BEIJING -(Dow Jones)- The uncertainties of a tie-up between BHP Billiton (BHP) and Rio Tinto PLC (RTP) are "very big," said Luo Jianchuan, president of the Aluminum Corp. of China Ltd. (ACH), also known as Chalco.

Luo, in speaking to reporters on the sidelines of a local conference, said that he is "very worried" about the planned deal.

"This is a very big impact to us," Luo said.

Chalco is listed in Hong Kong and Shanghai and is the unit of Chinalco, China’s largest aluminum producer.

Rio Tinto last week received and rejected an approach from rival miner BHP Billiton, but talks are far from over and any successful merger of the two Australian mining giants would give it more power in global negotiations for iron ore, a raw material that is in high demand by China.
