Communication is one of the most basic elements of business, whether it is a research team that collects evidence of market trends or it is an inspiring leader who leads the company towards meeting common goals. Since today's business has crossed international borders in order to market its products and services and enter into partnerships with other companies, it is necessary to include all forms of modern business communication. Communication has changed over the past, ranging from communication through symbols and graphic drawings to modern communication through the Internet and social networks. Terms via Facebook and Twitter nullify verbal communication. The modern way of communication is increasingly helping companies and firms to promote themselves in the business world. In order to achieve successful international relations, it is necessary to be flexible around studying different cultures. There are concepts such as ethnocentrism and xenophobia that undo just that flexibility. However, as globalization has a huge impact, it just gives an opportunity for people to get to know each other better, to seize the opportunity to learn something new and useful from people of different cultures. Of course, in order to avoid conflicts during the communication process, it is necessary to study non-verbal communication so as not to insult the interlocutor of different cultures.
