Several notable waves of Han Chinese immigration to Jiangsu, Zhejiang, Guangdong and Fujian took place during the collapse of the Jin, the Tang, and the Song. Some nomadic groups succeeded in conquering the whole territory of China, establishing dynasties such as the Yuan (Mongol) and Qing (Manchu). Each time, they also brought new elements into Chinese culture - for instance, military uniform, the qipao and the pigtail, the latter of which was deeply resented by the Han Chinese. A new age (1500 A.D. - Present) While China achieved many things in the First millennium and early 2nd millennium, it became an isolationist country in the 15th century C.E. This was because Spain found enormous silver in the new continent, which was the main currency (money) in China and Europe at the time, and China did not want to be bought by the foreigners. By the time of the Renaissance, European powers started to take over other countries in Asia. While China was never actually taken over, many European countries, such as Britain and France built spheres of influence in China.

In geopolitics, the concepts of geography and territory are reduced to the fundamental aspects of relations between States, they serve as a basic method of interpreting the past, they act as the main factors of human existence, organizing all other aspects of existence around them. It is in this perspective that the article examines the attitude to Baikal in the history of the mutually linked foreign policy of Russia and China. It is noted that the Mongols and Manchus, who once conquered China, not only found themselves largely assimilated by the defeated society, but over time, a large part of their ancestral territories began to be perceived as native Chinese. Far from being justified, this also applied to Baikal, although the Yakut etymology of its name, associated with the ethnic ancestors of the Yakuts — the Huns, has been clearly traced since ancient times. Since ancient times, Buryats and Evenks who voluntarily became part of Russia have lived around Baikal. Modern development is characterized by the “penetration” of the Chinese into the business of Asian Russia. In the Baikal region, this focus has basically three goals: forest, clean water, and ownership of land and other natural resources. In a special row, it is necessary to put projects for supplying the population of some Chinese territories with Baikal water, which is planned to be transported both in bottled form and in the future through pipes.
