I'm not a consipracy theorist, but feel strongly that China is not forthright or honest when disclosing their needs for copper and other metals. They are not governed by the same laws as disclosure as we are in North America. I think they regularly manipulate the price of copper so they can buy large amounts at a discount.

China has said many times over the past year or two that there is a slow-down, or that demand for copper is weaning. The price of copper goes down. Then, China continues to buy copper, contrary to their statements. I'm sure the same thing happens with gold and other metals.
