China has earmarked more than 7.1 billion yuan (about 930 million US dollars) for technology innovations to cope with climate change since 2001, said Science and Technology Minister Wan Gang on Thursday.

Investment rose sharply in 2006 when China adopted its 11th five-year program, said Wan at a press conference.

"China is determined to find answers to climate change through science and technology," said Wan.

China has made big efforts to cope with climate change, said Wan, adding that ministries and local governments had approved a series of environmental protection policies.

He also said some Chinese enterprises were using technology to reduce energy consumption and pollution discharge.

The Ministry of Science and Technology launched on Thursday China's Scientific and Technological Actions on Climate Change. It aims to enhance the role science and technology play in responding to climate change.
