Confident Rio Tinto commits to more expansions

Rio Tinto has sounded confidence in the resources market and says it'll be pushing ahead with its expansions.

The West Australian reports Rio Tinto iron ore CEO Sam Walsh said he expected China to grow at eight per cent and he hadn't seen some of the weakness hinted at by other miners.

Walsh said both in the short and long term iron ore was a "very robust business" and developing regions in other parts of Asia, the Middle East, and Brazil would also drive demand for resources in the future.

"Right now we're continuing to ship flat-out with very good production and we see that Australia is uniquely placed in relation to the product we offer but also the proximity to demand and that certainly puts us in the box seat," he said.

Walsh also dismissed suggestions Rio was depleting the world's resources too quickly, and said the company didn't see a "steel-starved world" in the future.

Last week BHP chairman Jacques Nasser said strike action by unions and other economic weakness was starting to hurt the company's bottom line.
