Shanghai copper rises

Shanghai copper prices gained one percent on Tuesday and London rose, reversing light, currency-led losses from the previous session, as the dollar pared early gains and Rio Tinto reported a 9 percent fall in mined copper output.
Shanghai's benchmark third-month copper futures contract rose to a two-week high of 72,150 yuan a tonne, and eased to close at 72,000 yuan. The prospect of a firmer yuan also supported copper on expectations that China's increased purchasing power would offset rising prices.
