Rio Tinto says Chinalco deal situation "evolving"

CANBERRA (Reuters) - Global miner Rio Tinto's (RIO.L) (RIO.AX) planned $19.5 billion tie-up with China's Chinalco is an "evolving" deal, a Rio Tinto executive said on Tuesday.

Sam Walsh, head of Rio Tinto's iron ore business, told reporters on the sidelines of a conference that the miner would continue to listen to shareholder views on the deal.

The Rio Tinto-Chinalco faces opposition from some major Rio Tinto shareholders, who say that its terms are too favourable to Chinalco, and also from some Australian politicians who oppose the transaction on national-interest grounds.
