The conditions of establishing, motives, and goals of the participants in the creation of the ‘Weimar Triangle’ are studied in the paper. It is determined that the collapse of the bipolar system of international relations led to a change in the political structure of Europe and the world, which caused the transformation of previous interstate associations. Emphasis is placed on the development of French-German and German-Polish cooperation through the prism of political changes in Central Europe in the late 1980s and early 1990s. The ‘Weimar Triangle’ is one of the forms of interregional cooperation. At the heart of this partnership is the centuries-old experience of international relations of three states: Germany, France, and Poland. In the history of their cooperation and confrontation, one can find the answer to the question: why just these states created an advisory board to address the main issues of modern international relations (political, economic, social) in Europe in August 1991. The study of this phenomenon is especially relevant at the period of the European Union values crisis. The paper reveals that Ukraine’s interest in the ‘Weimar Triangle’ formula is, in particular, in the belief that its strategic choices determine geopolitical relations between the US, the European Union, the Russian Federation, and Ukraine. Thus, the formula of the ‘Weimar Triangle’ becomes essential. After all, it unites the states which, taking into account their position, membership in NATO and the European Union, and in the case of France and Germany – in connection with their political and economic potential and the relevant relations with Russia, are a logical link between the components of geopolitical and geostrategic space of Ukraine.
