China–Mongolia relations

China–Mongolia relations (Chinese: 中国—蒙古国关系, Mongolian: Монгол-Хятадын харилцаа) refer to the bilateral relations between Mongolia and China. These relations have long been determined by the relations between China and the Soviet Union, Mongolia's other neighbour and main ally until early 1990. With the rapprochement between the USSR and China in the late 1980s, Chinese-Mongolian relations also began to improve. Since the 1990s, China has become Mongolia's biggest trading partner, and a number of Chinese businesses operate in Mongolia.
