SINGAPORE, Aug 19 (Reuters) - Copper prices advanced on Monday as China announced new measures to support its economy amid a damaging trade war with the United States, potentially improving demand for the red metal.
China's central bank over the weekend unveiled a key interest rate reform in a bid to help steer borrowing costs lower for companies.
Three-month copper on the London Metal Exchange rose 0.4% to $5,764 a tonne by 0410 GMT, while the most-traded copper contract on the Shanghai Futures Exchange edged up 0.2% to 46,510 yuan ($6,602.22) a tonne.
However, the metal's rise was capped by weak data that showed the Chinese economy continues to be hurt by an ongoing trade war with the United States, while a trade deal is not yet in sight.
