Hong Kong Security Report — September 25, 2026

Security analysis based on open-source intelligence and web research. Period: September 18 — September 25, 2026.

Executive Summary

Hong Kong's security posture during the period of September 18-25, 2026, was marked by a confluence of internal security preparations and significant external geopolitical developments. A major incident involved the unexpected diversion of advanced F-35 fighter jet components to Hong Kong, raising international concerns about potential espionage and reverse-engineering by China. Domestically, the Hong Kong government unveiled its first Five-Year Plan for Economic and Social Development (2026-2030), which explicitly aims to strengthen national security legal and enforcement mechanisms. Concurrently, the Hong Kong Police Force conducted multiple large-scale counter-terrorism and security exercises in anticipation of upcoming international events, demonstrating a heightened state of readiness against hybrid threats. Diplomatic tensions escalated as the European Parliament condemned Hong Kong's human rights situation and urged sanctions, while protests related to Hong Kong's freedoms were visible during the US-China summit in Washington D.C.

Key Security Developments

• F-35 Component Diversion Incident
  On September 18, a shipment of F-35 components, containing advanced stealth technology, was unexpectedly diverted to Hong Kong while in transit from Australia to the United States. This incident has prompted an investigation by a U.S. House committee overseeing defense policy, raising significant concerns that the People's Republic of China (PRC) may have gained access to these components for potential reverse-engineering purposes. The diversion highlights ongoing espionage and hacking operations by the PRC aimed at acquiring advanced U.S. fighter aircraft technology.

• Hong Kong's First Five-Year Plan for Economic and Social Development (2026-2030)
  Unveiled on September 16 by Chief Executive John Lee, this inaugural Five-Year Plan for Hong Kong sets out a strategic vision for the city's development, with a strong emphasis on national security. The plan explicitly states that Hong Kong will strengthen its top-level structure and enhance the legal system and enforcement mechanism for safeguarding national security under the holistic national security approach. This aligns Hong Kong's development with China's 15th Five-Year Plan and aims to ensure stability and prosperity.

• Large-Scale Counter-Terrorism and Security Exercises
  The Hong Kong Police Force (HKPF) conducted several significant security exercises during this period. On September 22, a major emergency drill was held at AsiaWorld-Expo, involving over 300 personnel, simulating a terrorist attack to test evacuation, rescue, and inter-agency coordination. Additionally, on September 23, the HKPF, in collaboration with various government departments, conducted a comprehensive inter-departmental exercise at the Hong Kong Convention and Exhibition Centre, Victoria Harbour, and the West Kowloon area, in preparation for the 94th INTERPOL General Assembly in November. These drills, alongside the "Counter Cyber & Physical Terrorism Joint Exercise 2026" (codenamed "STEALTHNET") conducted on April 16 (reported in May), tested responses to hybrid terrorist threats, including cyber and physical attacks against critical infrastructure, and involved international cooperation.

• EU Parliament Condemns Human Rights Situation and Urges Sanctions
  On September 17, the European Parliament adopted a resolution strongly condemning the deteriorating situation of media freedom and freedom of expression in Hong Kong, following recent arrests and sentencings under the National Security Law and the National Security Safeguarding Ordinance. The resolution called for the Council to urgently impose sanctions on Hong Kong authorities and officials responsible for the repression of freedoms, specifically mentioning Chief Executive John Lee. This move was met with strong dissatisfaction and firm opposition from the Commissioner's Office of the Chinese Foreign Ministry in the HKSAR and the HKSAR government, who criticized the EU for misrepresenting national security laws and interfering in China's internal affairs.

• Protests During US-China Summit in Washington D.C.
  During the US President Donald Trump and Chinese President Xi Jinping summit in Washington D.C. on September 24, protesters gathered outside the White House, chanting "Free Hong Kong" and calling for the release of political prisoners, including media tycoon Jimmy Lai. This public demonstration underscored persistent international concerns regarding human rights and political freedoms in Hong Kong, bringing these issues to the forefront of high-level diplomatic engagements.

• China's Military Leadership Purge
  News emerged on September 25 that China's ruling Communist Party had expelled two senior generals, Zhang Youxia and Liu Zhenli, from the party and the military this week. While not directly related to Hong Kong's internal security, this purge within the People's Liberation Army (PLA) raises questions about its war-waging ability and is seen as strengthening President Xi Jinping's control over the military. This development has regional implications for stability, particularly concerning Taiwan and disputed areas in the South and East China Seas.

• Hong Kong's Economic Security and International Engagement
  Hong Kong continued to actively engage in international economic diplomacy. On September 20, Hong Kong signed the First Protocol to Amend the Investment Agreement with ASEAN, aiming to enhance economic, trade, and investment relations. The city also hosted the 11th Belt and Road Summit (September 9-10, reported during this period), attracting over 6,200 global leaders to explore business opportunities and strengthen Hong Kong's role as a "super connector". These initiatives are part of Hong Kong's strategy to secure its long-term economic development and international competitiveness.

Geopolitical Impact and Regional Dynamics

Hong Kong's security developments during this period significantly underscore its complex position within broader geopolitical dynamics, particularly concerning US-China and EU-China relations. The F-35 component diversion incident directly implicates Hong Kong in a high-stakes security concern between the United States and China, potentially fueling further distrust and technological competition. This event, occurring in Hong Kong, highlights the city's vulnerability as a transit hub and a potential target for intelligence operations, thereby intensifying the strategic rivalry between major powers.

The European Parliament's resolution condemning human rights in Hong Kong and urging sanctions against officials reflects a persistent Western critique of Beijing's tightening control over the city. This diplomatic pressure from the EU, although rejected by China and the HKSAR government, contributes to the narrative of an eroding "One Country, Two Systems" framework and could lead to further punitive measures or strained diplomatic ties between the EU and China. The protests outside the White House during the US-China summit further amplified these concerns on the global stage, demonstrating that Hong Kong remains a significant flashpoint in US-China relations, despite efforts by both leaders to foster a "constructive strategic stability".

Regionally, Hong Kong's First Five-Year Plan, with its explicit alignment with national security objectives, signals a deeper integration into mainland China's strategic framework. This move, while aimed at ensuring stability and prosperity for Hong Kong, could be perceived by some international actors as a further curtailment of the city's autonomy, potentially affecting its unique international standing and its role as a global financial and trade center. The ongoing purges within the Chinese military leadership, while not directly in Hong Kong, contribute to a broader regional dynamic of increased Chinese military assertiveness and internal consolidation of power under President Xi Jinping, which indirectly impacts Hong Kong's security environment by shaping China's overall strategic posture in the Indo-Pacific.

Military and Defense Analysis

Hong Kong, as a Special Administrative Region of China, does not maintain its own independent military force; its defense falls under the purview of the People's Liberation Army (PLA) Hong Kong Garrison. During this reporting period, there were no direct reports of significant PLA Hong Kong Garrison activities or defense spending trends specific to Hong Kong. However, the broader context of China's military modernization and internal purges is highly relevant.

The purges of senior military commanders within the People's Liberation Army, including Generals Zhang Youxia and Liu Zhenli, reported on September 25, indicate a continued effort by President Xi Jinping to tighten his control over the armed forces. While these purges raise questions about the PLA's immediate war-fighting readiness, particularly concerning complex operations like a potential conflict over Taiwan, they are ultimately seen as strengthening Xi's dominance over the party-state and the military. This consolidation of power suggests a continued trajectory of military modernization and increased assertiveness in areas like the South China Sea and around Taiwan, which indirectly shapes the strategic environment around Hong Kong.

In terms of defense capabilities relevant to Hong Kong's internal security, the Hong Kong Police Force demonstrated enhanced capabilities through various counter-terrorism exercises. The "STEALTHNET" exercise earlier in the year, and the drills conducted on September 22 and 23, focused on hybrid threats, including cyber and physical attacks, and involved cross-border intelligence sharing and coordinated responses. The emphasis on developing an "AI City Brain" integrated city management system and strengthening disaster prevention and response capabilities, as outlined in the Five-Year Plan, indicates a strategic shift towards leveraging advanced technology for comprehensive security and resilience. This suggests a modernization program for internal security forces, focusing on intelligence analysis, rapid reaction, and inter-agency cooperation, particularly in urban and critical infrastructure environments.

Outlook and Forecast

Short-term trends (1-3 months): In the immediate future, Hong Kong is likely to experience a heightened security presence, particularly around the Hong Kong Convention and Exhibition Centre in Wan Chai, leading up to and during the APEC Finance Ministers' Meeting (October 20-21) and the 94th INTERPOL General Assembly in November. The recent counter-terrorism drills indicate a proactive stance against potential threats, including cyber and physical attacks. Diplomatic tensions with Western powers, particularly the EU, are expected to persist following the European Parliament's resolution and the HKSAR government's strong rejection. The implications of the F-35 component diversion will likely continue to unfold, potentially leading to further investigations and diplomatic exchanges between the US and China.

Critical flashpoints and risk areas: The primary flashpoints for Hong Kong's security remain the ongoing enforcement of the National Security Law and the Safeguarding National Security Ordinance, which continue to draw international criticism and fuel concerns over civil liberties. Any further arrests or convictions of pro-democracy activists or media figures could exacerbate diplomatic tensions and potentially trigger renewed protests, albeit under strict security measures. The Hong Kong Port and other critical infrastructure remain potential targets for espionage or security breaches, as highlighted by the F-35 component incident. The broader geopolitical rivalry between the US and China, particularly concerning technology and regional influence, will continue to cast a shadow over Hong Kong's security and economic stability.

Indicators to monitor: Key indicators to monitor include the rhetoric and actions of the HKSAR government regarding national security enforcement, particularly in response to international criticism. The nature and scale of any future protests or demonstrations will be important, as will the government's response. Developments in US-China and EU-China relations, especially regarding trade, technology, and human rights, will directly impact Hong Kong's external environment. The progress of investigations into the F-35 component diversion and any subsequent measures taken by the US or China will also be crucial. Furthermore, the implementation details of Hong Kong's First Five-Year Plan, particularly those related to strengthening national security mechanisms and developing an "AI City Brain," should be closely watched for their practical implications on governance and civil society.

Strategic recommendations: Hong Kong should prioritize strengthening its cybersecurity defenses and intelligence capabilities to mitigate risks from espionage and hybrid threats, as demonstrated by the recent counter-terrorism exercises and the F-35 incident. Diplomatically, the HKSAR government could seek to engage in more transparent dialogue with international bodies to address human rights concerns, while firmly upholding its "One Country, Two Systems" framework. From an economic security perspective, diversifying international partnerships beyond traditional alliances, as seen with the ASEAN investment agreement and Belt and Road Initiative engagements, can help bolster resilience against geopolitical pressures. Internally, fostering social cohesion and addressing underlying societal concerns, while maintaining a firm stance on national security, will be crucial for long-term stability.
