The rich historical relationship between Mongolia and the Central Asia countries have lasted for over that 3,000 years. During this period there have been times of peace and times when the peace was broken. The conquering and domination of Central Asia during the 2nd century BC has been documented in historic documents. Modun Shanyu moved west, into present-day Kazakhstan, conquering the nomadic Wusun and also 26 cities in Southern and Northern Turkestan, uniting them with the Xiongnu. The following has been noted in the sources: “From the north the Xiongnu collected levy from nearby Kangju and Ferghana (Dayuan), and communicated with the Qiang in the south,” “The Western countries are coming under the domination of the Xiongnu.” “The This work was supported by Hankuk University of Foreign Studies Research Fund of 2011 Xiongnu have conquered many countries and have become powerful.” In the year 174 B.C. in a letter to Han China, Modun Shanyu wrote: “Punishing the western xian wang, we send the Yuezhi against the west. With the blessing of heaven, I have the opportunity to destroy the Yuezhi as my commanders and soldiers are in good shape as well as their horses. I have suppressed the Loufan, Wusun, Hujie and their 26 countries, all of them surrendering to Xiongnu. Thus all archer people have become one big family.” We can name precious archeological findings that have been found in Mongolia related with the rich history and artifacts from the Xiongnu period. This is not only connected with the Silk Road- the bridge between the north and the south which the Xiongnu were keeping under the control but also the historical fact that the political, economic and cultural relations have been established between the countries. As this relation has lasted for many years, later in the mid 6th century Turkic countries originating from Central Asia have become powerful, centralized in Mongolian land establishing their country leaving their culture. They have lived in the Mongolian lands for over 360 years near Orkhon river basin and Khangai massif. In the 12 th century Chinggis Khan has established the Great Mongol Empire in the Mongolian lands uniting all Mongols, and wishing to establish peace with adjoining countries. The ancient trade road connecting the South and the North became part of the country. This indicates that Chinggis and the Mongolian aristocrats were interested in the Far East. This is also proof that this was one way to develop foreign trade and spread the news of the newly established country. At the beginning of the 17th century under Mongolia’s right wing, К вопросам возникновения и происхождения культурных союзов … 205 the powerful Four Oirat countries were established. The political foreign and domestic policy was to strengthen the new country. There were political and economic relationships among the Central Asia countries. During the late 19th century and early 20th century the relationship between Mongolia and Central Asia was inactive due to Manchurian domination, which closed off foreign relations. Since becoming a member of the UN at the beginning of the 20th century the diplomatic relations of Mongolian People’s Republic with the western countries started to prosper. During the late 1980s and early 1990s the socialist system collapsed, easily opening opportunities for Mongolia. Since then Mongolia has become an independent subject not just with open and effective foreign policy but has also become to cooperate in political, economic, cultural and other areas. In modern times in order to execute foreign policy Mongolia is confirming previous relations with new conditions and being flexible. This situation unites each and every Eurasian country with their common cultural heritage and culture, securing their own land, following world development connecting with political, economical and society culture. This is the accurate way of existing under world approval judicial and general principles.
