August 15, 2025, marks the 20th anniversary of Chinese President Xi Jinping's ecological concept that "lucid waters and lush mountains are invaluable assets," which has become a guiding principle for China's green development and ecological conservation. This philosophy emphasizes the integration of ecological protection with economic growth, creating a sustainable and virtuous cycle. Under Xi's leadership, China has transformed polluted and barren regions such as Zhejiang's mountain villages and the Saihanba area into thriving ecological and eco-tourism destinations, showcasing successful examples of environmental restoration and green prosperity. Efforts include combating desertification in the Horqin and Hunshandak sandy lands, restoring biodiversity, and pioneering green technologies like "green steel" and solar energy in deserts. These initiatives have led to cleaner air, clearer water, and greener land, contributing to China's dual carbon goals aimed at transforming the economy into a green, low-carbon, and circular system by mid-century. International experts and organizations, including WWF and scholars from the United States and Belgium, recognize China's approach as a model for balancing economic growth with environmental sustainability. National Ecology Day highlights these achievements and ongoing projects such as coral restoration, wetland conservation in the Yellow River Delta, and the conversion of abandoned coal mines into clean energy hubs, reflecting China's commitment to a greener future and global ecological governance.
