After the outbreak of World War II, Japan continued its military conquest of Asia. It invaded and annexed Indochina into its
Greater East Asia Co-Prosperity Sphere in 1940–1941. As France had fallen to
Nazi Germany, the colonial administration in Vietnam of Admiral
Jean Decoux was loyal to the Axis collaborationist
Vichy France of Marshal
Philippe Pétain. As Vichy France was nominally allied to Japan, the French administration was left in charge of the day-to-day affairs of French Indochina, with the Japanese overseeing them. . Photo by

In the early 20th century, Japan was also seen by many Vietnamese as a promoter of Asian nationalism, and many Vietnamese nationalists had traveled to Japan in an attempt to further the Vietnamese independence movement. Kim was approached by several Japanese experts in Vietnamese studies. The contacts and his ties to a progressive organisation in Hanoi made Kim politically suspect to the Decoux administration. When Decoux implemented his second major purge of pro-Japanese Vietnamese in the autumn of 1943, Kim was reported to be on the list of the
Sûreté (Criminal Investigation Department). On October 28, 1943, Japanese agents escorted Kim to the
Kenpeitai (military police) office in Hanoi and put him under protection. There, Kim was joined by Dương Bá Trạc, a co-editor on a dictionary that was currently being written. According to Kim's account, Trạc persuaded him to co-sign a letter applying for an evacuation to
Singapore. At the beginning of November, the Japanese escorted them to
Saigon. After briefly living at the Kenpeitai office, they became the guests of Dainan Kōshi, a Japanese business firm owned by Matsushita Mitsuhiro, which was known as a front for intelligence operations. By now, the
Liberation of Paris in August 1944 and the fall of Vichy France meant that Japan could no longer depend on the French colonial administration to co-operate. As a result,
they assumed direct control of Indochina by deposing the French in a coup on March 9 and declared Vietnam to be independent under the newly created
Empire of Vietnam with
Bảo Đại, Vietnam's titular monarch, as its head of state. Japan however, maintained military control. Bảo Đại was then charged with selecting a prime minister and a cabinet. It was believed that Bảo Đại sent a message to
Ngô Đình Diệm, who was then living under Japanese protection in
Saigon, in asking him to form a government. However, the message never arrived, which was put down to Japanese concerns that Diệm would seek to govern independently, rather than toe the Japanese line. Arriving in Saigon, he met with General Saburo Kawamura, Chief of Staff of the
Japanese Indochina Garrison Army and Lieutenant Colonel Hayashi Hidezumi, Kawamura's chief of political affairs. Kawamura told Kim that he was one of the "notables" invited by Emperor Bảo Đại to consult in
Huế on the creation of the new independent government. During this time, Kim also met with Diệm for the first time, finding out that he had not been included on the Japanese shortlist. According to his own account, Kim accepted the invitation to talk with Bảo Đại because
Hoàng Xuân Hãn, a young friend, was also on the emperor's list. Kim departed Saigon on April 2 and arrived in Huế three days later. ==Rule==
