The success of diplomatic relations is closely linked to the understanding of cultural differences and the proper application of diplomatic protocol. In the countries of the Central and Eastern European region, the diverse historical experiences, collective memories, and socio-cultural characteristics significantly shape both formal and informal diplomatic behavior. This paper examines how cultural differences influence the application of diplomatic protocols in the region, with a particular focus on the role of cultural sensitivity in diplomatic interactions. Adopting a qualitative, multiple case study approach, the research analyzes contemporary diplomatic incidents in which culturally embedded symbols, gestures, dress codes, and gift-giving practices led to protocol unconventionalities or failures. The findings demonstrate that a lack of cultural sensitivity may result in misunderstandings, public embarrassment or diplomatic tension, while culturally informed protocol practices can contribute to strengthening bilateral and multilateral relations. By integrating cultural sensitivity theory with the analysis of diplomatic protocol and providing empirical evidence from Central and Eastern Europe, the paper contributes to the literature by offering a region-specific and practice-oriented perspective on diplomacy. The paper highlights how seemingly minor protocol deviations can carry significant symbolic and political meanings in culturally sensitive contexts, thereby influencing the elusiveness of international relations.
