China will intensify efforts to "keep our skies blue, our waters clear and our lands pollution-free," Chinese Premier Li Keqiang said as he delivered the annual government work report at the fourth session of the 13th National People's Congress on Friday.

Li said China will strengthen comprehensive measures and joint efforts on air pollution prevention and control, with the goal that clean heating accounts for 70 percent of all heating service in northern China. 

A ban on solid waste imports, introduced in 2018, will remain in place, he said, adding that as a member of the global village, China will continue to play its role in the international response to climate change, including developing new energy sources and reducing carbon emissions.
