Copper higher

Melbourne: The most-traded copper contract on the Shanghai Futures Exchange closed one percent higher at 52,070 yuan ($7,864.13) a tonne.

Three-month copper on the London Metal Exchange closed marginally down at $6,655, after gaining 1.5 percent in the previous session. Shanghai base metals futures were mostly higher on Tuesday amid signs that supply cuts linked to an environmental crackdown by Beijing will lead to greater import demand.

China issued an "action plan" in 2013 to reduce pollution caused by industrial plants, followed by provincial contracts and further policies. This included the so-called 2+26 Plan, which forces aluminium, steel and other industries across 28 cities to curtail production during the winter heating season from mid-November to March.
