce (via the UN) that they aren't being recognized as an independent country, maybe look the other way while the PLA sends a fighter jet or two to drop a couple of conventional bombs somewhere symbolic, but largely uninhabited within Taiwan, and let Taiwan know that if they don't retract the declaration, the US and EU will be imposing sanctions against them until they come to their senses.
IMHO, the biggest risk from China is that it might do something shortsighted and stupid, like shoot missiles at somebody's satellites, and create enough space junk to render commercial satellites almost completely non-viable for the next thousand years. If any satellite in orbit had an 80% chance of being destroyed by a collision with space junk, it would pretty much be the end of satellites as general-purpose commercial communication devices. There would still be a few weather satellites, and a bunch of military satellites, but we could all kiss DirecTV, Dish Network, and Sirius goodbye.
