In fact, the American economist Milton Friedman said, “The economic profession almost agreed on the desire for free trade.” Since WTO members are required to submit their free trade agreements to the Secretariat, this database is based on the most official source of information on free trade agreements (in the WTO language known as regional trade agreements). The database allows users to obtain information on trade agreements that have been notified to the WTO by country or by theme (goods, services or goods and services). This database provides users with an up-to-date list of all agreements in force, but those that have not been notified to the WTO may be lacking. Reports, tables and graphs containing statistics on these agreements and, in particular, the analysis of preferential tariffs are presented. .
