On January 29, 2010, Premier Wen Jiabao said China positively evaluates and supports the Copenhagen Accord resulting from the UN climate change conference in separate replies to letters from Danish Prime Minister Lars Loekke Rasmussen and UN Secretary-General Ban Ki-moon.

Wen pointed out that the Copenhagen Accord reflected the political will of all parties to actively tackle climate change, reaffirmed the principle of "common but differentiated responsibilities" and upheld the dual-track negotiating mechanism of the UN Framework Convention on Climate Change and its Kyoto Protocol. The Accord set the two draft texts presented by the chairs of the two Ad hoc Working Groups as the foundation for the next-phase negotiations and locked up the consensus reached by all parties. Wen said the Copenhagen Accord laid the foundation for achieving outcome at the Bali Roadmap negotiations and advancing international cooperation on climate change, pointing the direction for future negotiations.

Wen reaffirmed China would take positive measures and 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 so as to contribute to the tackling of climate change.
