If China comes in big it would mean the end of their territorial ambitions to the east [Taiwan, South China Sea] for a long time. They know that and so would do their best to stay out unless it all spills over into their present territory. When the planes and shells start flying, though, the national assembly might panic and commit to something they shouldn't. Time to be cool and collected.

Yes. They are much more concerned about Taiwan, control of the South China Sea, trade with the Pacific Nations (including the USA). They would not risk these objectives for "political hay" in the 'steppes and 'stans.
