Ethnic tourism is employed by a great number of countries to facilitate economic development, especially in remote and backward areas. Though a substantial literature is devoted to the impacts of ethnic tourism, little research has been done on examining the cultural issues associated with ethnic tourism. The paper focuses on folkloric tokens, presages and beliefs related to ethnic strangers or persons of another faith spread along the East Slavs. They are considered as factors which can negatively affect the destination attractiveness of the region. The urgency and novelty of the research is determined by the lack of knowledge of this topic both in Slavic and foreign studies. Based on the involvement of a wide range of sources and field research materials, the authors come to the conclusion that the analyzed omens and tokens are a linguistic declaration of taboos, permissions, warnings, advice, etc. in situations used by the traditionbearers to establish proper relationship with foreigners.
