Communication is the process of transferring information most often through the language. In modern society people communicate in different ways, and the way they communicate is the way they live, so people in different societies around the world communicate in different ways. Human communication is divided into verbal communication and non-verbal communication. Verbal communication is the communication that an individual realizes in speech (and in writing, as a record of speech), and non-verbal communication that is realized by non-verbal signs. The link between communication and culture is extremely important because communication itself affects the durability of culture. Once cultural habits, principles, values, attitudes and the like are shaped, they are communicated to other members of the culture. Exchange information across cultures and social groups defines intercultural communication that seeks to understand how people from different countries and cultures work, communicate and perceive the world around them. Communication in the business environment is of utmost importance because business communication as a very important part of business, organization, management and management greatly affects the company's image and can greatly affect the organization's performance. It is carried out within the organization for the purpose of realizing the plan. When it comes to international business cooperation, understanding the role of culture in international business communication is the key ethnography of communication and interaction sociolinguistics. The vast variety of world cultures make some inability for any negotiator, no matter how skilled and experienced.
