It is the largest Chinese border city, facing Sinuiju, North Korea, across the Yalu River, which demarcates the Sino-North Korean border. To the southwest of the city, the river flows into Korea Bay. Dandong has therefore had a dynamic history because of its strategic location for the northeast's rich natural resources and because of its convenient access to the ocean. It is designated as a major export production centre for the province, and is a port city connected by rail with Shenyang and Sinuiju. A significant amount of trade with North Korea flows through the city.
