Japan's decision vexes Cancun meeting

CANCUN, Mexico - China's chief climate change negotiator, two days into the two-week conference, voiced his frustration over Japan's forceful rejection of an extension to the gas restrictions set under the Kyoto Protocol, calling the decision "not a very welcomed position".

Su Wei, head of the climate change department of China's National Development and Reform Commission, also called on all participating countries to work together. Otherwise, he said, "we all draw back".

"The (Kyoto Protocol) is a very important conventional tool to help achieve optimistic objectives in climate change," he said.
