China must have already long planned for this situation. But I guess we must wait and see just how bad Scott Morrison is willing to send Australia's economy down to until he gets rendered expendable. China has back up plans, Australia doesn't and once the are in a bad situation, they always try to get the USA to help but I get the feeling that this time, Scott Morrison, like Trump is committing political suicide and soon enough, should the corporations decide that they have harmed there profits enough, a real one. Once the USA gets sent in a depression (they can't print money forever), Australia will desperately try to reconnect to China, even getting rid of the elements that cause the problem in the first place and replaced with someone else stupid, when the government faced with enough unemployed that will riot from the lack of jobs thanks to Morrison. China's long term goals for Australia is happening (given that Victoria is still signed up with the belt and road) and it is going to take the global reset (right now all currencies are going down) and the stripping for the US world reserve currency status to show the world what China can do. Also note that Biden can ill afford a fight with China when there economy is in the dumps and heck he will sell china the steel they need thus Australia cucks itself again like an idiot for basically giving other countries more of a chance to sell. Come on, don't think that this iron ore threat means anything since there are lots of sellers right now and China has stockpiles but does Scott Morrison want to be the man to send Australia into a depression. Scott Morrison is a dead man walking at this point for causing this kind of trouble and if China's currency goes up in value, they might even buy up Australia and then basically dictate the terms upfront.
So no, this iron ore threat is like the whole HK thing, giving China what they want, basically killing themselves without shooting a bullet
