It had been formed largely on the initiative of Imperial Japanese Army commanders in north China, before securing approval from Japanese government authorities in Tokyo. Thus the Provisional Government had nominal authority in Japanese occupied zones in north China, while to the south the Central China Expeditionary Army established the Reformed Government of the Republic of China in 1938, which had authority in the Yangtze River area. Both essentially served as a local organ of the Japanese military authorities, due to the presence and extensive powers of Japanese advisors within the Provisional Government over native Chinese bureaucrats, and because it never made any attempt to secure international recognition, even from Japan.
