BEIJING/SINGAPORE, May 23 (Reuters) - Copper prices in both London and Shanghai fell to their multi-month lows on Thursday amid an unresolved Sino-U.S. trade tension and after Chinese President Xi Jinping warned of difficult times ahead.
The U.S. is considering Huawei-like sanctions on Chinese video surveillance firm Hikvision over the country’s treatment of its Uighur Muslim minority, the latest effort by the United States to crack down on Chinese companies as trade friction escalates.
