It's the common responsibility of all countries to develop renewable energy and countries shall work together to attain genuine development of renewable energy so as to combat climate change, Liu Qi, vice chairman of the National Energy Administration (NEA) said Wednesday.

Addressing the Delhi International Renewable Energy Conference 2010, which opens here on Wednesday, Liu suggested that participants of the conference work out a road map for the development of global renewable energy and help individual countries put forward their own road map in this regard in accordance with their own resources, technology and economic conditions.

China would like to open its renewable energy market to the maximum since professional division of labor is the best way to improve efficiency and reduce costs, he said.

Commenting on the possible consequence of a U.S. probe into the Chinese clean energy policies on the sidelines of the conference, Liu said that China's renewable energy sector would not be much affected by it.

Liu said China's supportive policies focus on basic research, development and demonstration projects.

The U.S. Trade Representative's office started on Oct. 15 the probe dubbed Section 301 of Trade Act 1974, in response to a United Steel workers Union's complaint on Sept. 9 that China' s support for its renewable energy sectors gave Chinese producers unfair advantages over competitors.

China will not readjust its renewable energy policies due to unjustified U.S. claims of unfair subsidies, Liang Zhipeng, head of the renewable energy department of the NEA told Xinhua.

Liang added that advanced low-cost technologies on renewable energy should be promoted in the world, urging the international community to help developing countries increase their capacity to utilize renewable energy and noting that no trade barriers should be introduced in the sector.

China imported 2.7 billion U.S. dollars of equipment and multi-crystal silicon in solar photovoltaic sector since 2009 from the United States, while only exporting 700 million dollars of solar photovoltaic products to the United States, according to Liang.

Additionally, China now provides around 3 billion RMB (448 million dollars )in subsidies to the sector of renewable energy compared with 10 billion dollars of subsidies in the United States.

The three-day event draws more than 9,000 delegates from over 40 countries to discuss green economy, climate change, financial innovation, technology and transport, policy support and other issues relating to renewable energy.

This is the fourth conference of its kind. The previous conferences were held in Bonn in 2004, Beijing in 2005 and Washington in 2008.
