LONDON, July 17 (Reuters) - Copper retreated from a two-weekhigh on Wednesday after U.S. President Donald Trump threatenedto impose further tariffs on China, a move which could dentdemand for metals.

Three-month copper CMCU3 on the London Metal Exchange(LME) closed 0.5% lower at $5,980 per tonne, after the metaltouched its highest since July 1 in the previous session.

Trump questioned China's failure to make good on what he sawas its promise to buy more U.S. agricultural goods, and saidWashington could impose tariffs on an additional $325 billionworth of Chinese goods if it needed to do so. urn:newsml:reuters.com:*:nW1N21900R

The year-long tariff standoff between the world's twolargest economies has sapped metals demand and helped dentgrowth in top consumer China.

"Trump said there is a long way before the trade deal issealed and he also spoke about extending tariffs, so that mightbe factor today," said BMO Capital Markets analyst ColinHamilton, adding that prices had "actually held up well despiteTrump's comments".

Trump's remarks came after the World Trade Organization(WTO) said the United States did not fully comply with itsruling and could face Chinese sanctions if it does not removecertain tariffs that break WTO rules. urn:newsml:reuters.com:*:nL8N24H53U
