Manchukuo was a puppet state of the Empire of Japan in Northeast China that existed from 1932 until its dissolution in 1945. It was ostensibly founded as a republic, its territory consisting of the lands seized in the Japanese invasion of Manchuria; it was later declared to be a constitutional monarchy in 1934, though very little changed in the actual functioning of government. Manchukuo received limited diplomatic recognition, mostly from states aligned with the Axis powers, with its existence widely seen as illegitimate.
The Potsdam Declaration, or the Proclamation Defining Terms for Japanese Surrender, was a statement that called for the surrender of all Japanese armed forces during World War II. On July 26, 1945, United States President Harry S. Truman, United Kingdom Prime Minister Winston Churchill, and Chairman of China Chiang Kai-shek issued the document, which outlined the terms of surrender for the Empire of Japan, as agreed upon at the Potsdam Conference. The ultimatum stated that, if Japan did not surrender, it would face "prompt and utter destruction."
The Yalta Conference, held 4–11 February 1945, was the World War II meeting of the heads of government of the United States, the United Kingdom and the Soviet Union to discuss the postwar reorganization of Germany and Europe. The three states were represented by President Franklin D. Roosevelt, Prime Minister Winston Churchill, and General Secretary Joseph Stalin. The conference was held near Yalta in Crimea, Soviet Union, within the Livadia, Yusupov, and Vorontsov palaces.
The Soviet–Japanese Neutrality Pact, also known as the Japanese–Soviet Non-aggression Pact, was a non-aggression pact between the Soviet Union and the Empire of Japan signed on April 13, 1941, two years after the conclusion of the Soviet-Japanese Border War. The agreement meant that for most of World War II, the two nations fought against each other's allies but not against each other. In 1945, late in the war, the Soviets scrapped the pact and joined the Allied campaign against Japan.
The Soviet invasion of Manchuria, formally known as the Manchurian Strategic Offensive Operation or simply the Manchurian Operation, began on 9 August 1945 with the Soviet invasion of the Japanese puppet state of Manchukuo. It was the largest campaign of the 1945 Soviet–Japanese War, which resumed hostilities between the Union of Soviet Socialist Republics and the Empire of Japan after almost six years of peace. Since 1983, the operation has sometimes been called Operation August Storm after U.S. Army historian David Glantz used this title for a paper on the subject.
The United Nations General Assembly Resolution 505 is titled Threats to the political independence and territorial integrity of China and to the peace of the Far East, resulting from Soviet violations of the Sino-Soviet Treaty of Friendship and Alliance of August 14, 1945 and from Soviet violations of the Charter of the United Nations. The UN General Assembly adopted this resolution on 1 February 1952 during its sixth session after the Republic of China complained to the United Nations against the Soviet Union.
The Allies, formally referred to as the United Nations from 1942, were an international military coalition formed during World War II (1939–1945) to oppose the Axis powers. Its principal members by the end of 1941 were the "Big Four" – United Kingdom, United States, Soviet Union, and China.
The surrender of the Empire of Japan in World War II was announced by Emperor Hirohito on 15 August and formally signed on 2 September 1945, bringing the war's hostilities to a close. By the end of July 1945, the Imperial Japanese Navy (IJN) had become incapable of conducting major operations and an Allied invasion of Japan was imminent. Together with the United Kingdom and China, the United States called for the unconditional surrender of the Japanese armed forces in the Potsdam Declaration on 26 July 1945—the alternative being "prompt and utter destruction". While publicly stating their intent to fight on to the bitter end, Japan's leaders were privately making entreaties to the publicly neutral Soviet Union to mediate peace on terms more favorable to the Japanese. While maintaining a sufficient level of diplomatic engagement with the Japanese to give them the impression they might be willing to mediate, the Soviets were covertly preparing to attack Japanese forces in Manchuria and Korea in fulfillment of promises they had secretly made to the United States and the United Kingdom at the Tehran and Yalta Conferences.
The Soviet–Japanese War, known in Mongolia as the Liberation War of 1945, was a campaign of the Second World War that began with the Soviet invasion of Japanese-occupied territory following the Soviet declaration of war against Japan on 7 August 1945. The Soviet Union and Mongolian People's Republic toppled the Japanese puppet states of Manchukuo in Manchuria and Mengjiang in Inner Mongolia, as well as northern Korea, Karafuto on the island of Sakhalin, and the Kuril Islands. The defeat of Japan's Kwantung Army helped bring about the Japanese surrender and the end 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 was made apparent that the Soviet Union was not willing to act as a third party in negotiating an end to hostilities on conditional terms.
Zhang Jinghui ; was a Chinese general, warlord and politician during the Warlord era. He is noted for his role in the Japanese puppet regime of Manchukuo in which he served as Prime Minister for most of its existence.
Sino-Soviet relations, or China–Soviet Union relations, refers to the diplomatic relationship between China and the various forms of Soviet Power which emerged from the Russian Revolution of 1917 to 1991, when the Soviet Union ceased to exist.
The Empire of Japan's Kwantung Army invaded Manchuria on 18 September 1931, immediately following the Mukden Incident. At the war's end in February 1932, the Japanese established the puppet state of Manchukuo. Their occupation lasted until the success of the Soviet Union and Mongolia with the Manchurian Strategic Offensive Operation in mid-August 1945, towards the end of the Second World War.
The Soviet–Japanese border conflicts, also known as the Soviet-Japanese Border War, the First Soviet-Japanese War, the Russo-Mongolian-Japanese Border Wars or the Soviet-Mongolian-Japanese Border Wars, were a series of minor and major conflicts fought between the Soviet Union, Mongolia and Japan in Northeast Asia from 1932 to 1939.
During World War II, the Soviet Union occupied and annexed several countries effectively handed over by Nazi Germany in the secret Molotov–Ribbentrop Pact of 1939. These included the eastern regions of Poland, as well as Latvia, Estonia, Lithuania, part of eastern Finland and eastern Romania. Apart from the Molotov–Ribbentrop Pact and post-war division of Germany, the USSR also occupied and annexed Carpathian Ruthenia from Czechoslovakia in 1945.
The First Area Army was a field army of the Imperial Japanese Army during World War II, based in northern Manchukuo and active in combat against the Soviet Union in the closing stages of the war.
The territorial conquests of the Empire of Japan in the Western Pacific Ocean and East Asia began in 1895 with its victory over Qing China in the First Sino-Japanese War. Subsequent victories over the Russian Empire and German Empire expanded Japanese rule to Taiwan, Korea, Micronesia, southern Sakhalin, several concessions in China, and the South Manchuria Railway. In 1931, Japan invaded Manchuria, resulting in the establishment of the puppet state of Manchukuo the following year; thereafter, Japan adopted a policy of founding and supporting puppet states in conquered regions. These conquered territories became the basis for the Greater East Asia Co-Prosperity Sphere in 1940.
The Kwantung Army was a general army of the Imperial Japanese Army from 1919 to 1945.
Japan during World War II refers to the history of the Empire of Japan during World War II. This includes the invasion of the Republic of China, the annexation of French Indochina and the subsequent invasion of British India, the Pacific War and the Surrender of Japan.
Soviet involvement in regime change entailed both overt and covert actions aimed at altering, replacing, or preserving foreign governments. In the 1920s, the nascent Soviet Union intervened in multiple governments primarily in Asia, acquiring the territory of Tuva and making Mongolia into a satellite state. During World War II, the Soviet Union helped overthrow many puppet regimes of Nazi Germany and the Empire of Japan, including in East Asia and much of Europe. Soviet forces were also instrumental in ending the rule of Adolf Hitler over Germany.
During the Soviet–Japanese War in August 1945, the Soviet Union made plans to invade Hokkaido, the northernmost of Japan's four main home islands. Opposition from the United States and doubts within the Soviet high command caused the plans to be canceled before the invasion could begin.
