Chinese Premier Wen Jiabao's attendance at the Copenhagen conference will inject a new momentum into international climate change talks, Deputy Foreign Minister Wang Guangya said Thursday.

"Wen's trip to Copenhagen will inject a new momentum into the climate change talks and exert positive and important impacts for future international cooperation," Wang told a press conference on Thursday.

The UN Climate Change Conference, which opened Monday in Copenhagen, gathered representatives from 192 countries and aimed at mapping out a plan to combat climate change for a period from 2012 to 2020.

At the invitation of Danish Prime Minister Lars Lokke Rasmussen, Wen will attend the talks that will run through Dec. 18.

Wang gave no schedule for Wen's trip to the Danish capital, but said premier would deliver an important speech, outlining the country's efforts to deal with climate change and to promote international cooperation.

Wen is also scheduled to meet with foreign leaders on the sidelines of the talks, Wang said, without specifying those leaders.

"Wen's attendance spells out the Chinese government's attention and positive stance on climate change and signals the country's determination, confidence and political willingness to combat global climate change," Wang said.

Wang highlighted measures the Chinese government had taken to tackle climate change, including the country's latest pledge to cut carbon dioxide emissions per unit of gross domestic product by 40 to 45 percent by 2020 compared with levels in 2005.

China announced last month it would develop renewable and nuclear energies to increase the proportion of non-fossil-fuel power in China's total primary energy consumption to around 15 percent by 2020 from 9 percent by 2008.
