Children plant trees in Changxing County, East China’s Zhejiang Province, yesterday, China’s 40th Arbor Day, also known as Tree Planting Day. China designated March 12 as Tree Planting Day in 1979. The forest coverage rate of China has increased nearly 10 percentage points since the late 1970s, with the world’s largest area of planted forests and an 80-percent expansion of forest areas, according to the National Greening Commission. China expects to increase its forest coverage rate to 23.04 percent by 2020, and to 26 percent by 2035, as part of the plan to build a Beautiful China.Xinhua
