Zheng nengliang (positive energy) (正能量) is an expression commonly used in Chinese political discourse.[1][2][3][4] First popularized in 2012 by Xi Jinping at the 18th National Congress of the Chinese Communist Party where he used the phrase to call on officials to enhance the country's soft power and promote better relations with the United States, it has since become central to other areas of government policy.[5][6]
