Vietnam is a country with strength in agricultural development and its agricultural production not only meets the food demand of the whole country, but also serves the export, contributing to the state budget. In order to develop the Vietnam's agricultural sector sustainably and be competitive in the international agricultural market, it is necessary to have a large investment in this area. Regulations on investment incentives in the agricultural sector plays an important role in attracting private investment to develop this sector. However, current regulations on investment incentives have revealed many limitations and inadequacies which can lead to obstacles in attracting investment in this field. This paper deeply analyzes the limitations and inconsistencies of Vietnam’s regulations on investment incentives in the agricultural sector, and makes some suggestions to improve its investment incentive regulations.
