State media reports say 11 workers have been killed in an accident at an aluminum refinery in central China.

The accident Wednesday at the Aluminum Corporation of China facility in the city of Zhengzhou occurred when equipment that the workers were dismantling collapsed on top of them.

The official Xinhua News Agency said another 8 were injured.

An official with Zhengzhou city government confirmed the death toll Thursday but declined to give details or her name.

The company, known as Chinalco, and other Chinese aluminum producers are among the bloated industries Washington and other trading partners complain are dumping exports too cheaply, hurting foreign competitors and threatening jobs.

China recently promised to rein in production of steel that is flooding global markets but made no commitments on aluminum.
