Plagued by the strength of the US dollar, most base metals retreated on Wednesday, with copper falling from a one-month high.

Le cuivre à trois mois à la Bourse des métaux de Londres (LME) a gliss é by 0.5% à 9,112 dollars per ton to 03:37 GMT. Producer prices in the United States rose less than expected in December, as rising goods costs were partially offset by stable prices for services, which suggests that inflation is still on a downward trend, but does not change the view that the Federal Reserve would not cut rates until second half of the year.

SHFE's most active copper contract was down 0.2% at 75,150 yuan ($10,250.15) per ton at the close of the morning trading session in Asia.
