Russia is the largest country in the world, covering over 17,125,191 km2 (6,612,073 sq mi), and encompassing more than one-eighth of Earth's inhabited land area. Russia extends across eleven time zones, and has the most borders of any country in the world, with sixteen sovereign nations.
Manchuria is a term that refers to a region in northeast Asia encompassing the entirety of present-day northeast China, and historically parts of the modern-day Russian Far East, often referred to as Outer Manchuria. Its definition may refer to varying geographical extents as follows: in the narrow sense, the area constituted by three Chinese provinces of Heilongjiang, Jilin, and Liaoning but broadly also including the eastern Inner Mongolian prefectures of Hulunbuir, Hinggan, Tongliao, and Chifeng, collectively known as Northeast China; in a broader sense, the area of historical Manchuria includes the aforementioned regions plus the Amur river basin, parts of which were ceded to the Russian Empire by the Manchu-led Qing dynasty during the Amur Annexation of 1858–1860. The parts of Manchuria ceded to Russia are collectively known as Outer Manchuria or Russian Manchuria, which include present-day Amur Oblast, Primorsky Krai, the Jewish Autonomous Oblast, the southern part of Khabarovsk Krai, and the eastern edge of Zabaykalsky Krai.
The Trans-Siberian Railway, historically known as the Great Siberian Route and often shortened to Transsib, is a large railway system that connects European Russia to the Russian Far East. Spanning a length of over 9,289 kilometers, it is the longest railway line in the world. It runs from the city of Moscow in the west to the city of Vladivostok in the east.
The Russian Far East is a region in North Asia. It is the easternmost part of Russia and the Asian continent, and is coextensive with the Far Eastern Federal District, which encompasses the area between Lake Baikal and the Pacific Ocean. The area's largest city is Khabarovsk, followed by Vladivostok. The region shares land borders with the countries of Mongolia, China, and North Korea to its south, as well as maritime boundaries with Japan to its southeast, and with the United States along the Bering Strait to its northeast.
The Soviet Union incorporated an area of over 22,402,200 square kilometres (8,649,500 sq mi), covering approximately one-sixth of Earth's land surface. It spanned most of Eurasia. Its largest and most populous republic was the Russian SFSR which covered roughly three-quarters of the surface area of the union, including the complete territory of contemporary Russia.
The Far Eastern Republic, sometimes called the Chita Republic, was a nominally independent state that existed from April 1920 to November 1922 in the easternmost part of the Russian Far East. Although nominally independent, it largely came under the control of the Russian Soviet Federative Socialist Republic (RSFSR), which envisaged it as a buffer state between the RSFSR and the territories occupied by Japan during the Russian Civil War of 1917–1922. Its first president was Alexander Krasnoshchyokov.
Manchuria is a region in East Asia. Depending on the definition of its extent, Manchuria can refer either to a region falling entirely within present-day China, or to a larger region today divided between Northeast China and the Russian Far East. To differentiate between the two parts following the latter definition, the Russian part is also known as Outer Manchuria, while the Chinese part is known as Northeast China.
Outer Manchuria, sometimes called Russian Manchuria, refers to a region in Northeast Asia that is now part of the Russian Far East but historically formed part of Manchuria. While Manchuria now more normatively refers to Northeast China, it originally included areas consisting of Priamurye between the left bank of Amur River and the Stanovoy Range to the north, and Primorskaya which covered the area in the right bank of both Ussuri River and the lower Amur River to the Pacific Coast. The region was ruled by a series of Chinese dynasties and the Mongol Empire, but control of the area was ceded to the Russian Empire by Qing China during the Amur Annexation in the 1858 Treaty of Aigun and 1860 Treaty of Peking, with the terms "Outer Manchuria" and "Russian Manchuria" arising after the Russian annexation.
A subregion is a part of a larger geographical region or continent. Cardinal directions are commonly used to define subregions. There are many criteria for creating systems of subregions; this article is focusing on the United Nations geoscheme, which is a changing, constantly updated, UN tool based on specific political geography and demography considerations relevant in UN statistics.
Northeast China is a region of the People's Republic of China. It consists of three provinces, namely Liaoning, Jilin, and Heilongjiang.
The Ussuri or Wusuli is a river that runs through Khabarovsk and Primorsky Krais, Russia and the southeast region of Northeast China. It rises in the Sikhote-Alin mountain range, flowing north and forming part of the Sino-Russian border, until it joins the Amur as a tributary to it near Khabarovsk. It is approximately 897 km (557 mi) long. The Ussuri drains the Ussuri basin, which covers 193,000 km2 (75,000 sq mi). Its waters come from rain (60%), snow (30–35%), and subterranean springs. The average discharge is 1,620 m3/s (57,000 cu ft/s), and the average elevation is 1,682 metres (5,518 ft).
Grigory Mikhaylovich Semyonov, or Semenov, was a Japanese-supported leader of the White movement in Transbaikal and beyond from December 1917 to November 1920, a lieutenant general, and the ataman of Baikal Cossacks (1919). He was the commander of the Far Eastern Army during the Russian Civil War. He was also a prominent figure in the White Terror. U.S. Army intelligence estimated that he was responsible for executing 30,000 people in one year.
The Soviet invasion of Manchuria, formally known as the Manchurian Strategic Offensive Operation or simply the Manchurian Operation and sometimes Operation August Storm, began on 9 August 1945 with the Soviet invasion of the Japanese puppet state of Manchukuo, which was situated in Japanese-occupied Manchuria. 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.

The Soviet–Japanese War was a campaign of the Second World War that began with the Soviet invasion of Manchuria following the Soviet declaration of war against Japan on 8 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.
East Asia is a geographical and cultural region of Asia including China, Japan, Mongolia, North Korea, South Korea, and Taiwan. Additionally, Hong Kong and Macau are the two special administrative regions of China. The economies of China, Japan, South Korea, and Taiwan are among the world's largest and most prosperous. East Asia borders North Asia to the north, Southeast Asia to the south, South Asia to the southwest, and Central Asia to the west. To its east is the Pacific Ocean.
The Khorchin are a subgroup of the Mongols that speak the Khorchin dialect of Mongolian and predominantly live in northeastern Inner Mongolia of China.
Hokushin-ron was a political doctrine of the Empire of Japan before World War II that stated that Manchuria and Siberia were Japan's sphere of interest and that the potential value to Japan for economic and territorial expansion in those areas was greater than elsewhere. Its supporters were sometimes called the Strike North Group.
Kantokuen was an operational plan created by the General Staff of the Imperial Japanese Army for an invasion and occupation of the Russian Far East, capitalizing on the outbreak of the Soviet–German War in June 1941. Involving seven Japanese armies and a major portion of the empire's naval and air forces, it would have been the largest combined arms operation in Japanese history up to that point, and one of the largest of all time.
