Aluminum Corp. of China, or Chinalco, is aware of differing opinions among Rio Tinto PLC (RTP) shareholders about its investment in the Anglo-Australian miner, but Chinalco President Xiong Weiping said the company hasn't received any request to renegotiate the deal.

Chinalco believes Rio's management will be able to explain the deal to its shareholders, said Xiong.

Earlier this month, Chinalco signed a US$19.5 billion investment deal with Rio Tinto PLC (RTP), marking China's biggest foreign investment.

The deal gives Chinalco minority stakes in a range of assets and convertible bonds that could ultimately give it an 18% stake in the miner.

The investment in Rio by China's biggest aluminum producer by output has raised concerns from Rio's shareholders and Australia's politicians, who deem the deal to be a threat to shareholders' and Australia's interests.
