The Belt and Road Initiative is an important concept of harmonious development between our country and other countries. With the deepening of the Belt and Road Initiatives understanding, the demand for export-oriented talents of international business major in higher vocational colleges is becoming higher and higher. At the same time, more and more talents are needed. Compared with the past, todays professionals in the Belt and Road Initiative need to have innovation ability, communication ability, learning ability and operation ability. These requirements can promote the progress of talents and change the training methods of export-oriented talents of international business major in higher vocational colleges. As a higher vocational school, it is necessary to determine the corresponding teaching content, allocate the teaching staff and teaching management methods in order to cultivate export-oriented talents that meet the requirements for the country. 展开更多
