When Australia can export a product to China cheaper than China can produce it for themselves (even legitimately) China acts to protect China. Either imposing tariffs or providing state support for local industry.
So why is anyone outraged that anyone else would do the same ? Back in 2015 Australia was complaining about what Trump's administration is complaining about now :
Mr Calderon said China had saved itself about $US250 billion over recent years by flooding the aluminium market with supply and duly dragging down prices for the lightweight metal.That process forced many marginal aluminium smelters around the world, including in Australia, to be closed, and Mr Calderon said Australia's iron ore sector could endure a similar experience.www.smh.com.au/business/companies/chinas-iron-ore-tax-cut-puts-heat-on-australian-miners-20150409-1mh4pm.htmlI can't find reference now but back in about 2009 Australia imposed import tariffs on steel from everywhere. You could argue how does that make sense ? Australia is the largest exporter of iron ore, so how can doing anything to reduce demand for steel help iron ore exports ?
Who complained then ? Who even knew ? The tariffs came and went and nobody noticed, except those in the industry.
Which country doesn't impose tariffs on all sorts of imports ? When has this never occurred ? When has this been the biggest story of the year ?
So why does Trump suddenly get the medias attention on the subject ? Is it because he is Trump ?
Will it make much difference to anything ? Its been going on everywhere for the last 200 years so I doubt it. Blink here and there but not much else.
The endless printing of US dollars and China's refusal to float its currency in an endless race to devalue to make themselves more internationally competitive are probably infinitely bigger issues for the world economy and world trade than this beat-up storm in a teacup.
History will probably show the US having done nothing to stop China hoarding so much US treasury bonds and US cash for the last 30 years as the biggest mistake of the WWII to WWIII period. Trump's steel trade war will not even make a footnote in the English translation of the official world Wiki entry.
