Since 2019, the Elliott School of International Affairs, most notably under its European Union "Jean-Monnet" Center of Excellence, has launched a program of workshops, executive courses, and data collection that explore subnational governance and diplomacy, primarily but not exclusively in the transatlantic sphere. On 5/20, our next hybrid workshop will aim to highlight U.S., European, and Canadian subnational perspectives on international trade policy (while recognizing that trade negotiations are still in flux and could yet yield positive results).
