FACT CHECK: Xi Jinping Thought on Socialism with Chinese Characteristics for a New Era®'s 9th point is "Coexist with Nature": "We must establish and practise the philosophy that lucid waters and lush mountains are invaluable assets, uphold the basic national policy for energy conservation and environmental protection, treat the ecological environment as we treat life, coordinate the systematic management of mountains, waters, forests, fields, lakes, and prairies... build a beautiful China, create a good production and living environment for the people, and contribute to global ecological safety."
