They are also "too big to fall" - any economic sanctions against China would hurt the West equally (if not more) than them. China produces half of everything you buy.
I think the pain in the West would be relatively short-term while they are rebuilding manufacturing capacity. Globalization has hurt a lot of workers in the West so it may actually positive for them. China on the other hand would have nobody to sell their stuff to.
They also import a ton of food, ore, oil, and LNG, so who knows how that dependence plays out.
