Reasons for such borrowing has been reluctant "to reinvent the wheel." At a time when primitive tribes begins the transition to the state system, their high priests and leaders of the best options for their own learning throughout the state believed in the more developed at that time the neighbors. They took over the knowledge and skills in policy, administrative order, in the crafts and trade business, as well as the art of war. Along with this, and the language of neighboring developed countries to take as a state in those at the initial stage of development States. However, the impact on Korea more developed neighbors of China was not only in language and literature. State structure of the country for a long time was, albeit with small deviations from standards, a copy of the Chinese. A similar situation in the USSR in the 60's and 70's of the last century. Everything from the number of ministries and their functions to the rituals that have existed in the State of China was transferred to Korea. Moreover, the state structure of the country during the Ly Dynasty was a miniature of the structure of China which existed during the Tang and Sung dynasties.
It is surprising that Korean historians prefer to say nothing about it fact. Political relations with China in Korea were in the nature of allied. But in a period of 15 to 19 century, these relations were on a "severe service". The Korean Government has recognized the primacy of China and its emperor, and was obliged to provide assistance to its neighbor in military operations in areas located near the Korean border. In return, the Chinese government has guaranteed its support of Korea in repelling incursions into its territory from by warlike neighbors. Today, many historians have condemned a political stance Korea.
However, even if the cultural ties and a great respect for the Korean elite to Chinese culture, it is still clear that if Korea in those days would have acted against China, such a move would simply lead to the death of the country. This position of historians today is based on national interests, aimed at reducing foreign to Korea influence. The same politicians took Japan and Vietnam. Not so long ago, a common cultural heritage of all these countries is divided into national cultural formations. The same trend exists in the CIS countries. After all, no it would be correct to say that for example Ukrainian or Belarusian culture and language are not part of the culture of the Russian Empire or the Soviet Union. The same applies to Korea, which has long been part of the common cultural space of the East Asian region.
