Copper futures ended lower on Monday due to worries about demand in world’s top consumer China after China's state planner the National Development and Reform Commission (NDRC) has said it will continue to release copper and other industrial metals from its reserves in batches. Further, concerns over spread of the delta variant and surging American currency also weighed on red metal prices.
