China and Mongolia share a borderline of 4676 kilometers long. The two countries established diplomatic relations on Oct. 16, 1949. Despite some twists and turns in their relations over the past 50 years since the establishment of their diplomatic relations, neighborliness and friendship have always remained the mainstream of Sino-Mongolian relations. Over the recent years, mutually beneficial cooperation has been developing between the two countries, and China is now Mongolia's largest trading partner and investor. Both sides share identical or similar views on many issues in international affairs, support each other and enjoy fruitful cooperation.
As China's important neighbor to its north, and situated between China and Russia, Mongolia enjoys a unique geographic position. For years, the Chinese Government has consistently pursued a neighborly and friendly policy toward Mongolia. It respects independence and sovereignty of Mongolia, the development course chosen the Mongolian people themselves and nuclear-free status upheld by Mongolia.
