Jackson's suggestion of buying a bike in China exclusively for China is probably your best bet.
You can reduce the cost a little bit by getting a group together (see this
thread on HUBB doing something similar - sorry, don't know any ADV threads off the top of my head)... but whichever way you look at it, China on a foreign bike is expensive. Most people choose the detour option, but obviously this may interfere with your Everest plans.
