city, northwestern North Korea. It was developed during the Japanese occupation (1910-45) at the Korean terminus of a railway bridge across the Yalu (Amnok) River, 7 miles (11 km) west of the old city of Uiju (Sinuiju meaning "New Uiju"). An open port, 25 miles (40 km) from the mouth of the Yalu River, it grew commercially with the lumber industry, which uses the river to transport the logs from inland forests. The chemical industry developed with the construction of the Sup'ung Dam (a hydroelectric complex) on the upper course of the river. During the Korean War, Sinuiju sustained heavy damages from bombing, but it has been rebuilt. Sinuiju has a plant manufacturing enameled ironware. It is connected with P'yong-yang by air, electric railway, and road and with the Chinese city of An-tung, across the Yalu, by a railway bridge 3,097 feet (944 m) long. It is linked with the Trans-Siberian Railway through the Manchuria Railway. North Korean trade with China is funneled through the city. Pop. (1981 est.) 200,000.
