Liaoning is located in the southern part of China’s Northeast. Liaoning borders the Yellow Sea (Korea Bay) and the Bohai Gulfin the south, North Korea in the southeast, Jilin Province to the northeast, Hebei Province to the west, and Inner Mongolia to the northwest.
The Yalu River marks the border between North Korea and the Chinese provinces of Jilin and Liaoning. It empties into the Korea Bay between Dandong (Liaoning) and Sinŭiju (North Korea).
The coastline of Liaoning Province is 2,178 km long - nearly 12% of China's total. The hilly regions in east Liaoning are the main area for forest. Adjoining the long, narrow costal plains (usually called the Liaoxi Corridor) is the main road for northeast China, linking with north China. Liaohe Plain in Central Liaoning, as a part of the Northeastern China Plain, has sedimentary deposits from the Liaohe River and other tributaries. The plain has abundant water and fertile soil, and is the main farming area and commodity grain base in the province.
