Online safety & content laws in Hong Kong (2026)

Legal framework

Layered regime: Safeguarding National Security Ordinance 2024 (Article 23) and National Security Law 2020 (esp. Art. 43 Implementation Rules) drive content takedowns and site blocking; sectoral rules include the Control of Obscene and Indecent Articles Ordinance (Cap. 390) enforced by OFNAA and the Personal Data (Privacy) Ordinance anti-doxxing amendment (2021). No UK-OSA / EU-DSA-style comprehensive online-safety statute is in force.

Key points: internet & online safety in Hong Kong

1. 01No comprehensive online-safety law

   Hong Kong law does not impose ex ante duty-of-care, safety-by-design or systemic risk-assessment obligations on platforms; enforcement is sector-specific and largely reactive. No DSA/OSA-style bill has been introduced to LegCo as of 2026.

2. 02National-security takedown & blocking powers

   Under Article 43 of the National Security Law and its Implementation Rules (Schedule 4), police may, with the Secretary for Security's approval, require message publishers, platforms, hosts and ISPs to remove or restrict content endangering national security, with criminal penalties for non-compliance; the power has been used to block sites including HKChronicles.

3. 03Safeguarding National Security Ordinance (Article 23, 2024)

   Enacted 23 March 2024, the ordinance broadened offences (sedition, external interference, state secrets) with extraterritorial reach; several convictions have arisen from online expression, chilling platform speech and raising exposure for local staff of service providers.

4. 04Obscene/indecent content — COIAO & OFNAA

   The Control of Obscene and Indecent Articles Ordinance (Cap. 390) applies to online material; the Office for Film, Newspaper and Article Administration (OFNAA), Hong Kong Police and Customs enforce it, and a voluntary Code of Practice with HKISPA governs ISP handling of Class III (obscene) content.

5. 05Anti-doxxing regime under PDPO

   The Personal Data (Privacy) (Amendment) Ordinance 2021 criminalised doxxing and empowered the Privacy Commissioner to investigate, prosecute and issue cross-border cessation notices to platforms; the regime remains a principal statutory route for compelling online content removal outside the security context.

6. 06No age-verification/minors regime

   In a July 2026 LegCo reply, the Secretary for Innovation, Technology and Industry ruled out banning or age-gating social media for adolescents, citing enforcement difficulty and impact on the tech ecosystem; approach relies on education, health guidance and voluntary platform guidelines.
