DAVOS - Chinese Premier Li Keqiang pledged on Wednesday to reduce the proportion of fossil fuel in China's total energy mix and promote clean technology.

This marks the latest effort of the world's most populous country in its uphill battle against air pollution and climate change.

When meeting with representatives of the International Business Council of the ongoing World Economic Forum (WEF) in the Swiss mountain resort of Davos, Li said China has pledged to increase the share of non-fossil fuels in primary energy consumption to around 20 percent by 2030, which means that painstaking efforts must be made by the developing country with a population of 1.3 billion.

China will endeavor to lower the proportion of fossil fuel, especially the coal, in the country's total energy consumption, Li pledged.

He also said China will promote clean coal technology, calling on the developed countries to export more such technology and products to China.

The Chinese premier reiterated the principle of common but differentiated responsibility in the battle against climate change.

"We will spare no efforts to pursue low-carbon development," he added.

This year's WEF winter meeting is held in Davos from Wednesday to Saturday under the theme "The New Global Context."
