In the business world, globalization and international networking are of great importance. Globalization connects different countries, economies, and cultures. It contributes to better networking and facilitates the exchange of information. Consequently, globalization makes business etiquette much more important, as it is influenced by national culture. To achieve success in the global market, it is essential to understand and be familiar with the various cultures and customs of other countries. Each country is unique, reflecting its traditions and patterns of behavior, making the understanding of business etiquette crucial for success on an international level. Global business requires considerable effort and work, as well as numerous challenges, but knowledge of business etiquette makes overcoming these challenges easier. The purpose of this thesis is to explain cultural differences and demonstrate how business etiquette varies from one country to another. This thesis is structured in five main chapters. The first chapter outlines the subject and objectives of the thesis, as well as the methodology and research. The second chapter addresses the concept of culture and the connection between culture and the business environment. The third chapter focuses on business etiquette, which is divided into subchapters such as introductions, business communication, business meetings, and more. The fourth chapter describes business etiquette in selected countries, specifically Japan, India, Italy, Germany, and the United States. This chapter aims to provide a closer look at each country's etiquette, highlighting certain similarities and differences in behavior. The fifth chapter is the conclusion, summarizing the most important findings from the research.
