Building the Green Silk Road is an important goal of the Belt and Road and an important embodiment of the new development concept pursued by China in the new era. Over the past decade，China has always adhered to the concept of green development and constantly improved the top-level design of the Green Silk Road as one of the important contents of promoting high-quality development of the Belt and Road. At present，the Green Silk Road has achieved solid progress and become a highlight of the Belt and Road cooperation. The influence of the Belt and Road Green Development Alliance and the Belt and Road Green Investment Principles continues to expand. Important progress has been made in the Belt and Road in green investment，green finance，green infrastructure and climate change. However，the construction of the Green Silk Road still faces great challenges，due to the complex diversity and fragility of the national ecological environment，the lack of willingness to achieve green and low-carbon development，the unbalanced ability of overseas investment enterprises and the competition for the right to speak of green development. Looking ahead，the Green Silk Road will continue to be an important part of high-quality Belt and Road cooperation，an important opportunity for China to actively participate in and lead global environmental and climate governance，and an important practical platform to promote the building of a community of shared future for mankind.
