What do you mean the Yuan Dynasty belonged to China? China's concept came into being very late. The concept of state in the modern sense is due to the rise of national independence, but China didn't use the word China for the first time until after the jaxa War in the Qing Dynasty, and it is still different from the current "China". The concept that China is now a sovereign country did not exist before-it did not appear until 19 and the 20th century.

In the history of China, the Yuan Dynasty was brought in because it was completely assimilated by the Central Plains culture, and a large number of Mongolians migrated to the Central Plains, even to the south of China. This kind of integration cannot be fooled by colonization. After the formation of a modern national sovereign state, it is natural to regard this period of history as the process of Mongolians joining the Chinese nation, so there is no saying that the Yuan Dynasty colonized China. And his capital is Beijing, and the destination of all countries that come to Korea is Beijing. Did Britain colonize India and set the country in India? If Britain moved its capital to India and made Delhi its capital on a large scale before the industrial revolution, it is not surprising that India and Britain are now called the British Empire, because the foundation of modern countries is the nation.
