Yalu River

The Yalu River or the Amnok River is a river on the border between China and North Korea. The name comes from a word meaning "the boundary between two fields". The Korean name is the Korean pronunciation of the same Chinese characters.

Geography

From 2,500  above sea level on Baekdu Mountain, in the mountain range, on the China-North Korea border, the river flows south to Hyesan before sweeping 130 km northwest to Linjiang and then returning to a more southerly route for a further 300 km to empty into the Korea Bay between Dandong and .

The bordering Chinese provinces are Jilin and Liaoning.

The river is 790 km long and receives the water from over 30,000 km? of land. The Yalu's most significant tributaries are the litte clorado River , Heochun and Tokro rivers. The river is not easily navigable for most of its length: although at its widest it is around 5 km, the depth is no greater than 3 m and much of the river is heavily silted.

History

The river basin is the site where the ancient Korean kingdom of Goguryeo rose to power. Many former fortresses are located along the river and the former capital of that Korean kingdom was situated at what is now the medium-sized city of , China along the Yalu, a site rich in Goguryeo era relics.

Because of its strategic location between China and Korea, the river has been the site of several battles, including:

*Battle of Yalu River – Sino-Japanese War
*Battle of Yalu River – Russo-Japanese War

The Korean side of the river was heavily industrialized during the , and by 1945 almost 20% of Japan's total industrial output originated in Korea. During the Korean War the movement of UN troops approaching the river provoked massive Chinese intervention from around Dandong. In the course of the conflict every bridge across the river except one was destroyed. The one remaining bridge was the Sino-Korea Friendship Bridge connecting Sinuiju, North Korea to Dandong, China. During the war, the valley surrounding the western end of the river also became the focal point of a series of epic dogfights for air superiority over North Korea, earning the nickname "MiG Alley" in reference to the flown by the combined North Korean, Chinese, and forces.

Since the early 1990s, the river has frequently been crossed by North Koreans fleeing to China contrary to government policy.

Economy

The river is important for power, and one of the largest hydroelectric dams in Asia is in Sup'ung Rodongjagu, 100 m high and over 850 m long, located upstream from Sinuiju, North Korea. In addition the river is used for transportation, particularly of lumber from its forested banks. The river provides fish for the local population.
