Shanghai copper falls

The most-active September copper contract on the Shanghai Futures Exchange fell 0.6 percent to 70,330 yuan per tonne on Tuesday, after finishing nearly 1.3 percent higher previously. Chinese media reports about a possible rate rise in China this weekend, as well as a Moody's report saying the scale of problem loans at local governments in China may be much bigger than previously thought, also weighed on risk appetite and supported the dollar.
