The purpose of this study is to generate wide-ranging discussion on modern Korean try and explore b suggestions by investigating ``reflection of Southeast Asia`` and ``poetic consideration on Southeast Asia`` in modern Korean poetry including North Korean poetry. Southeast Asia has appeared in micro Korean poetry since 1941 when Japan waged the Pacific War against U.S. and when Korea had been colonized by Japan for about 30 years. Therefore, most of the poetic works in this period are pro-Japanese, which is directly related to deformed modernity that Korea and the Southeast Asian countries experienced. The regional history of Southeast Asia can be divided into 3 periods: (1) a period when western imperialism was replaced by Japanese colonialism during the Pacific War, (2) a period when western imperialism was restored, and (3) a period when Southeast Asian countries achieved independence from 1945 to the late 1950s. Following the periods, the poetic relation between Korea and Southeast were intricately developed The Korean poetry created during the (2) and (3) periods shows strong solidarity kit small and powerless Southeast Asian countries that had suffered from political and economic pressure. The historical experience of Korea`s participation in the Vietnam War made South Korean poetry extended spatially and diversified qualitatively. It should be noted that as the number of migrant workers and .women married to Korean men from Southeast Asian countries has increased since the mid l990s poetic works dealing with their lives have been produced.
