Also what they did for copper was outright dodgy, they caused copper smelters to shut down around the world simply put the chinese government offered to pay $1000 more for copper concentrate than the contained copper in ore so if back then you buy 3tons of 33% copper ore and it makes 1 tonne of copper and if copper per ton was worth say $3k normally factories would buy the ore for 90 to 95% of the contained copper in ore.. so you had 5 to 10% margin for profit to refine it. What China did was offer $4k for ore which once refined would only be worth 3k so bonus $1k for raw product sent to them. Once contracts lapsed no one could compete or get ore at sane pricing why would anyone pay 4k for ore that can make a 3k product! China will and does this kind of business once smelters closed China controlled copper and it went through the roof - clever but sneaky and manipulative long term strategies....interesting times ahead indeed...
