Aerial photo taken on April 30, 2018 shows the scene of the dismantling site of a chemical factory along the Yangtze River in Yichang City, central China's Hubei Province. Since 2017, Yichang has carried out a series of projects to cut pollution and upgrade the chemical industry to protect the ecological environment along the Yangtze River. China has pledged to coordinate its efforts of environmental protection and economic development in 2019, an important year for winning the tough battle against pollution. At the annual Central Economic Work Conference earlier this month, authorities called for building on this year's achievement in pollution control, making more efforts and input in 2019. Since the turn of this year, China has made solid efforts to combat pollution and seen constant improvement of the environment. The Central Economic Work Conference made it clear that local governments must avoid past simple and unscrupulous practices in dealing with environmental problems. (Xinhua/Xiao Yijiu)
