On 18 May 2023, the Chatham House Africa Programme and the Konrad-Adenauer-Stiftung (KAS) Tanzania office convened a private roundtable meeting in Arusha. The discussion focused on Tanzania’s foreign policy priorities for regional engagement in both Southern and Eastern Africa, including the status of economic integration and trade initiatives, governance and political ties, and collaboration to address peace and security challenges. The roundtable marked the second event in a project partnership series between KAS and Chatham House on Tanzania’s Foreign Policy Agenda: Economic Diplomacy and International Agency. The series aims to encourage informed dialogue and debate at an important moment for Tanzania’s external engagements: the country’s main foreign relations strategy document, the ‘New Foreign Policy’, was adopted in 2001, but an official review has been commissioned by President Samia Suluhu Hassan and is to take place in 2023. The first event under this collaboration, a webinar on Tanzanian agency in the international system, was held in November 2022. A summary of that first meeting is available to read. This Arusha roundtable meeting was held under the Chatham House Rule. The following document summarizes the key findings and themes of the discussion.
