I use "uprising" in quotation marks to indicate that it is not a real internal uprising, but an attack by China
I really do not understand you.
"Attack by China" is full-scale war. Even in 10x10 square kilometers. First action of any counrty - to declare war and send regular army. If conflict continues or huge masses of Chinese forces arrive - nuclear strike imminent. There will be no "oh, sorry, we will give you siberia if you move out your forces from borders". This will be Third War. Maybe Last by coincidence.
