BEIJING, Jan 25 (Reuters) - London copper edged higher on Friday as support from a weaker dollar saw the metal claw back the previous session's losses, although uncertainty over the progress in U.S.-China trade talks capped the upside. Copper remained on course to shed 1.6 percent this week on fears China's slowing economy will hurt demand. That would mark its steepest weekly drop since the week ended Dec. 21. On the supply side, Freeport McMoRan Inc, the world's second-largest copper miner, forecast on Thursday a drop in 2019 production. An Indonesian official said earlier this month that Freeport's Grasberg mine would produce around 1.2 million tonnes of copper concentrate this year, compared to 2.1 million tonnes in 2018, as operations move from open pit to underground mining. Grasberg's output is expected to double between 2019 and 2021, Freeport CEO Richard Adkerson said. "As long as global GDP growth exceeds 1 percent this year and 2 percent (per year) on average thereafter, the market should go into a meaningful deficit with rising prices," Jefferies analyst Christopher LaFemina wrote in a note.
