Yalu River

The Yalu River (also called the Amrok in Korea, and erroneously Yalü) is a river on the border between North Korea and China. Together with the Tumen River to its east, and a small portion of Baekdu (Changbai) Mountain, the Yalu forms the border between North Korea and China and is notable as a site involved in military conflicts in the First Sino-Japanese War, the Russo-Japanese War, and the Korean War.
