International Regulatory Cooperation in Agency Practice: Assessment and Best Practices

This report assesses how U.S. federal agencies engage in international regulatory cooperation (IRC), especially in the decade following Executive Order 13,609. It explores agency practices, obstacles to cooperation, and the broader global context that shapes regulatory convergence. Despite modest institutional changes, the report finds that most IRC activity remains decentralized and inconsistent, driven by individual agency needs rather than coordinated policy. It offers practical recommendations for improving transparency, interagency collaboration, and long-term strategy in cross-border regulatory efforts.
