The Yalu River, known in Korea as the Amnok River, forms a major part of the international border between North Korea and China. Originating from the slopes of Mount Paektu at an elevation of 2,500 meters, it flows roughly 790 kilometers into the Korea Bay of the Yellow Sea. The river has been a site of strategic military significance throughout history, most notably during the Russo-Japanese War and the Korean War, when its bridges were targets of intense aerial bombardment. It is a critical source of hydroelectric power, with the Sup'ung Dam, constructed in 1941, being one of the largest in Asia at the time of its completion. The river also facilitates cross-border trade, primarily through the cities of Sinuiju in North Korea and Dandong in China, which are connected by the Sino-Korean Friendship Bridge. Despite political tensions, the Yalu remains an essential economic corridor, providing water for agriculture and supporting various local industries. The surrounding landscape varies from rugged mountainous terrain in the upper reaches to fertile alluvial plains near the river's mouth.
