The article examines the role of the World Customs Organization in the implementation of the Agreement on Trade Facilitation (Agreement, TFA), which is one of the important areas of modern multilateral regulation of the international trading system. The article-by-article analysis of the Agreement and the Kyoto Convention, as well as an assessment of the potential and real impact of the WCO instruments on its implementation, was carried out. There is a lack of methods and a system of indicators for evaluating the effectiveness and efficiency of such work, which does not allow assessing the quality and effectiveness of the activities carried out. A key issue in achieving qualitative changes in the implementation of the Agreement would be a detailed diagnosis of the state of affairs in developing and least developed countries, the specification and digitization of data on priority areas, volumes and deadlines for providing them with all types of assistance and support. In conclusion, the importance of adequate self-assessment by countries of their readiness for the implementation of the Agreement, the relevance of the development of the potential necessary for the implementation of the Agreement, as well as bilateral and multilateral cooperation with donors is substantiated. Proposals have been formulated to improve the work of WCO and WTO to ensure timely implementation of the Agreement.
