“The Belt and Road Initiatives” is the essence of the ancient Silk Road extension and development，reflecting the new concept of international cooperation in China. Under the theme of “peaceful development and win-win cooperation”，it is another major international initiative. At the same time，unimpeded trade plays a fundamental and key role in the belt and road Initiative cooperation practice. This paper analyzes the status quo of import and export trade，including the countries along “The Belt and Road Initiatives”，China and countries around the world，as well as China and the countries along “The Belt and Road Initiatives”. Moreover，this paper chooses the relevant data from 2000 to 2015 between China and the 43 countries along “The Belt and Road” as an analysis of the sample. Through the expansion of the trade gravity model，this paper empirically studies the impact of variables on the unimpeded trade of China and the countries along “The Belt and Road”. These variables include GDP，per capita GDP，population，trade distance and bilateral trade exchange rate，national characteristics and trade organization，etc. In addition，this paper considers Indonesia as a study case，which has the largest overseas Chinese business community. The roles of Chinese business enterprises are explored in the unimpeded trade from the perspectives of politics，economy and culture.
