Liaobei or Liaopei (both: lēou´bā´), former province (c.47,000 sq mi/121,700 sq km), NE China. The capital was Liaoyuan. It was one of nine provinces created in Manchuria in 1945 by the Chinese Nationalist government. However, since the Nationalists never gained effective control of Manchuria after World War II, the province existed only on paper. It was later divided between the Inner Mongolian Autonomous Region and the provinces of Heilongjiang, Jilin, and Liaoning.
