Are you sure about the long-term consequences of supporting that move against the US - especially when China appears to want to be less free? The last thing the United States needs now is one less ally.
Perhaps Australia needs to be reminded that the consequences of appeasement apply to China. That, and the same lesson should be taught within the United States. Then keep on teaching that lesson until the PRC respects the individual enough to tolerate Tiananmen Square.
If they say “just business”, inform them about how Danegeld doesn’t work. Worst case, treat China like Iran.
I am not sure about anything. I just understand how one might react to American fiscal and monetary foolishness.
