The article examines the prospects for the digital transformation of Ukraine's foreign economic policy in the context of international digital trade/economy agreements, especially the Digital Trade Agreement between the United Kingdom of Great Britain and Northern Ireland and Ukraine. The economic and legal effectiveness of these agreements in the process of digital transformation of foreign economic policy (foreign trade) in Ukraine and at the international level is proven. To increase their effectiveness and accelerate implementation, the political and legal framework is of great importance. Under other circumstances, the realisation of such agreements will be complicated by the need to bring domestic legislation in line with their provisions, as the case of Ukraine shows. It is substantiated that the implementation of the Digital Trade Agreement between the United Kingdom of Great Britain and Northern Ireland and Ukraine is complicated by the lack of national legislation regarding electronic document management in cross-border trade; the slow pace of implementation of international legislation, for example, on personal data protection; the existence of differences in the legislative approaches of the European Union and the United Kingdom of Great Britain and Northern Ireland regarding certain issues of trade in goods and services etc. It is emphasized that certain norms of the agreement are declarative and that it does not address some important issues that can be of great value for cross-border trade in the future. The expediency of Ukraine's constant participation in international cooperation in order to modernize foreign economic and national economic policy, taking into account the requirements of international documents and current challenges, is reasoned. In this context, constant monitoring, study of foreign experience and analysis of the consequences of resolving such important issues as cross-border transfer of information by electronic means, localization of data and entities that provide their transfer, non-discrimination, etc. are vital.
