The National Bureau of Statistics released data on Tuesday showing that China's primary aluminium production in April decreased by 1.2% compared with March, due to power cuts in the south-west China that limited metal production.
According to data released by the National Bureau of Statistics, China's primary aluminium output in April was 3.33 million mt, lower than the 3.37 million mt in March, but an increase of 0.8% over the same period last year.
Output growth has been constrained in China's fourth-biggest aluminium-producing province, Yunnan, where about 12% of China's aluminium capacity is located.
Yunnan, which relies heavily on hydropower, has asked aluminium producers to cut production since September due to limited rainfalls.
Statistics Bureau data also show that in the first four months of this year, China's primary aluminium output was 13.32 million mt, a year-on-year increase of 3.9%.
