This work updates the APEC Authorized Economic Operator (AEO) Compendium, assembled in 2010, with results of a new survey. APEC customs authorities were provided a survey questionnaire about their AEO program. Based on this new survey, a matrix was created to determine where APEC AEO programs converge with or diverge from each other. Respondents were subsequently given an opportunity to review and comment on preliminary drafts of this report, and to provide clarifying data and/or additional information. This final report incorporates and addresses all relevant comments from member economies, and suggests ways to improve APEC AEO convergence and regional economic integration.
