Copper prices on the London Metal Exchange fell on Friday, weighed down by rising risks from trade tensions between Beijing and Washington, despite limited support from a weaker dollar.
The most actively traded copper futures contract in London fell 1.7% to $10,463 per ton, heading for a weekly loss of more than 0.2%.
The most actively traded copper contract on the Shanghai Futures Exchange fell 0.76% to close at 84,390 yuan (about $11,842) per ton, recording a weekly loss of 2.52%.
The pressure on the metal came after mutual warnings between the United States and China regarding rare earth exports, with Beijing accusing Washington of sowing global panic over its restrictions on rare earth exports.
On the other hand, the dollar's weakness limited the losses of the red metal, as the index - which measures the greenback's performance against a basket of six other major currencies - fell slightly by 0.15% to 98.19 points
