LONDON, July 17 (Reuters) - Copper retreated from a two-week high on Wednesday after U.S. President Donald Trump threatened to impose further tariffs on China, a move which could dent demand for metals.
Three-month copper on the London Metal Exchange (LME) closed 0.5% lower at $5,980 per tonne, after the metal touched its highest since July 1 in the previous session.
Trump questioned China’s failure to make good on what he saw as its promise to buy more U.S. agricultural goods, and said Washington could impose tariffs on an additional $325 billion worth of Chinese goods if it needed to do so.
The year-long tariff standoff between the world’s two largest economies has sapped metals demand and helped dent growth in top consumer China.
“Trump said there is a long way before the trade deal is sealed and he also spoke about extending tariffs, so that might be factor today,” said BMO Capital Markets analyst Colin Hamilton, adding that prices had “actually held up well despite Trump’s comments”.
Trump’s remarks came after the World Trade Organization (WTO) said the United States did not fully comply with its ruling and could face Chinese sanctions if it does not remove certain tariffs that break WTO rules.
