The study investigates how sportsmanship functions as a negotiation tool between Saudi Arabian and Hungarian SME business professionals during their dispute resolution process. It investigates sportsmanship-related behaviors through the examination of five specific elements which include fairness, respect, emotional control, cooperation, and professionalism. It also used a questionnaire-based approach to gather data from 24 participants who included 12 Saudi Arabian respondents and 12 Hungarian respondents. The results show that both groups reported high levels of sportsmanship, although Saudi respondents showed slightly higher scores in emotional control and respect-related behaviors. The findings also show that both groups exhibited identical patterns of cooperation and win-win orientation. The thesis demonstrates that sportsmanship functions as an international business negotiation tool which helps parties achieve better communication standards while decreasing their chances of miscommunication and enhancing their ability to work together across different cultures.
