Chinese Premier Wen Jiabao said Monday that China was willing to work with other nations to bring about a "fair, reasonable and realizable" outcome of next month's UN climate change conference in Copenhagen.

Wen made the remarks during the 12th China-EU Summit, which opened in the east China city of Nanjing Monday, saying China would work to move the Copenhagen conference in the right direction.

The United Nations Framework Convention on Climate Change and the Kyoto Protocol were the major channels and the basic legal framework for nations to tackle climate change, Wen said.

The principle of "common but differentiated responsibilities" was the key to successful negotiations, and therefore should be observed, Wen said.

Wen hoped the European Union would show greater political willingness to take the lead in cutting carbon intensity and supporting calls from developing countries for funds and technology.

"China has taken a series of measures to deal with climate change, which has brought about remarkable effects," Wen said.

The government announced last week that it would curb emissions per unit of gross domestic product by between 40 and 45 percent from the 2005 levels by 2020.

"This is a great contribution we made to tackle climate change, and the promise on emissions targets is a serious and solemn one," Wen said.

The target was made on the basis of scientific research and conformed to reality, Wen said.

Wen will attend the climate summit in Copenhagen next month.
