In recent years, with the development of the China-Mongolian friendly relations between the two countries, bilateral trade and economic, scientific and cultural cooperation in various areas, expanding exchanges between the two countries continues to grow. In this paper, I’ve researched situation of Mongolia’s mining sector and its importance in economy as its focus. Even though Mongolia has vast land rich in coal, copper and uranium deposits, these deposit’s prices are gradually rising, foreign direct investment plays a crucial role in development of its sector. Thus, as Mongolia’s biggest and most available market, Chinese enterprises have contributed a lot in mining sector. But in recent years, as political situation is becoming more unstable and FDI is decreasing, I have drafted some possible methods for current and prosperous Chinese enterprises using SWOT analysis to more clearly understand pros and cons of investing in Mongolian mining sector.
