I just confirmed through my buddies in China that soldiers are at the production facilities, border crossings and shipment points preventing metals from being exported out of China. Magnesium and Zinc seemed to be especially targeted. Mandatory checks are being done by soldiers and all metals are being stopped. The border is completely sealed and they will not let certain metals out of the country.
