June 5 is World Environment Day. This year's theme focuses on land restoration, desertification and drought resilience. Strengthening the comprehensive prevention and control of desertification and deepening the construction of key ecological projects such as the "three north" project are of vital importance to China's ecological security, the construction of a powerful country and the sustainable development of the Chinese nation. On June 6, 2023, General Secretary Xi Jinping chaired a symposium on strengthening the comprehensive prevention and control of desertification and promoting the construction of key ecological projects such as the "three north", and delivered an important speech, emphasizing "striving to create a new miracle of China's desertification prevention and control in the new era", and proposing "striving to fight a" three north "project in about 10 years". Over the past year, the "Three North" project has accelerated its progress around the key and difficult points of desertification control, and more intense green has been spreading in the northern part of the country.
