@Marketinfo; my contacts within China inform me that recovery therein is already well underway and approaching 70% of pre-Covid-19 operations. Still a very long way from 'normal' but certainly spluttering back into life.
In China new locally transmitted Covid-19 infections have been ZERO for the past four days indicating that the Draconian measures imposed have been effective. China's remaining threat is from expats and others from overseas arriving infected - the checking and quarantine regime being imposed is reported to be about as Draconian and effective as those applied throughout Hubei Province.
This is all good for Australia's economy - for both imports and exports and should greatly assist Australia's economic recovery.
As for the USA, ……….. fortunately Australia exports relatively little to it and could easily cancel the $300 billion in orders for new fighter planes and other useless equipment the government sources therein - economic problem $Solved!
