The following work aims to highlight cultural differences between Germany and China and their relevance for international relations. It will also give recommendations for business negotiations between German and Chinese parties. After this introduction a definition of culture follows and the reader is introduced to two different models that help develop an understanding of cultural differences. The first one is the model of cultural dimensions by Geert Hofstede, the second one is the model of cultural dimensions by Fons Trompenaars. The end is marked by the section labelled as "conclusion".
