A Diagnostic Trade Integration Study (DTIS) is an in-depth analytical study conducted periodically to evaluate internal and external constraints on a country’s integration into the world economy. The study typically provides for a detailed analysis of the country’s key economic sectors and related trade- and export challenges, and includes a DTIS Action Matrix which identifies critical areas for intervention and suggests policy actions that can help the country overcome those barriers. Studies are conducted by highly-experienced technical teams, who analyze specific sectors of the economy as well as cross-cutting institutional issues such as market access, transportation, trade facilitation, standards, poverty, and gender, among others. On the other hand, the Action Matrix facilitates discussions with government, donors, and the private sectors after the diagnostic study is completed, and serves as basis for policy prioritization and resource mobilization. In Tanzania, a first DTIS was conducted in 2005 (see ‘’2005 DTIS’’ and related documents under the ‘’Documents and Publications’’ section of this website), and an update of that study is currently in the process of being conducted – in both cases, the World Bank was requested by the Tanzania Government to act as lead technical agency. The 2016 Tanzania DTIS Update is funded through the generous support of the Enhanced Integrated Framework (EIF).
