Legal basis: Criminal Procedure Law of People's Republic of China (PRC).
Article 116 The interrogation of a criminal suspect must be conducted by investigators of a people's procuratorate or a public security organ. During interrogation, there shall be no fewer than two investigators. After the criminal suspect is sent to the detention center for custody, the investigators shall interrogate him in the detention center. Although there is no provision that lawyers have the right to be at the scene of interrogation, Chinese laws stipulate that prisoners can be recorded or videotaped, which guarantees human rights to the maximum extent.
121st investigators may record or video the interrogation process when interrogating a criminal suspect. For cases that may be sentenced to life imprisonment or death penalty or other major criminal cases, the interrogation process shall be recorded or videotaped.
Audio or video recording should run through the whole process and remain intact.
