The global ecological crisis has impacted the Belt and Road Initiative (BRI) region, and due to the diverse geographical characteristics, the ecological problems in countries along the Belt and Road vary. Overcoming these environmental and ecological challenges is essential for advancing and genuinely implementing green development, and has become a practical necessity for building a “Green Belt and Road.” China, the creator of the Green “Belt and Road Initiative”, actively aligns with international environmental protection standards and plays a leading role in global ecological conservation efforts. China vigorously promotes the development of key policy documents for the Green Belt and Road, providing institutional support for the initiative’s environmentally friendly construction and development. Under comprehensive theoretical planning, various green practices have been implemented, including thematic in-depth research on the Green “Belt and Road” and the “2030 Agenda for Sustainable Development,” the establishment of the “International Green Development Coalition” along the Belt and Road, the implementation of overseas investment and green finance, and the proposal of the “Ten, Hundred, Thousand” initiative for South-South Cooperation on Climate Change. These green practices clearly indicate China’s commitment to building ecological civilization and its relentless efforts toward advancing the construction of a global ecological community with shared-benefits.
