Copper up

Manila : London copper edged higher on Wednesday after sliding more than 1 percent in the previous session, but gains were capped with investors cautious after the United States pulled out of an international nuclear deal with Iran.

U.S. President Donald Trump said he would reimpose U.S. economic sanctions on Iran to undermine "a horrible one-sided deal that should have never, ever been made".

Firm copper demand in top user China also spurred the price of the metal higher, although a lack of supply disruptions suggests the market is not as tight as many had expected, said Helen Lau, analyst at Argonaut Securities in Hong Kong.

"There´s no strong case for a big price recovery in copper given better than expected supply, especially in South America," said Lau.

Three-month copper on the London Metal Exchange was up 0.9 percent at $6,802.50 a tonne as of 0249 GMT.
