China's medium-term outlook is pretty hopeless, let alone the long term. They are deep into a depopulation bomb, private capital is all but exhausted, so Xi falls back on their "tried and true" - printing money? Their labour force is increasingly uncompetitive with other Asian countries, so the marketplace of cheap, shitty goods is slipping through their hands, as well.
With literally millions of unsold, uninhabitable living spaces, and economic policies that seem to wander around at whim, they can't even scare most countries with what seems like an outsized military. They have no way to project anything but limited power abroad.
A picket line of destroyers or other ships of war parked in the Indian Basin to stop Chinese commerce in the case of a truly belligerent China, and they would be starving in the dark in 6 months. Between China and Russian, there is a very real potential of being dragged into a worldwide depression. China has a beyond critical lack of fuel, industrial inputs, food and even the inputs needed to grow food at scale.
As if we shouldn't have recognized it all along, we in North America are blessed beyond belief, especially if we can build out the manufacturing capability to be self-sustaining in time. If any region in the world can weather this potential catastrophe relatively unscathed, or at least without deep, mortal wounds, it's this one.
