METALS-Copper slides on stronger dollar and demand concerns

(Updates as of 1710 GMT) By Polina Devitt LONDON, Nov 28 (Reuters) - Copper prices edged down on Thursday, weighed down by a stronger dollar, concern over global growth and demand in top metals consumer China. Three-month copper CMCU3 on the London Metal Exchange (LME) lost 0.2% to $9,002.50 a metric ton by 1710 GMT. The U.S. currency index .DXY edged higher -- reflecting strength that makes dollar-priced metals less attractive for buyers with other currencies -- in thin trading because of the U.S. Thanksgiving holiday. FRX/ Investors are still awaiting further developments after U.S. President-elect Donald Trump's pledges to impose a 25% tariff on all products from Mexico and Canada and an additional 10% tariff on goods from China when he takes office in January. "U.S. dollar strength, from the Trump effect, is holding everything back," said SP Angel analyst John Meyer. In a comment reminiscent of the trade war during Trump's first term, China criticised Trump's tariff vow on Thursday, saying that the imposition of "arbitrary tariffs on trading partners will not solve America's own problems". China's imports of scrap copper are set to slump, with some traders having already suspended buying from the United States, analysts said. Investors are focused on China's manufacturing purchasing managers' index (PMI) data due this week and the Chinese Politburo meeting in early December for further clarity on the outlook for China's economy. In other metals, LME zinc CMZN3 shed 2.5% to $3,051.50 a ton, retracing from its four-week high of $3,168 as LME data showed an increase to available stocks in LME-registered warehouses after the previous day's slump. "The scale of (zinc stocks) moves are not determined by any shift in demand or supply," said Alastair Munro at broker Marex, adding that the moves would be associated with warehouse rent factors. Aluminium CMAL3 edged up 0.1% to $2,597 a ton while lead CMPB3 was down 0.2% at $2,051.50. Tin CMSN3 rose 1.1% to $28,185 and nickel CMNI3 added 1.5% to $16,029.42.
