London copper hit its highest in almost two months on Monday after data showed China's factory output growth accelerated to eight-month highs in November, but
lingering worries that the euro zone may return to recession next year kept a lid on gains.
Signs of renewed vigour in China's factories have brightened the demand outlook for industrial metals, while glimmers of improvement from sectors of the U.S. economy, such as housing and jobs, are also acting to underpin prices. China is the world's top consumer of metals.

second-biggest economy is gaining momentum but optimism was trimmed by November exports that were well below market expectations.
Exports rose an anaemic 2.9 percent while imports were flat year-on-year.
