The Zhanjiang Mangrove National Nature Reserve is the largest and densest natural reserve of its kind in China. Xi inspected the mangrove area on the Jinniu Island in Huguang Township, Mazhang District, in the eastern part of the reserve, and learned about the growth of mangroves and the surrounding ecological environment. He stressed that the mangroves are a "national treasure" and should be well protected like we do with our eyes. Strengthening marine ecological environment is an important component part of overall ecological conservation. We should continue to pursue green development, make unremitting efforts from generation to generation to build a beautiful China, and make China's contribution to protecting the global village.
