Beijing — Premier Wen Jiabao has urged the leadership of all countries to deepen their political will in dealing with climate change woes (灾难) as uncertainties mount (增长) in the months before the United Nation’s conference in Cancun, Mexico, at the end of this year.
Wen made the remarks on Friday when he met with nearly 20 politicians, climate change and environmental ministers worldwide, who are in Beijing this weekend to attend an international forum on green economy and climate change.
Based on the achievements made at the Copenhagen Summit last December, Wen urged the rich countries to further make clear their compulsory carbon reduction targets. “At the same time, we developing countries should make clear our voluntary goal of slowing down climate change,” Wen said.
Wen also urged the developed countries to transfer（转让）climate change friendly technologies to the developing countries, especially the poorest countries and island nations.
During the meeting, Wen said China will redouble its efforts in reducing carbon emissions and improving energy efficiency during the coming years after it finishes its 2006-2010 goal of cutting energy consumption per unit of economic output by 20 percent.
While praising China for its green efforts, former Australian Prime Minister Robert J. Lee Hawke asked China to share its experiences and lessons on energy savings and pollution reduction to the rest of the world to deal with global environmental woes and climate change.
Wen responded: “China, together with the rest of the world, is willing to make its due contribution in coping with global warming and climate change.”
At a banquet for the foreign guests on Friday night, former vice-premier Zeng Peiyan said “Increasing uncertainties are ahead for the climate change negotiations. The world needs more dialogue and cooperation”.
“Climate change woes are our shared challenges but the root lies in the historical emissions by the developed countries,” said Zeng, as president of the China Center for International Economic Exchanges, which organized the weekend climate change summit.
Zeng expected the forum to work as a platform for different countries to communicate their positions freely before the Bonn climate change negotiation in June and the Cancun conference at the end of this year.
