The first published description of a Tungusic people to reach beyond Russia into the rest of Europe was by the Dutch traveler Isaac Massa in 1612, who passed along information from Russian reports after his stay in Moscow.  - Siberia is an extensive geographical region, and by the broadest definition is also known as North Asia.

European Russia contains about 77% of the country's population (110,000,000 people out of about 144,000,000) in an area comprising almost 4 million km (1.54 million mi); an average of 27.5 persons per km (70 per mi). This territory makes up 38% of Europe. Its eastern border is defined by the Ural Mountains and in the south, it is defined by the border with Kazakhstan. This area includes Moscow and Saint Petersburg, the two largest cities in Russia.  - The Tungusic languages (also known as Manchu-Tungus, Tungus) form a language family spoken in Eastern Siberia and northeast China by Tungusic peoples. Many Tungusic languages are endangered, and the long-term future of the family is uncertain. There are approximately 75,000 native speakers of the dozen living languages of the Tungusic language family. Some linguists consider Tungusic to be part of the contentious Altaic language family, along with Turkic, Mongolic, and sometimes Koreanic and Japonic. However, Altaic is not a linguistically genetic group. If the Altaic family exist it would be a sprachbund.  - Russia (from the  Rus'), also officially known as the Russian Federation, is a country in Eurasia.

To the east and southeast, Europe is generally considered as separated from Asia by the watershed divides of the Ural and Caucasus Mountains, the Ural River, the Caspian and Black Seas, and the waterways of the Turkish Straits. Yet the non-oceanic borders of Europea concept dating back to classical antiquityare arbitrary. The primarily physiographic term "continent" as applied to Europe also incorporates cultural and political elements whose discontinuities are not always reflected by the continent's current overland boundaries.  - Eurasia is the combined continental landmass of Europe and Asia. The term is a portmanteau of its constituent continents. Located primarily in the Northern and Eastern Hemispheres, it is bordered by the Atlantic Ocean to the west, the Pacific Ocean to the east, the Arctic Ocean to the north, and by Africa, the Mediterranean Sea, and the Indian Ocean to the south. The division between Europe and Asia as two different continents is a historical and cultural construct, with no clear physical separation between them; thus, in some parts of the world, Eurasia is recognized as the largest of five or six continents. In geology, Eurasia is often considered as a single rigid megablock. However, the rigidity of Eurasia is debated based on the paleomagnet data.  - China, officially the People's Republic of China (PRC), is a unitary sovereign state in East Asia.
