The 1994 Agreement on Agriculture, which emerged from the Uruguay Round, imposed the first real international trade disciplines on agriculture, including rules on market access, export subsidies, and domestic support. However, no further progress was made at the Doha Round. Today, many WTO members continue to seek tighter constraints on trade-distorting domestic support, while others seek more room for producer support related to developing countries’ food stocks. With the next WTO ministerial conference (MC13) scheduled for February 2024, it remains to be seen if progress will be made on these critical issues.

This trade policy seminar will provide a review and future-oriented discussion on domestic support, featuring Lars Brink and David Orden, authors of the recently published book Agricultural Domestic Support under the WTO: Experience and Prospects. The authors will examine the domestic support disciplines in the Agreement on Agriculture, the support governments provide, and the accommodation of support that targets sustainability and climate change goals. Taking recent dispute settlement cases into account, they will evaluate one of the most difficult aspects of the Agreement — the measurement of market price support. Their presentation will be followed by comments from international trade experts and a Q&A session.
