SINGAPORE, Aug 7 (Reuters) - Copper prices slid for a second session on Tuesday as an escalating trade war between Washington and Beijing raised concerns over demand in top industrial metals consumer China.
Three-month copper on the London Metal Exchange gave up 0.3 percent to $6,112.50 a tonne by 0153 GMT and the most-traded copper contract on the Shanghai Futures Exchange lost 0.3 percent to 49,220 yuan ($7,173.78) a tonne.
On Friday China unveiled tariffs on 5,207 items imported from the United States, with the extra levies ranging from 5 percent to 25 percent, which analysts say could eventually undermine growth.
However, even though items earmarked for the 25 percent tariff include copper ore and concentrates, the quantities involved are not significant for China, analysts at ING said in a note.
