War with China over Sudan et al

[SadisticNature]

I think you missed the point. In a "war" scenario what good would it do China to "dump" any assets if no one is going to buy them?
Those that would support China do not have the assets to buy what they would "dump".

Actually the Chinese can set up economic warfare by dumping US debt quite easily. If they put the entirety of the US debt they own on the market the US currency will crash, making it harder for the US to import strategic resources like oil.

Since the US has already been using the strategic reserve to fuel the local economy this could lead to a situation where they have a lot of difficulty maintaining supplies of things like jet fuel and tank fuel. It would also be crushing for morale to see the dollar tank, and being faced with the economic consequences.

Nuclear powers don't end up outright at war because of the catastrophic consequences. But a little currency manipulation here, a little support for insurgents there...

That is a completely different situation that originally presented.
