The most-traded copper contract on the Shanghai Futures Exchange closed 0.8 percent lower at 44,580 yuan a tonne on Wednesday, easing after hitting its highest in over a year last week, with investors awaiting details of US President-elect Donald Trump's plans to boost infrastructure spending. Shanghai aluminium finished almost 4 percent lower at 13,600 yuan a tonne.
"There is some consolidation going on as investors are waiting for concrete plans from Trump on infrastructure spending," said Argonaut Securities analyst Helen Lau. "There is evidence to show improvement in China's demand, but the market is looking for more evidence before making further gains."
