Special attention is paid to the study of national and cultural characteristics of representatives of Arab society, and factors that make influence on the establishment and development partner relations with Arabs. The basic moral values, cultural, national, linguistics norms are briefly formulated in the article. Knowledge of that contributes to the successful conduct of intercultural communication at the “East-West” level. In the Arab countries, the traditions and customs of business ethics and communication, in general, are predominantly developing and changing because of the openness of most countries of the world and the interaction in various spheres (economic, educational, cultural, military, political, etc.).
