It is also undertakes the important task of implementing strategies for production and for territorial border control. Such implementation influences both regional and national economic substantiality and social stability. This article attempts to analyze the relationship between production and border control while exploring the possible solutions for existing problems within the region, based on a historical perspective. There are three chapters in this article. The first chapter introduces the history of agricultural development and border trooping, based on the practical experiences of Han, Tang, and Qing Dynasty. The second chapter analyzes the dichotomy of agricultural production and border trooping. Border trooping needs daily rationing from agricultural production. Meanwhile, agricultural production is conditioned by border trooping. Border control is the goal ensured by agricultural productivity. However, the status of each element differs in different eras. They are the two inseparable elements. In the third chapter, the author discourses the means of adjusting border control and production according to the latest domestic and international situations. Since the socialist economic system is perfecting itself, Chinese mentality is experiencing significant changes. At the same time, the international situation changes tremendously which makes the strategic status of the region become more and more important. The production and border control mission is facing new challenges because of ethnic separatists, terrorists, and religious extremists. The article is going to provide some constructive suggestions, based on the mentioned factors.
