stking - go to this sight and hold your pointer over Rare Earth and below you will see a listing of each of the rare earths, click on any one and a new page will up and to the right of the page you will see graphs detailing the pricing in domestic Chinese currency and pricing for the same product in US dollars for export FOB China.  There is a huge difference when converted to US dollars.
