The paper attempts to compare the cultures of the czech and slovak republic in a business environment. establishing a list of cultural dimensions extracted from reputable models, the authors applied a systematic behavioural comparison of each country. the work of the authors was limited by two factors. firstly, the cultural proximity of the countries provided many slight differentiations. secondly, the analysis was hampered by the few of available cross-cultural statistics for the countries reviewed. the analysis showed that both countries have a narrow cultural gap and share many cultural traits. however, a few noticeable differences were isolated: Particularism, specificism and emotions display. Due to the lack of available reliable quantitative data about the czech and the slovak cultures, further research such as factor-analysis questionnaire is suggested.
