Revitalize The Old Northeast Industrial Bases (simplified Chinese: 振兴东北老工业基地; traditional Chinese: 振興東北老工業基地; pinyin: Zhènxīng Dōngběi Lǎo Gōngyè Jīdì), also Revitalize Northeast China or Northeast China Revitalization, is a policy adopted by the People's Republic of China to rejuvenate industrial bases in Northeast China. The areas targeted once functioned as the center of heavy industry in China, first under Japanese-occupation (Manchukuo and Kwantung Leased Territory) and then under the state-led development of the People's Republic of China before reform and opening-up. Since the 1980s, the region has been heavily affected by the restructuring of the Chinese economy and the closing and consolidation of many heavy industry State-owned enterprises (SOEs). It covers three provinces: Heilongjiang, Jilin, and Liaoning, collectively referred to as Dongbei, as well as the five eastern prefectures of Inner Mongolia: Xilin Gol, Chifeng, Tongliao, Hinggan and Hulunbuir.
