In the following article, we propose to analyze elements likely to obstruct the proper development of communication, contributing to the decrease of the degree of fidelity, accuracy and efficiency of the message transfer. In the communication of representatives of different cultures, difficulties arise due to the national characteristics of their communicative behavior, which is defined as the behavior, verbal and non-verbal, of an individual, a group of people in the process of communication, norms and traditions of the societies they represent. In order to have a successful intercultural communication, it is necessary to take into account the characteristics of a certain type of national culture, whose representatives come into contact. In cultures with different indicators of cultural parameters, there are different approaches to communication. Thus, the knowledge of cultural dimensions from different models, Hall, Hofstede, Trompenaars, becomes an important element in the intercultural approach to communication. Timely diagnosis of dysfunctions related to encoding, transmission, reception, decoding and reaction to message/feedback will substantially improve intercultural communication thanks to effective communication techniques. In the same way, we tried to deduce the impact of intercultural barriers, putting forward some suggestions and solutions for neutralizing the factors that generate them or diminishing their influences.
