Attracting foreign direct investment (FDI) to contribute to Vietnam's limited development resources is an objective and indispensable activity. In fact, the investment attraction activities have gained many important achievements in stimulating economic development, curbing inflation and creating jobs. Nevertheless, in many prior studies, there were less discussion on the important role of political factors in the relationship with FDI attraction in Vietnam. Therefore, this study aims to explore that relationship through three variables such as the transparency, the similarity in political characters, and business policies. The findings show the significant effects of those studied factors on the FDI attraction within Vietnam context.
