Big dose of reality, page-86

"Holy "mouth's of babies", I seriously cannot believe the naivety, check your source"

So the problem is with my source and not with your understanding of things, as usually.

From the internet.

China has scrapped its export quotas for rare earths, minerals used in mobile phones and other high-tech products, after losing a World Trade Organisation case brought by Washington and other trading partners over controls that alarmed global technology producers.

The change was included in the Ministry of Commerce’s trade guidelines for 2015 but there was no separate announcement. Under the new guidelines, rare earths will require an export licence but the amount that can be sold abroad will no longer be covered by a quota.

Voila, the source for the discrepancy. Haven't you learned from Econ101 that when you have two markets (the Chinese internal one) and (the international one based I suppose in NY ) and arbitration becomes impossible they can easily get out of sinc, specially in a case where supply to one of them is severely restrict by gov regulations.

Sorry to say it, but this is elementary.
