Northeast China, historically known as Manchuria, became a major industrial center during China’s First Five-Year Plan (1953–57) primarily because of the extensive economic infrastructure left behind by the Japanese during their occupation of the region from 1932 to 1945.12

During the occupation, the Japanese had transformed the region into an industrial and military base, developing significant heavy industries, including iron and steel production in cities like Anshan. Following the establishment of the People’s Republic of China, the communist government prioritized the reconstruction of these existing plants to serve as a foundation for the nation's broader industrialization.13

This development was further supported by the region's proximity to Korea, its established industrial and military presence, and the availability of Soviet economic advisers and technical specialists who helped implement economic planning and management techniques. Consequently, Northeast China received the bulk of Chinese industrial investment during the First Five-Year Plan, allowing it to become a primary industrial heartland.21
