The Korean armed-force capability during the Second Sino-Japanese War period formed the Korean Volunteer Corps (朝鮮義勇隊), the Korea Liberation Front Youths Mission Corps(韓國光復陣線靑年工作隊), the Korean Youths War Zone Guerrilla(韓國靑年戰地工作隊), and the Korean Liberation Army(韓國光復軍) one by one in China, and performed anti-Japanese propagations and recruits through their bulletins. This research, focussing on their bulletins such as the Korean Volunteer Corps Newsletter(『朝鮮義勇隊』), the Korean Youth(『韓國靑年』), and the Liberation(『光復』), grasps Korean media’s situational understandings and responses during the Second Sino-Japanese War. The commonality among those journals was to promote Korean- Chinese anti-Japanese alliance depending on consolidation among Korean armed-force groups. Regarding the contents, the Korean Volunteer Corps Newsletter, as the corps actively participated in the anti-Japanese war, did its best for strengthening real battle capacity, for Korean-Chinese alliance, and for revolutionary struggles for the liberations of oppressed East Asian nations. The Korean Youth focussed on harassing the enemy’s rear and on culture and art activities such as recruiting and propagation. The Liberation dealt with the missions and affairs of Korean Liberation Army, the analyses of Korean independence movement, the theories, strategies, and tactics of independence movement, the accounts and analyses of China’s anti-Japanese resistances, the comprehension of Japanese empire’s situations, the disclosure of the essential cause of Japanese empire’s defeat, the postwar conception, and so on. The differences among those journals were caused by the characters and goals of each group publishing each journal, but all the journals coincided with the facts that they targeted Chinese readers, and that they tried to maximize the necessities and effects of Korean-Chinese anti-Japanese alliance. Especially, the Korean Volunteer Corps Newsletter emphasized the corps’s status as the model of Korean-Chinese anti-Japanese alliance; and the Liberation showed the Korean Liberation Army’s pride as the Provisional Government of the Republic of Korea’s only direct-controlling armed-force and as a participant of the Allied Forces. Korean medias in China thought that the longer the war lasted, the weaker Japan’s capability became, that the international aids for China made Japan’s situation more disastrous, and that Korean independence movement could get better chances if Japan propelled southern expedition in order to resolve the situation. Since the outbreak of the Pacific War, Korean medias’ interests shifted to securing the status of Provisional Government of the Republic of Korea among the Allies and to the matter of the initiative to construct an independent country. For the reason, Korean medias concentrated their propagation capabilities on the Allies’ approval for Korean Liberation Army as an official belligerent. The concrete plan was to have China approve the Korean Provisional Government first, and then to make the UK, the US, and the USSR follow China’s approval. Regarding the postwar political conception, they advocated one-party rule, in which the Provisional Government ruled by the Korea Independence Party (韓國獨立黨) should become the principal agent to construct an independent country.
