Following the March 1st Movement in 1919, Park became involved with the military training of Korean nationalists in China, but may have also engaged in anti-communist activity.

Park was born on 2 July 1881 in Cheorwon, a rural town in Gangwon province to a family with military traditions.

[3] By June 1909, and now recognized as one of the leaders of the Korean-American community, Park established a military school in Kearney, Nebraska.

[1] Syngman Rhee, by now released from prison and living in the United States, was asked to take over Park's military school, which had shifted from Kearney to Hastings, Nebraska.

Also while in Hawaii, as Park still considered that a military confrontation with Japan was likely, he established the Korean National Army Corps.

A firm believer in the use of military force to secure independence for Korea, Park Yong-man wanted more compatriots to join the National Corps.

He added that about 100 residents are finding joy in the midst of hardship by seeing the sights they saw at the Hwanghakjeong Training Center in Seoul and hearing the sounds they heard from the Three Military Branches.

(sigh)Moon Yang-mok was a person who served as a Seodang Order of Merit in Incheon in 1903 and came to Hawaii in 1905 to apply for recruitment of sugar cane workers.

In 1911, he was elected as the president of the North American Korean National Association, and the following year, he served as editor-in-chief of ‘Shinhan Minbo’.

Park gradually fell out with Syngman Rhee and others in the KNA, who favored a more diplomatic solution to Korea's annexation by Japan.

[1] The American Expeditionary Force had been dispatched to Siberia in 1918 to assist the Czechoslovak Legions in their retreat from the Bolsheviks during the Russian Civil War.

Japanese forces were also present in the region, nominally to assist in fighting the Bolsheviks, but also as part of a process to expand their influence in North East Asia.

[1] His role with the American Expeditionary Force was as an intelligence officer, and it is likely that he collected information on the communist Koreans present in Siberia at the time.

[6] It is possible that the selection of Syngman Rhee as head of the KPG was a factor in deterring Park from playing a more significant role with the organisation.

[1] Park was also involved with negotiations to form a secret mutual defense pact between the newly established KPG and the Soviets.

Park was now based in Manchuria, spending time training recruits and preparing for a military campaign against Japan.

Little is known about his activities in Manchuria, but he returned to Korea at least once, in 1924, with a group of military and business leaders of the pro-Japanese Chinese government.

[3] Park, now under suspicion of collaborating with the Japanese against communism due to his activities in Siberia and Manchuria, was assassinated in Beijing on 17 October 1928 by a Korean communist, Lee Hae-young.
