BONN, June 2 (Xinhua) -- Clean energy was a vital area for the United States and China to work together in dealing with climate change, a high-level World Wildlife Fund (WWF) official told Xinhua Tuesday.

Both the United States and China realized clean energy was “the next market” after the IT revolution, which had deeply changed the world, said Keya Chatterjee, acting director of WWF's climate change program.
"China has made some investments in solar energy and wind energy just as the U.S.," she said. "You can see both countries moving into this direction."
Both countries were "a little bit neck and neck" in the field of clean energy, but "the seeds for cooperation have already been there," she said, adding the U.S. strongly desired cooperation with China.
As the two countries produced more than 40 percent of the world's CO2 (carbon dioxide) emissions, their cooperation in this area would be critical for the world, especially for the small island countries and high mountain states that faced a real threat from climate change, Chatterjee said.
"The potential and room for the U.S. and China to collaborate in this area are very wide," she said.
Chatterjee said she had found more constructive signals during the UN climate talks in Bonn, which started on Monday, on the issue of fulfilling the promise of last December's Copenhagen climate summit than before.
At the contentious Copenhagen conference, developed countries promised to raise 30 billion U.S. dollars to help developing countries cope with climate change. It's also one of the key issues at the Bonn session, which has attracted 4,500 participants from 182 countries.
Chatterjee said financing was most definitely a precondition for mutual trust between developing countries and developed countries.
