Far Eastern Federal District in the context of "North Asia"

The Russian Far East (Russian: Дальний Восток России, IPA: [ˈdalʲnʲɪj vɐˈstok rɐˈsʲiɪ]) 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.

Although foreign sources often consider the Russian Far East to be a part of Siberia, it has been historically categorized separately from Siberia in Russian regional schemes (and previously during the Soviet era when it was called the Soviet Far East).

Siberia (/saɪˈbɪəriə/ sy-BEER-ee-ə; Russian: Сибирь, romanized: Sibir', IPA: [sʲɪˈbʲirʲ] ), also known as Asian Russia, is an extensive geographical region comprising all of North Asia, from the Ural Mountains in the west to the Pacific Ocean in the east. It has formed a part of the sovereign territory of Russia and its predecessor states since the lengthy conquest of Siberia, which began with the fall of the Khanate of Sibir in 1582 and concluded with the annexation of Chukotka in 1778. Siberia is vast and sparsely populated, covering an area of over 13.1 million square kilometres (5,100,000 sq mi) – about three-quarters of Russia's total area, but home to roughly a quarter of Russia's population. Novosibirsk, Krasnoyarsk, and Omsk are the largest cities in the area.

Because Siberia is a geographic and historic concept and not a political entity, there is no single precise definition of its territorial borders. Traditionally, Siberia spans the entire expanse of land from the Ural Mountains to the Pacific Ocean, with the Ural River usually forming the southernmost portion of its western boundary, and includes most of the drainage basin of the Arctic Ocean. It is further defined as stretching from the territories within the Arctic Circle in the north to the northern borders of Kazakhstan, Mongolia, and China in the south, although the hills of north-central Kazakhstan are also commonly included. The Russian government divides the region into three federal districts (groupings of Russian federal subjects), of which only the central one is officially referred to as "Siberian"; the other two are the Ural and Far Eastern federal districts, named for the Ural and Russian Far East regions that correspond respectively to the western and eastern thirds of Siberia in the broader sense.

Buryatia, officially the Republic of Buryatia, is a republic of Russia located in the Russian Far East. Formerly part of the Siberian Federal District, it has been administered as part of the Far Eastern Federal District since 2018. To its north lie Irkutsk Oblast and Lake Baikal, the deepest lake in the world; Zabaykalsky Krai to the east; Tuva to the west and Mongolia to the south. Its capital is the city of Ulan-Ude. It has an area of 351,300 square kilometers (135,600 sq mi) with a population of 978,588 (2021 Census). It is home to the indigenous Buryats.

The Siberian Federal District (Russian: Сибирский федеральный округ, IPA: [sʲɪˈbʲirskʲɪj fʲɪdʲɪˈralʲnɨj ˈokrʊk]) is one of the eight federal districts of Russia. Its population was 17,178,298 according to the 2010 Census, living in an area of 4,361,800 square kilometers (1,684,100 sq mi). The entire federal district lies within the continent of Asia.

The district was created by presidential decree on 13 May 2000 and covers around 30% of the total land area of Russia. In November 2018, Buryatia and Zabaykalsky Krai were removed from the Siberian Federal District and added to the Far Eastern Federal District in accordance with a decree issued by Russian President Vladimir Putin.

Khabarovsk Krai (Russian: Хабаровский край, romanized: Khabarovskiy kray, IPA: [xɐˈbarəfskʲɪj kraj]) is a federal subject (a krai) of Russia. It is located in the Russian Far East and is administratively part of the Far Eastern Federal District. The administrative centre of the krai is the city of Khabarovsk, which is home to roughly half of the krai's population and the largest city in the Russian Far East (just ahead of Vladivostok). Khabarovsk Krai is the third-largest federal subject by area, and had a population of 1,343,869 as of 2010.

Being dominated by the Siberian High winter cold, the continental climates of the krai see extreme freezing for an area adjacent to the sea near the mid-latitudes, but also warm summers in the interior. The southern region lies mostly in the basin of the lower Amur River, with the mouth of the river located at Nikolaevsk-on-Amur draining into the Strait of Tartary, which separates Khabarovsk Krai from the island of Sakhalin. The north occupies a vast mountainous area along the coastline of the Sea of Okhotsk, a marginal sea of the Pacific Ocean. Khabarovsk Krai is bordered by Magadan Oblast to the north; Amur Oblast, Jewish Autonomous Oblast, and the Sakha Republic to the west; Primorsky Krai to the south; and Sakhalin Oblast to the east.

Khabarovsk (Russian: Хабаровск [xɐˈbarəfsk] ) is the largest city and the administrative centre of Khabarovsk Krai, Russia, located 30 kilometers (19 mi) from the China–Russia border, at the confluence of the Amur and Ussuri Rivers, about 800 kilometers (500 mi) north of Vladivostok. As of the 2021 Russian census, it had a population of 617,441. It was known as Khabarovka until 1893.

The city was the administrative center of the Far Eastern Federal District of Russia from 2002 until December 2018, when the status was given to Vladivostok. As is typical of the interior of the Russian Far East, Khabarovsk has an extreme climate with strong seasonal swings resulting in strong, cold winters and relatively hot and humid summers.

Vladivostok (/ˌvlædɪˈvɒstɒk/ VLAD-iv-OST-ok; Russian: Владивосток, lit. '"Ruler of the East"', IPA: [vlədʲɪvɐˈstok] ) is the largest city and the administrative center of Primorsky Krai and the capital of the Far Eastern Federal District of Russia. It is located around the Golden Horn Bay on the Sea of Japan, covering an area of 331.16 square kilometers (127.86 square miles), with a population of 603,519 residents as of 2021. Vladivostok is the second-largest city in the Far Eastern Federal District, as well as the Russian Far East, after Khabarovsk. It is located approximately 45 kilometers (28 mi) from the China–Russia border and 134 kilometers (83 mi) from the North Korea–Russia border.

Vladivostok was historically part of Outer Manchuria. Shortly after the signing of the Treaty of Aigun between Qing China and the Russian Empire and affirmed by the Convention of Peking – from which it is also known as the Amur Annexation – the city was founded as a Russian military outpost on July 2, 1860. In 1872, the main Russian naval base on the Pacific Ocean was transferred to the city, stimulating its growth. In 1914 the city experienced rapid growth economically and ethnically diverse with population exceeding over 100,000 inhabitants with slightly less than half of the population being Russians. During this time, large Asian communities developed in the city. The public life of the city flourished; many public associations were created, from charities to hobby groups. After the outbreak of the Russian Revolution in 1917, Vladivostok was occupied in 1918 by White Russian and Allied forces, the last of whom, from the Japanese Empire, were not withdrawn until 1922 as part of its wider intervention in Siberia; by that time the antirevolutionary White Army forces had collapsed. That same year, the Red Army occupied the city, absorbing the Far Eastern Republic into the Russian Soviet Federative Socialist Republic. Following the dissolution of the Soviet Union in 1991, the city became a part of the Russian Federation.

Kamchatka Krai (Russian: Камча́тский край, romanized: Kamchatskiy kray, IPA: [kɐmˈtɕatskʲɪj kraj]) is a federal subject of Russia (a krai), situated in the Russian Far East. It is administratively part of the Far Eastern Federal District. Its administrative center and largest city is Petropavlovsk-Kamchatsky, home to over half of its population of 291,705 (2021 census).

Kamchatka Krai was formed on 1 July 2007, as a result of the merger of Kamchatka Oblast and Koryak Autonomous Okrug, based on the voting in a referendum on the issue on 23 October 2005. The okrug retains the status of a special administrative division of the krai, under the name of Koryak Okrug.
