The development of a city is closely related to the strategic trend of a country. The “Belt and Road” Initiative was proposed by President Xi Jinping in 2013，and the Second “Belt and Road” Forum for International Cooperation was successfully held in 2019，demonstrating the spread of this Initiative to various regions and countries around the globe. From conception to implementation and then to fruition，the “Belt and Road” Initiative has received wide response from the international community and yielded fruitful results through cooperation. The Initiative has continued to deepen beyond its own geographic scope，bringing together countries that recognize international multilateral cooperation mechanisms and are disposed to seek common development and cooperation. From the perspective of international cooperation，the natural multilateralism of the Initiative provides Chinese solution to global development and governance issues. From the perspective of urban development，the implementation of the Initiative has brought new opportunities for the development of Chinese cities in the new era. Xi’an has strategic geographic location，high-end leading industries，unique historic culture，and various favorable policies. By virtue of these urban attributes，Xi’an will move faster into the historical fast lane of urban rejuvenation through the “Belt and Road” Initiative.
