Context_2 : The Soviet–Japanese War (Russian: Советско-японская война ; Japanese: ソ連対日参戦 , "Soviet Union entry into war against Japan") was a military conflict within the Second World War beginning soon after midnight on August 9, 1945, with the Soviet invasion of the Japanese puppet state of Manchukuo. The Soviets and Mongolians terminated Japanese control of Manchukuo, Mengjiang (Inner Mongolia), northern Korea, Karafuto, and the Chishima Islands. The defeat of Japan's Kwantung Army helped in the Japanese surrender and the termination of World War II. The Soviet entry into the war was a significant factor in the Japanese government's decision to surrender unconditionally, as it made apparent the Soviet Union would no longer be willing to act as a third party in negotiating an end to hostilities on conditional terms. Context_3 : Japanese language education in Vietnam first became widespread during the Empire of Vietnam, which was set up as a puppet state after Japan's 1941 World War II invasion of French Indochina. However, after Japan's 1945 surrender and withdrawal from Vietnam, there was little further education in the language until the 1970s. A 2006 survey showed 1,037 teachers teaching 29,982 students at 110 different institutions, an increase of 66% in the number of students since the previous year's survey. Context_4 : The State of Burma (Burmese: ဗမာ ) was a puppet state of the Empire of Japan, created in 1943 during the Japanese occupation of Burma in World War II. Context_5 : Mengjiang (Mengkiang; ; Hepburn: Mōkyō), also known in English as Mongol Border Land or the Mongol United Autonomous Government, was an autonomous area in Inner Mongolia, existing as a puppet state of the Empire of Japan under nominal Chinese sovereignty. Formed in 1939, it consisted of the then-Chinese provinces of Chahar and Suiyuan, corresponding to the central part of modern Inner Mongolia. It is occasionally called Mengguguo (or Mengkukuo; ) (in analogy to Manchukuo, another Japanese puppet state in Manchuria). The capital was Kalgan, and the ruler was Demchugdongrub. Context_6 : A puppet ruler is a person who has a title indicating possession of political power, but who, in reality, is controlled by outside individuals or forces. Such outside power can be exercised by a foreign government, in which case the puppet ruler's domain is called a puppet state. But the puppet ruler may also be controlled by internal forces, such as non-elected officials. Context_7 : Manchukuo (: "Mǎnzhōuguó"literally: " State of Manchuria" ) was a puppet state in Northeast China and Inner Mongolia, which was governed under a form of constitutional monarchy. The area, collectively known as Manchuria by westerners and Japanese, was designated by China's erstwhile Qing Dynasty as the "homeland" of the ruling family's ethnic group, the Manchus. In 1931, the region was seized by Japan following the Mukden Incident and a pro-Japanese government was installed one year later with Puyi, the last Qing emperor, as the nominal regent and emperor. Manchukuo's government was abolished in 1945 after the defeat of Imperial Japan at the end of World War II. The territories formally claimed by the puppet state were first seized in the Soviet invasion of Manchuria in August 1945, and then formally transferred to Chinese administration in the following year.

It is classified as a AAAAA scenic area by the China National Tourism Administration. Context_9 : The Territory of the Military Commander in Serbia (German: "Gebiet des Militärbefehlshabers in Serbien" ) was the area of the Kingdom of Yugoslavia that was placed under a military government of occupation by the Wehrmacht following the invasion, occupation and dismantling of Yugoslavia in April 1941. The territory included only central Serbia, with the addition of the northern part of Kosovo (around Kosovska Mitrovica), and the Banat. This territory was the only area of partitioned Yugoslavia in which the German occupants established a military government. This was due to the key rail and riverine transport routes that passed through it, and its valuable resources, particularly non-ferrous metals. On 22 April 1941, the territory was placed under the supreme authority of the German military commander in Serbia, with the day-to-day administration of the territory under the control of the chief of the military administration staff. The lines of command and control in the occupied territory were never unified, and were made more complex by the appointment of direct representatives of senior Nazi figures such as "Reichsführer-SS" Heinrich Himmler (for police and security matters), "Reichsmarschall" Hermann Göring (for the economy), and "Reichsminister" Joachim von Ribbentrop (for foreign affairs). The Germans used Bulgarian troops to assist in the occupation, but they were at all times under German control. Sources variously describe the territory as a puppet state, a protectorate, a "special administrative province", or describe it as having a puppet government. The military commander in Serbia had very limited German garrison troops and police detachments to maintain order, but could request assistance from a corps of three divisions of poorly-equipped occupation troops.
