HANOI, May 27 (Reuters) - Copper prices advanced on Thursday, supported by supply threats in top producer Chile while a slower pace of earnings growth in leading consumer China’s industrial firms eased concerns of policy tightening.
Three-month copper on the London Metal Exchange rose 0.4% to $10,016 a tonne by 0710 GMT, while the most-traded July copper contract on the Shanghai Futures Exchange closed up 0.1% at 71,940 yuan ($11,278.34) a tonne.
Supply worries in Chile aided prices as miner BHP Group Ltd said it would take contingency measures after a labour union at its Escondida and Spence mines called for a strike.
“Copper received additional support perhaps due to the risk of strike action at BHP’s mine in Chile,” said ING analysts in a note.
Meanwhile, earnings at China’s industrial firms grew at a slower pace in April, calming worries over policy tightening in the country, while some positive signs on Sino-U.S. relations also boosted sentiment in the Chinese equities markets.
