The article’s scientific goal is to investigate the Weimar Triangle countries’ relations with the United Arab Emirates. Therefore, the author asks the research question. Are the Weimar Triangle states’ role and significance increasing in the external dimension of the European Union? Based on the example of the United Arab Emirates, the research adopted a hypothesis. It is the statement that after Brexit, the Weimar Triangle countries have a chance to improve their importance in the EU external activities. Apart from case studies, to revise the hypothesis, the author performed a meticulous comparative analysis. Moreover, the research implemented International Practice Theory as an appropriate tool to investigate the presented issue. This empirical research and its findings resulted from over ten years of the author’s direct observation, analysis, and participation in many initiatives, both in the European Union and in the United Arab Emirates. The Middle East for the Weimar Triangle countries is more significant than just from a trade potential perspective. The situation in this region is also affecting Europe, as well as global security architecture. For this reason, one should develop a coherent and comprehensive EU foreign and security policy towards the region, and the Weimar Triangle formula should be one of its pillars.
