A Chinese media quoted Mr Marius Kloppers CEO of BHP Billiton as saying that it would be difficult for Aluminum Corp of China to block the miner's takeover bid for its rival Rio Tinto Ltd.

In an interview with Chinese reporters in Melbourne, Mr Kloppers said that the 9% stake taken by Chinalco and Alcoa Inc would not hinder BHP's takeover plans. He said that "We hope to acquire 100% of Rio Tinto's shares, but our minimum offer is for a 50.1% stake. Therefore it will be difficult for a shareholder with a 9% stake to stop the deal."

Mr Kloppers dismissed claims by Mr Tom Albanese CEO of Rio Tinto that Rio Tinto is outperforming its predator. He said that "His claim that Rio Tinto's performance is 45% better than ours is unjustified.”

He added that "BHP Billiton has increased its offer, and Rio Tinto's shareholders should give this consideration."
