The most-traded November copper contract on the Shanghai Futures Exchange (ShFE) declined 0.9% to 62,650 yuan ($8,702.60) per tonne.
Chinese President Xi Jinping reiterated the validity of China’s zero-covid policy, which includes lockdowns and movement curbs to prevent the spread of coronavirus, at the Communist Party Congress on Sunday.
A sharp increase in ShFE copper inventories on October 14 also dented sentiment. But tight supply, overall, of the metal in China continued to lend some support and cushion prices from steep falls.
Visible copper stocks in China, which includes inventories in Chinese bonded and ShFE warehouses, were 93,846 tonnes on October 14, edging up from a record low, but still, at low levels.
