Agriculture is one of the most important sectors in both developing country members and developed country members. However, the subsidy supports the agricultural economy and domestic agricultural production as well as agricultural exports with the unfair way. In 2015, Nairobi Minister Declaration is officially passed which impacts on the agricultural sector. It marks a new step forward in making the fair in all WTO members about the agricultural trade and the profits in the agricultural export subsidies, especially Vietnam. Thus, I decided to research this topic for my dissertation.
