Cross-cultural communication, which is also frequently referred as intercultural communication, is a field of study that looks at how people from differing cultural backgrounds endeavour to communicate. 

Intercultural communication is important to international businesses as it examines how people from various cultures, beliefs and religions come together to work and communicate with each other. Demands for intercultural communication skills are increasing as more and more businesses go global or international.

The application of cross-cultural communication studies began after World War II. It started originally within businesses and the government both seeking to expand globally. Now, there are many theories that set principles to help explain the basis of intercultural communication, including general business, management and marketing. There are also several successful educational projects that concentrate on the practical applications of these theories in cross-cultural situations. 

In short, the main objective of cross-cultural communication studying is to earn respect from others and help to reduce the possible misunderstanding from different cultures groups.
