1, 2) There is no reference to the People's Attorney General Office in the Constitution of the People's Republic of China. However, there are references to People's Procuratorates in Section VII of Chapter 3 of the Constitution as published in Constitutions of the Countries of the World (1983, 26-28).
A representative of the Embassy of the People's Republic of China in Ottawa confirms the existence of People's Attorney General Offices at the provincial and municipal levels in China (15 July 1991). However, the representative was unable to explain the mandate of the mentioned office whether at the municipal or provincial level.
Although neither refers to the city of Guangzhou nor to People's Attorney General Offices at the municipal level, the following information may be noteworthy. A Xinhua General Overseas News Service report equals Chief Procurator of the Supreme People's Procuratorate with Attorney General (7 Nov. 1990).
A United Press International report equals the Supreme People's Procuratorate with the National Attorney General's Office (30 Apr. 1990, 1).
Another United Press International report equals the Supreme People's Procuratorate with the Attorney General's Office (12 Dec. 1989, 1).
Finally, the United Press International also reports that the Procurator-General equals with the Attorney General (29 March 1989, 1).
Additional and/or corroborating information on the subject is currently unavailable to the IRBDC.
