: The Black Sea region has strategic geopolitical importance where the routes of Europe, the Caucasus, Asia, and the Middle East intersect. Ensuring stability and security in the Black Sea area is essential for emerging new security architecture. In search of balance, the challenges are met by the Three Seas Initiative (3SI) and the deepening of strategic relations with the United Arab Emirates. The UAE, anchored in the Euro-Atlantic partnership and with extensive influence, emerges as an interesting strategic partner. When analysing the Three Seas Initiative, it should be noted that the United States of America joined the implementation of 3SI, seeing it as an opportunity to pursue American interests in LNG markets, and in a broader geopolitical dimension, combining this initiative with projects in the Middle East. This research paper is the first to analyse the foreign and security policy of the two Black Sea countries, Bulgaria, and Romania that participate in the Three Seas Initiative, from the geostrategic perspective and relations with the United Arab Emirates. The research work is based on empirical research, and the results of which are largely derived from 10 years of direct observation, as well as the participation of the author of the article in many initiatives related to cooperation between all 3SI countries with the United Arab Emirates, among others as an Ambassador, Senior Advisor at Dubai Expo 2020.
