<p>In June 1930, over 430 Altai-Urianhai families moved across the Altai Mountains to Xinjiang, China. This "escape" triggered a chain of cross-border movements going out of Mongolia, initially in the region of western Mongolia and then spreading all along the border areas close to China. Altai-Urianhai's reports presented at the national congress meetings, as well as maps they produced and submitted to the governments, show that their territory had shrunk due to Kazakh domination of the region and unfavorable governmental policies. They stated that their motherland was the Chingel River to the west of the Altai Mountains, pleading for the government to return it to them. Furthermore, the government of the People's Republic of Mongolia, which was undertaking nation-state building, had started to introduce the school-education system and the conscription system. The Altai-Urianhai people considered not only those systems but also the government to be those of "Halha's", "red", and therefore "evil". In this context, they did not "escape" from their motherland, but rather returned to their homeland. Those suffering in other areas of Mongolia took the incident to be an "escape from the motherland" or a "form of resistance" rather than a "return home". In other words, they "de-contextualized" the incident from Altai-Urianhais' historical contexts, and "re-contextualized" it into their own positions in the situation of that time. Thus developed the mass refugee movements in the early 1930s in Mongolia.</p>
