On 3 March, the KPO planned a mission but did not execute it. After the
January 28 incident between China and Japan, Kim developed a plan to use Korean laborers to sabotage Japanese airplane hangars and ammunition dumps with explosives. However, China was defeated before the mission began. In April 1932, members Yu Chin-sik () and Yi Dŏk-chu () were sent to Korea to assassinate Japanese
Governor-General of Korea Kazushige Ugaki. On 26 May 1932, the KPO failed another mission. The targets were
Kwantung Army general
Honjō Shigeru, Japanese Foreign Minister and President of the
South Manchuria Railway company
Uchida Kōsai, and
Kwantung Governor Mannosuke Yamaoka. The targets were going to appear at
Dalian station on 26 May at 7:40 pm, for a meeting with delegates from the
League of Nations. Kim dispatched members Ch'oe Heung-sik in late March and Yu Sang-kŭn on 27 April to Dalian, in Manchuria. Kim dispatched Ch'oe a month earlier than Yu, in order to have him scope out the area before the attack. Yu, carrying weapons and a canteen bomb, similar to a bomb used by Yun at Hongkou Park, arrived at Dalian on 4 May. However, a telegram they had sent at the Dalian post office days prior was intercepted by the Japanese. Ch'oe was found in his hideout, tortured for the whereabouts of Yu, and executed. Yu was caught on 25 May, sentenced to life imprisonment, and died on 14 August 1945, a day before the liberation of Korea. == Aftermath ==
