The Australian government would be open to negotiations with big business over plans for carbon trading, Prime Minister Kevin Rudd said on Wednesday, after industry complaints about government proposals.

But Rudd warned business that carbon trading, needed to help Australia cut its greenhouse gas emissions, could not be done without some cost on industry.
"It will never happen cost free. It is not a cost-free business," Rudd told the National Press Club on Wednesday.

Canada plans to boost its spending on mapping Arctic energy and mineral resources, in order to encourage development and defend Canadian sovereignty in the far North.

The government will spend C$100 million (US$95 million) over five years, building on a plan earlier this year to spend C$34 million over two years, Prime Minister Stephen Harper said on Tuesday as he prepared to kick off a three-day trip to the region.
