Permanent historical research hub. This page traces the evolution of Internet censorship and Internet-related persecution in mainland China. It separates network blocking and technical controls from law, platform governance, identity controls and individually documented persecution cases. A detention that follows Internet activity does not by itself prove which surveillance technology or investigative method identified the user.
Related archive: VIP Reference (大参考) / 小参考 Historical Archive preserves the publication family that became an important early test of cross-border electronic distribution and state attempts to suppress it.
Controlled historical timeline
1997 — Internet security and content-control regulations
The Ministry of Public Security’s Computer Information Network and Internet Security, Protection and Management Regulations were approved by the State Council on December 11, 1997 and promulgated on December 30. They placed Internet security/protection management under public-security supervision and prohibited broad categories of online content. The current official CAC publication preserves the original promulgation metadata while reflecting later revision history. Official CAC text.
1998–1999 — VIP Reference and the Lin Hai prosecution
VIP Reference, a Chinese-language electronic publication run by overseas democracy advocates, used mass email distribution and changing technical routes to send uncensored political information into mainland China. Internet entrepreneur Lin Hai was prosecuted after supplying email addresses later used by the publication and was sentenced to two years. The primary indictment, judgment and appeal ruling remain acquisition targets; the case should not be used to infer an unverified surveillance method.
In October 1999, Newsweek profiled Shengde Lian — rendered by the magazine as “Hengde Lian” — in connection with large-scale distribution of VIP Reference. Historical source record · Shengde Lian / 连胜德 profile · Media Archive.
2002 — Blocking reaches a major search engine
Contemporaneous reporting documented Google becoming inaccessible in mainland China while users relied on proxy servers to bypass blocking. Technical measurement evidence is still being acquired before this archive assigns a precise mechanism or nationwide duration.
2004–2005 — Shi Tao and account-data disclosure
The Shi Tao case demonstrated the human consequences of platform-held account and subscriber data. Court evidence, as summarized by the Committee to Protect Journalists, included Yahoo account/IP subscriber information used to identify the sender of an email. Shi Tao received a ten-year sentence in 2005. The original judgment and complete evidence chain remain acquisition targets; the disclosure should not be generalized into a claim about unrelated cases.
2009 — Green Dam Youth Escort
MIIT directed computer makers to preload Green Dam filtering software on new machines, extending proposed content control toward endpoint software. The planned universal rollout was delayed before the July 1 deadline. The original MIIT notice and final policy disposition remain primary-source acquisition targets.
2010 — Google ends censored mainland search
After publicly citing cyberattacks and restrictions on free expression, Google stopped operating its censored mainland search service and redirected search traffic to Google.com.hk. Cyberattack attribution and later accessibility are separate evidence questions from Great Firewall filtering and are tracked separately.
2015–2017 — Pressure on circumvention services
VPN providers reported significant connection failures in 2015. In 2017, MIIT launched a nationwide cleanup of unauthorized Internet access services under document 工信部信管函〔2017〕32号. Official CAC reporting confirms the policy action; the original MIIT notice remains an acquisition target. The archive does not characterize personal VPN use as uniformly criminalized.
2017 — Cybersecurity Law
The PRC Cybersecurity Law, adopted on November 7, 2016 and effective June 1, 2017, established broad network-operator, cybersecurity and data-governance duties within a national-security and cyberspace-sovereignty framework. Specific censorship or persecution outcomes are linked only when implementing rules or case evidence support them. Official 2016 CAC full text. Later amendments are tracked separately so historical wording is not silently replaced by current law.
2021 — Data governance expands
The Data Security Law and Personal Information Protection Law added major data-security and personal-information frameworks. They are included as institutional context, not treated automatically as censorship laws. Enforcement affecting online publication, identity or cross-border information must be documented separately.
2022 — Algorithm and account governance
The Internet Information Service Algorithmic Recommendation Management Provisions, effective March 1, 2022, regulate recommendation systems and include requirements concerning illegal or harmful information and online public opinion. Official CAC full text.
The Internet User Account Information Management Provisions, effective August 1, 2022, strengthened account-information and identity-management obligations. Provider duties are distinguished from any claim about state investigative access. Official CAC full text.
2024 — Revised State Secrets Law
The revised State Secrets Law took effect May 1, 2024. It forms part of the broader information-control and national-security environment, but this archive does not infer that every online-information prosecution derives from it. Official State Secrets Bureau full text.
2026 — Lu Huihuang and rapid post-release control
In September 2026, human-rights reporting said rights defender Lu Huihuang was detained again shortly after completing a four-and-a-half-year prison term. Reports said he used uncensored Internet access at a friend’s home on September 4 to seek outside help and that both men were taken away the following day. The short interval is historically significant, while the precise technical or investigative method by which authorities identified the activity remains unverified.
Evidence architecture
This hub maintains linked layers for primary laws and regulations, technical and contemporaneous media records, individually sourced persecution cases, people and organizations, and publication archives. Historical records are preserved with dated updates rather than silently rewritten when later evidence appears.

Reader Action
Preserve source links and archived copies, cite the exact case record when reporting Internet-related persecution, and distinguish confirmed facts from assumptions about surveillance technology.
