Wind power projects have developed very quickly in China due to government policies. Between 2005 and 2009, the installed capacity of wind power in China experienced annual growth of over 100 percent for five years in succession.

As for solar energy, the Chinese government in 2009 published The Interim Measures for the Administration of the Financial Subsidy Funds to the "Gold Sun" Exemplary Projects to support its development.

In April this year, China also modified its Renewable Energy Law. The modified law "provides a strong legal support to the development of renewable energy," said Su Wei, head of the climate change department of China's National Development and Reform Commission.

In Cancun, a Mexican resort city, about 25,000 participants from governments, businesses, nongovernmental organizations and research institutions in almost 200 countries are attending the climate change talks, scheduled for Nov. 29 to Dec. 10.

The Cancun conference serves as another chance for the international community to advance the "Bali Road Map" negotiations after the UN Climate Change Conference in Copenhagen last year, which failed to reach a legally binding treaty for years beyond 2012.

The negotiators at the Cancun conference will try to establish a replacement for the Kyoto Protocol, which obliges rich nations except the United States to cut greenhouse gas emissions by an average of 5.2 percent below 1990 levels by 2008-2012, although chances of reaching agreement appear slim.

They will also deal with issues such as green technology transfer and additional financial support to developing countries.
