The purpose of this paper is to evaluate the implementation of the UR Agreement on Agriculture in terms of commitment of major area and agricultural trade performance and to explain some issues of the current WTO’s Doha negotiation on agriculture with a prospect of the DDA negotiations.One of the great achievements of the Uruguay Round of trade negotiations was to bring agricultural sector of individual countries to the mainstream of GATT disciplines. Although the evaluation on the performance of the new trading rules under WTO seems differ between exporting and importing countries of agricultural products, the experience of implementing the URAA has revealed several weakness and shortcomings in agricultural reforms. Therefore agricultural sector will remain as an important negotiation area in the WTO DDA round. The ongoing DDA negotiations on agriculture will likely result in further reductions of trade-distorting domestic subsidies and termination of export subsidies as well as substantial reduction of tariffs and expansion of the market access.
