According to Mining News Pro - Three-month copper on the London Metal Exchange ended 0.6 percent higher at $6,400 a tonne, although it finished the week more than 1 percent lower. The metal used in power and construction hit its lowest since March 28 on Thursday on a strong U.S. dollar and worries over the outlook for the global economy. "The dollar has been pretty strong lately which has been quite a drag, and that has now reversed a bit," Capital Economics analyst Ross Strachan said, adding that the market generally is "fairly quiet".

He said metals markets were mostly pricing in a resolution to a long-standing trade conflict between China and the United States as the world`s two largest economies prepare for talks. The dollar index eased versus a basket of six major currencies on Friday after weak U.S. inflation data eclipsed upbeat first-quarter figures. A weaker greenback makes dollar-denominated metals cheaper for buyers with other currencies.

"We believe prices will witness limited upside in the coming weeks unless a U.S.-China trade deal is finally struck, as concerns over global growth continue," Fitch Solutions said in a report.
