The international climate negotiations have gone through 20 years of ups and downs，so far failed to reach an international emissions treaty acceptable to all parties. Reasons are as follows，first，the complexity of the climate issue，involving scientific，political and economic aspects；second is geo-political and economic pattern of rapid evolution，mainly in developing countries rapid rise. China’s international economic position is more and more important in Copenhagen climate agreement negotiations，and China is a focus in various parties. Considering that the international community，especially the commitment of developed countries and the international community’s expectations to China，China current energy-saving emission reduction actions should be able to take the initiative to promote the Copenhagen process，but should on the basis of China’s national conditions and make rational commitments. After Copenhagen，the challenge is more severe；it must put forward a solution as soon as possible，to gain the initiative in the future.
