China is ready to abandon its resistance to limits on its carbon emissions and wants to reach an international deal to fight global warming, the Guardian has learned.

According to Britain's climate change secretary, Ed Miliband, who met senior officials in Beijing this week, China is ready to "do business" with developed countries to reach an agreement to replace the Kyoto treaty.

Miliband said he was encouraged by the change in tone since late last year in the country that emits more greenhouse gases than any other. "I think they're up for a deal. I get the strong impression that they want an agreement,"
