SINGAPORE, Aug 26 (Reuters) - China's copper futures prices fell to their lowest in three weeks, as demand prospects for base metals weakened following the latest escalation in the Sino-U.S. trade war.
U.S. President Donald Trump on Friday announced a 5% additional duty on $550 billion in targeted Chinese goods, hours after China unveiled retaliatory tariffs on $75 billion worth of U.S. products.
The most-traded copper contract on the Shanghai Futures Exchange fell for the fourth straight session, dropping as much as 1% to 45,830 yuan ($6,461.48) a tonne, its lowest since Aug. 5. It ended down 0.6% at the close.
China also said it will impose an extra 5% tariff on imports of copper scrap and aluminium scrap from the United States from Dec. 15, adding to the 25% levy on copper scrap from a previous round of duties.
"The escalation suggests uncertainty will continue to weigh on global trade, industrial production and investment, with no sign of a resolution," ANZ said in a note.
