Official: Nation a key climate contributor

China has made significant contributions to global climate action with its dramatic reductions of greenhouse gas emissions and efforts to reduce the cost of renewable energy.

As a developing country, however, it will not help rich countries close the gap in the level of support they had pledged to the Third World, a senior environmental official said.

Li Gao, director-general for climate change at the Ministry of Ecology and Environment, made the comment ahead of the United Nations climate change conference, slated for Dec 2 to 13 in Madrid, Spain.
