Why do these differences exist? What method can help us overcome these cultural differences? According to a lot of literature, we can summarize three main differences. The reasons for these differences mainly lies in the cultural differences between the two countries. "On account of the totally different history and culture of the two countries, the Sino-US negotiators’ way of thinking, values and other legal concepts are totally different." (He 29). "Because the cultural background is not the same. the speech and deportment, the ways of doing things and habits are different." (Wan 87). "From two different cultural background, negotiators have different values and ways of thinking, so it also determines the different negotiating styles. "(Pang 44).
