Hong Kong Security Report — September 17, 2026

Security analysis based on open-source intelligence and web research. Period: September 10 — September 17, 2026.

Executive Summary

During the period of September 10 to September 17, 2026, Hong Kong's security landscape was primarily shaped by the continued rigorous enforcement of national security legislation and a strategic pivot towards strengthening its economic ties within a multipolar global order. A significant development was the sentencing of former leaders of the "Hong Kong Alliance" under the National Security Law, reaffirming the government's commitment to national security. Concurrently, the Hong Kong Chief Executive's Policy Address on September 16, 2026, highlighted the completion of local legislation for Article 23 of the Basic Law, emphasizing a "holistic approach to development and security." Cybersecurity remained a critical concern, with the Hong Kong Computer Emergency Response Team Coordination Centre (HKCERT) releasing its 2026 outlook, warning of record-high incidents driven by AI-related attacks and supply chain vulnerabilities. Diplomatically, Hong Kong hosted the Belt and Road Summit, signaling its intent to become a key financial hub for Eurasian and Global South economies amidst shifting geopolitical dynamics.

Key Security Developments

• National Security Law Enforcement and Sentencing
  On September 11, 2026, a Hong Kong court sentenced three former leaders of the now-disbanded "Hong Kong Alliance in Support of Patriotic Democratic Movements of China" to prison terms ranging from five years and two months to seven years and three months under the national security law. Former chairman Lee Cheuk-yan received seven years, former vice-chairwoman Chow Hang-tung received seven years and three months, and former vice-chairman Albert Ho Chun-yan received five years and two months. The group was also fined HK$1.5 million (approximately $192,000) for inciting subversion over their long-standing call to end "one-party dictatorship" in mainland China. This sentencing underscores the Hong Kong government's unwavering stance on national security and its determination to prosecute acts deemed to endanger state power.

• Completion of Article 23 Legislation and Policy Address
  The Chief Executive's 2026 Policy Address, delivered on September 16, 2026, proudly announced the completion of local legislation for Article 23 of the Basic Law, fulfilling a constitutional responsibility that took over 26 years. This new "Safeguarding National Security Ordinance" is intended to establish a comprehensive and effective shield for national security, aiming to maintain the city's prosperity and stability and create a more predictable environment for business and development. The Policy Address emphasized a "holistic approach to development and security," indicating that security considerations will underpin all governance agendas.

• Heightened Cybersecurity Threats and Government Response
  The Hong Kong Computer Emergency Response Team Coordination Centre (HKCERT) released its "Hong Kong Cybersecurity Outlook 2026," revealing a record high of 15,877 cybersecurity incidents in 2025, a 27% year-on-year increase. The report identified AI-related attacks, weak AI governance, third-party exposure, over-reliance on cloud infrastructure, and emerging threats from AI-enabled devices as top concerns for 2026. In response, the Chief Executive's Policy Address announced a "Cybersecurity Defence Programme" to provide certification for local organizations and develop shared defense tools. Furthermore, a "Cybersecurity Threat Intelligence Analysis and Alert System" will be developed, utilizing AI to collect international cyber-threat intelligence and issue risk alerts to critical infrastructure operators.

• Diplomatic and Economic Re-alignment via Belt and Road Summit
  Hong Kong hosted the 11th Belt and Road Summit on September 10, 2026, which served as a platform to accelerate its realignment in global commerce. The summit highlighted Hong Kong's transition into a strategic clearinghouse for an emerging multipolar order, particularly for non-aligned Eurasian and Global South economies. A significant outcome was a memorandum of understanding signed between Hong Kong and the Central Bank of Uzbekistan to deepen bilateral gold market cooperation, positioning Hong Kong as an international bullion trading, clearing, and vaulting hub. ASEAN Secretary-General Kao Kim Hourn also reaffirmed support for Hong Kong's accession to the Regional Comprehensive Economic Partnership (RCEP).

• Military Firing Practices
  Routine military firing practices were scheduled to take place at two military sites in Hong Kong during September 2026: the San Wai/Tai Ling Firing Range and the Tsing Shan Firing Range. Red flags or lamps are hoisted at these areas during practice, and the public is advised not to enter for safety reasons. These exercises are part of the People's Liberation Army (PLA) Hong Kong Garrison's regular training schedule.

• Counter-Terrorism Preparedness and Intelligence
  The Hong Kong Police Force (HKPF) continues to prioritize strengthening its intelligence gathering and counter-terrorism capabilities as part of its 2026 operational priorities. This includes deterring and preventing terrorist activities through inter-departmental cooperation and enhancing public awareness of terrorism, including domestic terrorism and self-radicalization. While no specific counter-terrorism incidents were reported during this week, a large-scale inter-departmental counter-terrorism, major incident, and protective security exercise was conducted in June 2026 at Hong Kong International Airport and Tung Chung, in preparation for major international conferences later in the year.

• Cybersecurity Collaboration in Greater Bay Area
  A Hong Kong cybersecurity industry delegation attended the 2026 China Cybersecurity Week events in Jinan and Guangzhou, with the Assistant Commissioner (Project Governance and Cybersecurity), Mr. Ken Siu, slated to attend the Macao Sub-forum on September 18. This participation aims to deepen ties among Guangdong, Hong Kong, and Macao in cybersecurity and consolidate the Greater Bay Area cybersecurity collaboration network. The delegation's presence highlights Hong Kong's commitment to regional cooperation in addressing evolving cyber threats, particularly those amplified by AI.

Geopolitical Impact and Regional Dynamics

Hong Kong's security developments during this period reflect its ongoing integration with mainland China's governance framework and a strategic reorientation in its international economic engagement. The stringent enforcement of the National Security Law, culminating in the sentencing of prominent pro-democracy figures, reinforces Beijing's tightening control over the city's political and legal landscape. This approach, while lauded by the HKSAR government as essential for stability and prosperity, continues to draw strong condemnation from Western countries, who view it as an erosion of Hong Kong's autonomy and human rights. The HKSAR government, however, firmly rejects these criticisms as politically motivated interference in its internal affairs.

Economically, Hong Kong is actively repositioning itself within a shifting global order. The Belt and Road Summit on September 10, 2026, underscored Hong Kong's ambition to serve as a crucial financial and trade conduit for an "emerging multipolar order," particularly focusing on Eurasian and Global South economies. This pivot is a direct response to "Western sanctions, trade barriers, and maritime chokepoints" that are disrupting traditional supply corridors, indicating a strategic move to insulate itself from Western-centric financial architectures. The support from ASEAN for Hong Kong's accession to RCEP further solidifies its regional economic integration and alignment with China's broader geopolitical and economic initiatives.

The emphasis on "security brings prosperity" in the Chief Executive's Policy Address on September 16, 2026, signals a clear message that political stability, as defined by Beijing, is the prerequisite for economic development. This narrative aims to attract global capital by presenting Hong Kong as a "secure port" in a volatile world, despite concerns from some international businesses about the implications of expanded national security laws on data and personal freedoms. The focus on developing the Northern Metropolis and strengthening ties with mainland Chinese metropolises further illustrates Hong Kong's deepening integration into the Greater Bay Area, with long-term implications for its distinct identity and autonomy under "One Country, Two Systems."

Military and Defense Analysis

Hong Kong's military and defense posture is primarily defined by the presence and activities of the People's Liberation Army (PLA) Hong Kong Garrison. While no new deployments or significant military incidents were reported during this specific week, routine firing practices were scheduled for September 2026 at the San Wai/Tai Ling Firing Range and the Tsing Shan Firing Range. These exercises are standard for the garrison and serve to maintain operational readiness. The PLA's presence in Hong Kong is a key component of national security, as outlined in the Garrison Law, which allows for intervention in public order at the request of the city government, though Hong Kong authorities have historically stated they can manage such situations themselves.

The Hong Kong Police Force (HKPF) plays a central role in the city's internal security and defense against non-military threats. Their 2026 operational priorities highlight a strong focus on strengthening intelligence gathering and counter-terrorism capabilities. This includes a "Three-tier Prevention Framework" and collaboration with various government departments and agencies to deter and prevent terrorist activities. The HKPF also aims to enhance public awareness of terrorism, including domestic terrorism and self-radicalization, and to protect critical infrastructure. Recent large-scale inter-departmental counter-terrorism exercises, such as "WATCHER" in July 2026 and "STEALTHNET" in April 2026, involving international cooperation with Interpol and other regional police forces, demonstrate an ongoing commitment to enhancing readiness against both physical and cyber-terrorism threats. The Chief Executive's Policy Address also mentioned the expansion of drone application by the HKPF in emergency response and crime prevention, complemented by AI technology for enhanced on-site assessment and control.

Defense spending trends for Hong Kong are not publicly detailed separately from China's overall defense budget, given that the PLA garrison is a mainland force. However, the HKSAR government's focus on enhancing cybersecurity infrastructure and counter-terrorism capabilities indicates continued investment in these areas. The "Cybersecurity Defence Programme" and the "Cybersecurity Threat Intelligence Analysis and Alert System" represent significant capability developments, particularly with the integration of AI technology to analyze threats targeting local critical infrastructure.

Outlook and Forecast

Short-term trends (1-3 months): In the immediate future, Hong Kong will likely continue to see the robust enforcement of its national security legislation, including the recently completed Article 23. The government's emphasis on "security brings prosperity" suggests that maintaining political stability and control will remain paramount, with further judicial proceedings against individuals or groups deemed to threaten national security. Economically, Hong Kong will intensify its efforts to solidify its role as a hub for Belt and Road Initiative projects and expand engagement with Eurasian and Global South economies, potentially leading to new trade and investment agreements. Cybersecurity will remain a high-priority area, with the government rolling out its new "Cybersecurity Defence Programme" and "Threat Intelligence Analysis and Alert System" to counter AI-driven attacks and supply chain risks.

Critical flashpoints and risk areas: A primary flashpoint remains the potential for renewed international criticism and targeted sanctions from Western nations in response to national security law enforcement, particularly concerning human rights and judicial independence. While the US ended its Hong Kong-related national emergency in July 2026, the underlying tensions persist. Any perceived escalation in political suppression could trigger further diplomatic friction. Internally, while large-scale protests are unlikely under the current security regime, isolated acts of defiance or online activism could still lead to arrests and further tightening of digital surveillance. The increasing sophistication of cyber threats, particularly AI-driven attacks, poses a significant risk to Hong Kong's critical infrastructure and financial sector, despite enhanced government efforts.

Indicators to monitor: Key indicators to monitor include the frequency and nature of national security arrests and prosecutions, particularly those involving foreign nationals or businesses, which could signal a broader application of the laws. Observe the implementation and effectiveness of the new cybersecurity initiatives, including the adoption rates of the certification program and the impact of the AI-driven threat intelligence system. Track Hong Kong's progress in securing new economic partnerships and investment from Belt and Road and RCEP countries, as well as any shifts in trade volumes and financial flows. Also, monitor statements from major international bodies and foreign governments regarding Hong Kong's autonomy and rule of law.

Strategic recommendations: For businesses and international organizations operating in Hong Kong, it is crucial to conduct thorough risk assessments regarding data security, legal compliance under the expanded national security laws (including Article 23, which criminalizes refusal to provide decryption assistance), and potential impacts on employee privacy. Strengthening internal cybersecurity defenses and adopting robust AI governance frameworks are essential. Diplomatically, Hong Kong should continue to articulate its "One Country, Two Systems" framework and its unique advantages as an international financial center, while actively engaging with diverse global partners to mitigate the impact of geopolitical polarization. The government should also ensure transparency and clear communication regarding the implementation of national security laws to address international concerns and maintain confidence.
