, leader of the rightist opposition to the KNRP Hostilities between Japan and China began with the
Marco Polo Bridge Incident on 7 July 1937. At this time, the two main Korean exile parties were the rightist
Korea Independence Party, or KIP, supported by Kim Ku, Jo So-ang, and
Chi Ch'ŏngch'ŏn and the leftist Korean National Revolutionary Party (KNRP) led by Kim Yak-san and Kim Kyu-sik. On 10 July 1937, the Chinese government invited Kim Won-bang, Kim Ku, and other Korean leaders to a conference at Lushan where the Koreans accepted an offer of large amounts of money and agreed to support a united front against Japan. In September, the Korean leaders were called again and asked to mobilize young Koreans for intelligence duties. On 1 December 1937, eighty-three young Korean men were enrolled in the particular training unit of the Shengtze Military Academy in Nanjing. The majority were from the KNRP. The Chinese government abandoned Shanghai on 8 November 1937 and Nanking on 13 December 1937. Most Koreans of both main parties followed the government in its retreat. Before this, they had formed a federation. In May 1938, there was an unsuccessful attempt to assassinate Kim Ku. The power of the right-wing nationalists declined after this until 1940. The KNRP established the
Korean Volunteer Corps as its military organization in October 1938, which, in practice, was controlled by the Chinese National Military Council. In May 1939, the two Korean leaders issued an "Open Letter to Comrades and Compatriots" in which they confessed that they had been wrong in failing to unite in the past and called on all Koreans to join. They advocated merging all the existing organizations into a single new united organization. However, their followers on the left and right resisted unification. The KIP established the
Korean Restoration Army (KRA) in September 1939, which Kim Ku wanted to keep as an independent unit, without first obtaining approval from the Chinese government. The Chinese government wanted to bring the KIP and KNRP together. When this proved difficult, from 1941 onward, they came to favor Kim Ku's KIP. In the summer of 1941, some members of the KNRP and its military arm, the Korean Volunteers Corps, moved to the
Chinese Communist Party revolutionary base area in Northwestern China. Although the Chinese Nationalist government did not consider the KNRP a radical organization, they began favoring Kim Ku's group. In the 1940s, the KNRP, whose members were generally younger and more progressive exiles, challenged the authority of the Korean Provisional Government (KPG) in
Chongqing. There were reports that Kim Ku had "accepted arrangements from the Chinese government which restricted the Korean revolutionary movement in return for a monthly subsidy." The KNRP gained support from the Chinese to form the Korean Restoration Army, which had 3,600 men in 1943. The army was held in rear areas but, to a limited extent, engaged in propaganda, intelligence, and guerrilla activities. In October 1942, two leftists were admitted to the National Council of the Provisional Government in Chongqing, Kim Kyu-sik and Chang Kon-sang. The leftists were uncooperative, and a constitutional revision was delayed until April 1944. In the following elections, the Korea Independence Party won eight seats on the council, the KNRP won four chairs, and one seat each went to the Korean People's Liberation League and an anarchist. Kim Ku remained president, Kim Kyu-sik was vice president, and Kim Won-bong was appointed Minister of Military Affairs. ==Post-war (1945–1947)==
