Modernism has been formed as an opposition against Rationalism in the end of 19th century and a existing tradition and conventionality through the history of Western civilization that is the birthplace. However, Modernism in both countries took on a special aspect with a combination of the general aspect of the western literary and her own aspect and has been accepted by the unique cultural environment of Korea and China only over a decade, while the most trends of western literature that had formed and developed for many centuries. Modernism in the world of poetry of both countries could not but have an aspect different from western Modernism due to refraction that it has to be undergone by the main agent through the process of the acceptance. In Korea, Modernism has a refracted form in accordance with the characteristic of Japanese culture because most intellectuals in Korea didn`t accept it directly, but they did it when they studied in Japan as the children the middle class in colony. For example, `Anglo-American Modernism` is called `intellectualism` which means philosophy in Korea due to the japanese effect. However, in china, they showed a different aspect from Korea because a lot of students went to Europe and U.S.A. to study and they experienced their trend of literature directly. It minimized the refraction of the trend of western literature. On the other hand, Modernism leaned toward Symbolism but were indifferent to Futuristic relatively in the world of poetry of China because contemporary writers in China had a distance from their mental mechanism against Futuristic literature that denied traditional art and thought throughly that human being had made. The point that we have to investigate and reveal the truth carefully is we shouldn`t have to be based on and judge the western Modernism because Modernism of the both countries has a different cultural environment from the western one. Modernism has developed with a clear classification, Anglo-American Modernism and European Modernism in western, but there is no border in Korea and China. The contemporary poets in Korea and China had developed and produced their own Korean and Chinese Modernism that are mixed their wandering, disillusionment, and ideal under the gloomy political reality and western Modernism, symbolism, and traditional philosophy and literature. In other words, Modernism in the world of poetry of Korea and China does not correspond with the western one, but they have their own characteristic through the process of acceptance in their ways.
