BEIJING/SINGAPORE, May 17 (Reuters) - Copper prices on the London Metal Exchange are on track to fall for a fifth straight week, as deepening U.S.-China trade tensions sparked concerns about weak demand.
After a series of tariff hikes by the world’s two biggest economies, the United States on Thursday added Chinese telecom giant Huawei Technologies Co Ltd to a blacklist, making it extremely difficult for it to do business with U.S. firms.
On Friday, a front-page commentary in a major Chinese news outlet run by the ruling Communist Party described China’s determination to protect its national interests.
“The trade war can’t bring China down. It will only harden us to grow stronger,” the People’s Daily wrote.
Benchmark copper on the London Metal Exchange fell 1% to $6,041 a tonne at 0701 GMT, while aluminium edged down 0.6%, nickel fell 0.7%, zinc decreased 1% and lead edged 0.8% lower.
Despite easing on Friday, London aluminium is on track for its best week of gains since Feb. 22 as alumina refinery shutdowns in China raised production costs for the metal and sparked worries about supply shortages.
“The aluminium market remains tight. We estimate it was in a deficit of around 1 million tonnes in 2018, with ongoing supply issues likely to deepen this deficit this year,” ANZ said in a note, adding demand from China is showing signs of recovery.
