Abstract: The Belt and Road Initiative aims to achieve win-win cooperation between China and countries along the route. In order to strengthen the results of the interconnection between China and the five central Asian countries in the “Silk Road Economic Belt”, the role of trade should be brought into full play. In view of the strong complementarity of trade between China and Central Asia, it is possible to carry out the establishment in a planned and step-by-step manner. The China-Central Asia Free Trade Area will improve the operational efficiency of the Eurasian Continental Bridge, break through the bottleneck of land transportation, and strengthen coordination with other domestic economic belts.
