After thirty years of rapid development, China has become the second largest economy in the world. In order to strengthen economic cooperation with countries along the Belt and Road and assume more responsibilities as a major power, China has put forward the Belt and Road Initiative, which puts great pressure on the demand for Business English talents in society. However, at present, there is a shortage of high-level Business English talents in China. The traditional Business English talent training model cannot meet the needs of the business industry, which results in the serious disconnection between the cultivation of business talents and the market demand. Under the background of the Belt and Road Initiative, how to cultivate Business English talents has become a strategic issue. This research firstly combs the research of Business English talent training objectives and training model from the perspective of ESP Needs Analysis Theory, and then discusses the drawbacks of the current Business English training model from such aspects as curriculum setting, teaching system, and evaluation system, and gives suggestions in order to explore an appropriate Business English training model that meets the needs of the Belt and Road Initiative.
