Chinese Premier Wen Jiabao has reiterated his country's support for the Copenhagen Accord and China's commitments to addressing climate change.

In separate replies to letters from Danish Prime Minister Lars Loekke Rasmussen and UN Secretary-General Ban Ki-moon, Wen said the Copenhagen Accord resulting from the UN climate change conference in the Danish capital last year laid the foundation for advancing international cooperation on climate change and pointed the direction for future negotiations.

The document reflected the political will of all parties to actively tackle climate change, upheld the dual-track negotiating mechanism of the UN Framework Convention on Climate Change and its Kyoto Protocol, and reaffirmed the principle of "common but differentiated responsibilities" for developed and developing countries, Wen wrote in the letters dated Friday. He said China would do its best to honor its commitments on climate change, including a reduction of carbon dioxide emission intensity per unit of GDP by 40 to 45 percent by 2020 against 2005 levels, an increase to 15 percent of non-fossil fuels in the country's total primary energy mix by 2020, and an increase of 40 million hectares of forest and 1.3 billion cubic meters of forest volume by 2020 from 2005 levels.

Wen said China will continue to play an active and constructive role and work jointly with the international community for a meaningful conclusion of the Bali Roadmap negotiations at the Mexico climate talks with a comprehensive, effective and binding outcome that will reinforce the implementation of the convention and the protocol.
