According to reports, Aluminum Corp of China , known as Chalco, said late on Wednesday it had stopped production at an aluminium smelting plant in eastern China’s Shandong province, citing high electricity costs.

In a statement to the Shanghai and Hong Kong stock exchanges, Chalco said it was implementing “flexible production” on all 200,000 tonnes per year of capacity at its Shandong Huayu facility due to “high electricity prices, regional environmental protection policies, market environment and other factors.”
