IntroductionWith the rapid development of science and technology, the world is becoming a global village. The communication among international business negotiators is also becoming more and more frequent. The communication in international business negotiation can be divided into two kinds, verbal communication and nonverbal communication. On one hand, nonverbal communication is universal as it is used accompany with verbal messages or independently. On the other hand, nonverbal communication is important in international business negotiation, because it can exert influences on peoples communication, reflect the peoples thoughts and supplement the verbal communication. What is more, one distinct feature of nonverbal communication is its diversity in different countries. Thus, if people ignore it or cant handle it appropriately, it will inevitably cause conflicts or misunderstanding when two or more cultures encounter each other.This paper mainly explores the significance, classification and diversity of nonverbal communication in international business negotiation. Finally, it put forward some suggestions on how to avoid the conflicts or misunderstanding in international business negotiation.2. Literature ReviewThe employment of nonverbal communication has a long history, which was the main way of transferring messages by our ancestors in human society before the invention of languages.

Jandts Intercultural Communication in 2000 all have profound research on this special communication skill. In China, there are also plenty of works in this field, such as Liu Runqings Language and Society in 1989, Hu Wenzhongs Culture and Communication and Cross-cultural Nonverbal Communication in 1995 and 1999. However, most of these researches are not specific enough. Although the researches on nonverbal communication developed so fast and achieved delightful results, the common people, especially the international business negotiators still attach inadequate importance to the influence and employment of nonverbal communication on the entire process of communication. This paper focus on the importance of nonverbal communication in international business negotiation.3.
