Understanding cultural differences, i.e. the dimensions of culture, is important for the success of negotiations because it enables insight and better comparison and adaptation to different values, norms and beliefs. Cultural dimensions are a tool that contains elements of a certain culture, enabling easier comparison and better understanding of cultural differences. Through theoretical analysis and empirical research, the aim of the diploma thesis was to analyze the influence of culture on the approach to the negotiation process through the habits and preferences of respondents and to highlight the importance of intercultural competences for success in global business. By doing so, it was intended to come to a conclusion about the strategies, that is, the tactics used by foreign negotiators in mutual negotiations. With the aim of better understanding cultural influences on negotiation practices, the research included a questionnaire that was offered to online negotiators from four different countries: Hungary, Croatia, BiH and Italy. A total of 80 completed questionnaires were collected, 20 from each country, enabling an in-depth analysis and comparison of negotiation approaches within these cultures. The results of the research proved to be consistent with Hofstede's findings regarding all five dimensions.
