However, Xi said the country still has a lot to do to make up for the environmental arrears of the past, and its lack of forest cover and vulnerable ecology remain problems requiring substantial efforts to conquer.

He called on officials at different levels to lead the public in making unwavering efforts to continue with tree planting programs.

It is also important to act on the understanding that clear waters and lush mountains are invaluable assets, promote the high-quality development of forestation programs and continue to promote the development of forested cities and rural areas, he said.
