Culture of western and oriental countries

Why do representatives of different cultures understand and perceive the world so differently?
The most obvious differences are observed in European and Asian ethnic formations.Oriental culture is mostly characterized by contemplation, while Western culture is identified by dynamics where culture should fill human life with new knowledge and beauty.
In fact, the differences between two societies are quite stark. One way or another, but Western and Oriental culture enters into a certain conflict situation in contact with each other. Then the differences between cultures are worthy to study thoroughly and draw a line between the differences. Or maybe these are all false beliefs that are no longer valid in modern society?
