2023 is the tenth anniversary of “the Belt and Road” initiative. Over the past 10 years，China and neighboring countries have achieved fruitful results in the construction of “the Belt and Road” initiative. In recent years，the scale and quality of trade and economic cooperation between China and neighboring countries have improved，and areas such as sustainable development and scientific and technological cooperation have become new directions for the development of “the Belt and Road” initiative. However，due to rising instability in the world economy and intensified geopolitical conflicts，the joint construction of “the Belt and Road” confronted with new challenges. Among them，problems such as the lack of protection mechanism of overseas interests，debt sustainability and transparency issues，and the relative slowness of people-to-people and cultural exchanges are more obvious. To promote high-quality joint construction of “the Belt and Road” between China and neighboring countries，it suggests to speed up the formulation of overseas investment promotion laws，strengthen debt transparency and sustainable development in line with international standards，and build a practical and effective dispute settlement mechanism and explore the use of the concept of law as a symbolic feature of high-quality joint construction of “the Belt and Road”，in order to explore and strengthen the voice in international discourse.
