Yunnan copper deal

THE Aluminum Corp of China, parent of the nation's biggest producer of the metal, has agreed to buy a 49-percent stake in Yunnan Copper Group for an undisclosed sum to expand further into base metal production.

Aluminum Corp will use the copper producer's resources to help develop its domestic and overseas copper assets, Yunnan Copper Industry Co, a publicly traded unit of Yunnan Copper Group, said yesterday in a statement. Yunnan Copper Industry is China's third-largest producer.
