BEIJING - China will actively develop clean energy and improve energy efficiency to push green development and lifestyles, President Xi Jinping said Wednesday.

He made the remarks in a congratulatory letter to the Eighth Clean Energy Ministerial and the Second Mission Innovation Ministerial, which opened in Beijing Wednesday.

Clean energy development is crucial to the improvement of energy structure, energy security and the promotion of "ecological civilization," Xi said in the letter.

China highly values clean energy development and has taken a series of measures and achieved positive outcomes in this area, the president said.

The country will stick to the basic state policy of energy conservation and environmental protection, Xi vowed.

He urged participants of the two meetings to share knowledge and experience to help bring the world onto a path of green, low-carbon, circular and sustainable development.

The Chinese government has intensified efforts to fight pollution and use more clean energy.

The country has pledged to cut its carbon emissions per unit of GDP by 60-65 percent from 2005 levels by 2030 and raise the share of non-fossil energy use in total consumption to about 20 percent.
