UN Secretary-General Ban Ki-moon said in Bali, Indonesia, Thursday that China's position on climate change is constructive and China has sent a positive signal to the world.

The secretary-general said he held a "very constructive" telephone conversation with Chinese Premier Wen Jiabao on climate change before coming to Bali for the United Nations Climate Change Conference.

China is committed to strengthening ability and capacity to fight climate change and to making new contribution to protecting the global climate, said a Chinese official on Friday.

China has set very ambitious domestic goals to combat climate change and is taking a series of practical and proactive actions including setting up regulatory, legal, financial, and economic instruments.China is committed to controlling green house gas (GHG) emissions by 2010 and endeavors are to be made to achieve such goals as reducing energy consumption per unit GDP by 20 percent; increasing the share of renewable energy to 10 percent; stabilizing nitrous oxide emissions from industrial processes at 2005 level; controlling the growth of methane emissions; increasing the forest coverage rate to 20 percent and increasing carbon sink by 50 million tons over 2005 level.

China is closing down those backward energy intensive plants and replacing them with advanced ones. China is also implementing the 10 priority energy conservation programs targeting at more than 1,000 key energy intensive enterprise.

For adaptation to climate change, China is trying hard to enhance capacity for disaster prevention, warning and mitigation. Efforts are also being made to improve the adaptation capacity in the agriculture, water resources, ecosystems, health, tourism, andother sectors. The formulation of national adaptation strategy is well underway.
