That just means China has it harder and is more likely to fail. Access to global markets is a critical factor in growth of Japan, South Korea and China. USA controls that.

I think this fact is being severely understated, perhaps even denied by almost everyone in the west.
The way the US-China cold war has been playing out, the US and friends keeps closing doors only for China to go "Go right ahead, I don't have to play ball." and just succeed even harder on their own. Adding insult to injury is they then take that success and just wholesale buy the doors the US keeps closing.
A surefire way to lose Pax Americana is to become delusional that Pax Americana is winning when by all accounts it's losing and losing hard. I think this ship can still have its course corrected, because Pax Americana is better for us than Pax China, but not if we just keep up this kabuki theatre.
