The relevance of the research topic consists in the high dynamics and unpredictability of the factors that influence the development of tourism within cross-border cooperation. Because of the sanctions implementation against the Russian Federation, the number of cross-border cooperation projects has decreased, which has led to a decrease in the integrated tourist product competitiveness of neighboring territories. Thanks to the package implementation of state support measures for domestic tourism, this sector of the economy is developing steadily towards the Kaliningrad region due to the attraction of Russian tourists. However, the international potential of the region is practically not involved. Therefore, the study of the prospects for crossborder cooperation of the region with the countries of Europe is extremely important. To study these issues, the authors of the article used methods of economic-statistical and factor analysis, economic and mathematical modeling. As a result of the research, scientific and theoretical approaches to the definition of the essence of the notion of "competitiveness" were summarized and its features were substantiated in relation to the regional tourist product. The modern indicators of the competitiveness of the regional tourist product of the Kaliningrad region are determined; problems with ensuring its competitiveness are justified. A model is designed to ensure the competitiveness of the tourism product in the strategy of cross-border cooperation, which can be applied not only in relation to such projects in the Kaliningrad region, but also in other areas of the Russian Federation or other countries.
