I've read several articles about lower copper prices on the back of slowing European, Japanese and American Economies and I've also read several articles about stronger copper prices on the back of ongoing mining problems and continued strength in the Chinese economy. LME copper inventories have turned and over the last week have seen a sizeable decline, I would suggest increased Chinese buying will support copper prices in the medium term.
