Online fraud is prosecuted under Article 266 of the Criminal Law (fraud) and the Supreme People's Court and Supreme People's Procuratorate Interpretation on telecom and online fraud cases. In the event of a cyber crime investigation involving company systems or employees, immediate legal counsel can protect corporate interests and ensure proper cooperation with authorities. Where local counterparties rely on relationship pressure, I re-anchor discussions to contract text, statutory rights, and verifiable performance records. Sun graduated from Tsinghua University Law School and completed advanced training in digital forensics at the National Judges College. " Article 286 addresses the destruction of computer systems and data. The threshold for "large amount" in online fraud is RMB 3,000, with "huge amount" at RMB 50,000 or more. Sentences range from three years to life imprisonment depending on the amount involved and the number of victims. The 2021 Interpretation on telecom and online fraud establishes that the number of defrauded persons, the total amount involved, and whether the fraud caused serious consequences such as victim suicide or mental illness are all aggravating factors for sentencing.
