Macau Security Report — April 23, 2026

Security analysis based on open-source intelligence and web research. Period: April 16 — April 23, 2026.

Executive Summary

During the period of April 16-23, 2026, Macau's security landscape was primarily shaped by ongoing efforts to strengthen national security, enhance regional counter-terrorism capabilities, and manage border integrity. The Macau government continued to emphasize the integration of national security requirements into its development strategy, following the recent implementation of a new national security law allowing closed-door trials. Significant regional cooperation was demonstrated through a joint counter-terrorism exercise involving Macau, Hong Kong, Singapore, and Korea, which simulated responses to cyber and physical attacks. Concurrently, Macau authorities tightened border controls, denying entry to over 2,500 mainland Chinese individuals suspected of transit scheme abuse. Diplomatic engagements by Chief Executive Sam Hou Fai in Portugal and Spain aimed to bolster Macau's role as a platform for China's international cooperation, while broader geopolitical tensions, particularly in the Middle East, were noted for their indirect economic impact on the region.

Key Security Developments

• National Security Education and Legal Framework Reinforcement
  On April 15, 2026, Macau launched its National Security Education series, with Chief Executive Sam Hou Fai stressing the importance of integrating national security into all facets of Macau's development strategy. This initiative follows the recent passing of a new national security law in March 2026, which permits closed-door trials in national security cases and mandates clearance for defense lawyers, further solidifying the legal framework for national security in the Special Administrative Region. The government aims to continuously improve Macau's legal systems and enforcement mechanisms to safeguard national security.

• Regional Counter-terrorism Exercise "STEALTHNET"
  The Hong Kong Police Force, in collaboration with Interpol and police forces from Macau (Macao Judiciary Police), Singapore, and Korea, successfully concluded the Counter Cyber and Physical Terrorism Joint Exercise 2026, codenamed "STEALTHNET," on April 16, 2026. This exercise simulated complex scenarios involving terrorist financing, cross-border cyberattacks, and physical assaults against critical infrastructure, including financial, aviation, and healthcare systems, across the participating regions. The exercise aimed to enhance intelligence sharing, coordinated rapid response, and joint operations capabilities against hybrid terrorist threats.

• Tightened Border Security and Immigration Enforcement
  Between January and April 20, 2026, Macau authorities denied entry to more than 2,500 mainland Chinese passport holders due to suspected abuse of the city's transit entry arrangement. The Public Security Police Force reported that individuals were refused entry for failing to present valid onward travel documents, not proceeding to a third country as required, or frequently entering and exiting to circumvent stay regulations. In response, Macau has tightened enforcement, including reducing permitted stay durations for repeat offenders and denying entry after multiple violations, in close coordination with mainland authorities.

• Diplomatic Engagements with Portugal
  Macau Chief Executive Sam Hou Fai concluded a working visit to Portugal on April 21, 2026, where he met with Portuguese President Antonio Jose Seguro, Speaker of Parliament Jose Pedro Aguiar-Branco, Prime Minister Luis Montenegro, and President of the Supreme Court of Justice Joao Cura Mariano. During these meetings, Sam Hou Fai emphasized Macau's commitment to elevating cooperation across various fields and leveraging its unique role as a platform for China-Portuguese-speaking countries' economic and trade relations. Eighteen cooperation agreements were signed, covering areas such as trade, sci-tech, tourism, education, and culture.

• Diplomatic Engagements with Spain
  Following his visit to Portugal, Chief Executive Sam Hou Fai met with Spain's Minister for Foreign Affairs, European Union and Cooperation, José Manuel Albares Bueno, in Madrid on April 22, 2026. The meeting aimed to enhance future exchanges and cooperation between Macau and Spain in areas including trade, investment, culture, and sci-tech innovation. Sam Hou Fai expressed Macau's desire to extend its role as a China-Portuguese-speaking countries' platform into the Spanish-speaking world, seeking Spain's support in this endeavor.

• Cybersecurity Threat Landscape Discussion
  While no specific Macau-centric cybersecurity incidents were reported during this week, the broader context of cybersecurity was highlighted by the "STEALTHNET" exercise, which included simulations of cross-border cyberattacks. Additionally, KPMG published "Cybersecurity considerations 2026" on April 16, 2026, discussing the evolving threat landscape shaped by AI, geopolitics, regulatory pressure, and supply-chain disruption, which are pertinent considerations for Macau's digital infrastructure.

• Impact of Geopolitical Tensions on Local Economy
  Geopolitical tensions in the Middle East have led to a sharp rise in international oil prices, which is directly impacting Macau's hospitality sector by increasing operating costs for hotels, particularly affecting boilers and transportation. This development, reported on April 23, 2026, highlights how global events can have tangible economic security implications for Macau, even if indirectly.

• Macau's Role in China's 15th Five-Year Plan
  Macau's Chief Executive Sam Hou Fai reiterated the government's commitment to aligning Macau's 3rd Five-Year Plan with China's 15th Five-Year Plan (2026-2030), emphasizing high-quality internal reform, high-level opening-up, and leveraging Macau's role as a "precise connector" between China and Portuguese-speaking countries. This strategic alignment underscores Macau's importance in China's broader economic and diplomatic objectives, with a focus on economic diversification and international engagement.

Geopolitical Impact and Regional Dynamics

Macau's recent security and diplomatic developments underscore its unique position as a Special Administrative Region within China, serving as a bridge for international engagement while firmly adhering to Beijing's national security directives. The emphasis on integrating national security into all aspects of Macau's development, as articulated by Chief Executive Sam Hou Fai, reflects China's overarching strategy to ensure stability and control across its territories. This approach, reinforced by the new national security law allowing closed-door trials, signals a continued tightening of internal security measures in line with mainland policies.

The participation of the Macao Judiciary Police in the regional Counter Cyber and Physical Terrorism Joint Exercise 2026, "STEALTHNET," highlights Macau's active role in regional security cooperation, particularly within the Greater Bay Area and with key Asian partners like Hong Kong, Singapore, and Korea. This collaboration demonstrates a shared commitment to addressing transnational threats such as cyberattacks and terrorism, which are increasingly complex and require coordinated responses. For major powers like the US and EU, this regional cooperation could be viewed through the lens of China's expanding influence and its efforts to secure its economic and strategic interests in the Indo-Pacific.

Macau's diplomatic outreach to Portugal and Spain by Chief Executive Sam Hou Fai is a significant aspect of its geopolitical strategy. By positioning Macau as a platform for cooperation between China and Portuguese-speaking and Spanish-speaking countries, the SAR is actively fulfilling Beijing's mandate to expand its international engagement. This strategy not only diversifies Macau's economic base beyond gaming but also strengthens China's soft power and economic ties with European and Latin American nations, potentially influencing broader EU-China relations. The focus on trade, culture, and technology cooperation aims to enhance Macau's global standing and its utility as a "precise connector" in China's foreign policy.

While direct military activities in Macau are minimal due to its SAR status, the broader geopolitical landscape, including tensions in the Middle East, has indirect economic impacts, such as rising oil prices affecting the local hospitality industry. This illustrates Macau's susceptibility to global economic shocks, even as its primary security concerns remain internal stability and regional cooperation under the "One Country, Two Systems" framework. The ongoing efforts to enhance border security and manage immigration flows also reflect a pragmatic approach to maintaining social order and preventing illicit activities, which are critical for Macau's economic stability and its image as a global tourism and leisure center.

Military and Defense Analysis

Macau, as a Special Administrative Region of China, does not maintain its own independent military forces. Its defense is the responsibility of the People's Liberation Army (PLA) garrison stationed in Macau. While there were no specific reports of PLA military activities or exercises within Macau during the reporting period, the broader context of China's military modernization and defense policy is highly relevant. The PLA garrison's presence serves as a symbol of Chinese sovereignty and a deterrent against any perceived threats to national security within the SAR. Chief Executive Sam Hou Fai has previously acknowledged the PLA garrison's role in winning the trust and respect of Macau compatriots, emphasizing the SAR's need to remain mindful of potential dangers and uphold national security.

The national security framework, which Macau is actively strengthening, underpins the defense posture by addressing internal stability, which is a core component of China's holistic approach to national security. The new national security law, allowing for closed-door trials and requiring clearance for defense lawyers in security cases, further integrates Macau into China's broader national security apparatus. This legal reinforcement, coupled with ongoing national security education, aims to prevent external interference and crack down on elements deemed destabilizing.

While Macau does not engage in defense acquisitions or have its own defense spending trends, its participation in regional security exercises, such as the "STEALTHNET" counter-terrorism drill, demonstrates a commitment to enhancing capabilities in areas like intelligence sharing and coordinated response to hybrid threats. The Macao Judiciary Police's involvement in such exercises, alongside forces from Hong Kong, Singapore, and Korea, indicates a focus on law enforcement and internal security capabilities that align with regional counter-terrorism efforts. This collaborative approach, particularly in cybersecurity and physical threat response, contributes to the overall security resilience of the Greater Bay Area.

Outlook and Forecast

Short-term trends (1-3 months): In the immediate future, Macau is likely to continue its strong emphasis on national security, particularly as it aligns its 3rd Five-Year Plan with China's 15th Five-Year Plan. We can expect further public awareness campaigns and the continued implementation of the new national security law, potentially including initial cases or legal interpretations that clarify its scope. Border security will remain a critical focus, especially with the upcoming May Day holiday, as authorities maintain heightened vigilance against transit scheme abuse and work to streamline legitimate cross-border travel within the Greater Bay Area. Diplomatic efforts to strengthen Macau's role as a platform for China's engagement with Portuguese-speaking and Spanish-speaking countries will also persist, with potential follow-up initiatives stemming from Chief Executive Sam Hou Fai's recent visits to Portugal and Spain.

Critical flashpoints and risk areas: A primary risk area for Macau remains the potential for external interference or activities deemed to challenge national security, given the tightened legal framework. Any such incidents could trigger swift and decisive responses from authorities, potentially impacting civil liberties or international perceptions. Another flashpoint could be economic instability stemming from China's broader economic challenges or unforeseen global events, as highlighted by the impact of Middle East tensions on oil prices and Macau's hospitality sector. While not a direct military flashpoint, significant economic downturns could lead to social unrest, which Macau's national security apparatus is designed to prevent. The Hong Kong-Zhuhai-Macau Bridge and other major border crossings remain critical points for security monitoring and potential vulnerabilities for illicit activities or transit abuses.

Indicators to monitor: Key indicators to monitor include the enforcement and interpretation of Macau's new national security law, particularly in high-profile cases, which will provide insights into the practical application of the legislation. Trends in cross-border traffic and immigration denials will indicate the effectiveness of tightened border controls and the prevalence of transit scheme abuse. Any further regional security exercises or intelligence-sharing agreements involving Macau will signal evolving threats and cooperative responses. Economically, monitoring tourism figures and casino revenues will be crucial, as these are highly sensitive to both internal security stability and broader economic conditions in mainland China and globally. Finally, statements from Macau and Chinese officials regarding Macau's role in the Greater Bay Area and its international platforms will indicate strategic priorities.

Strategic recommendations: Macau should continue to prioritize a holistic approach to national security, balancing robust enforcement with efforts to address socio-economic issues that could undermine stability. Enhancing cybersecurity resilience across critical infrastructure, building upon the lessons from exercises like "STEALTHNET," is paramount given the increasing sophistication of cyber threats. Proactive diplomatic engagement should be maintained to diversify economic partnerships and reinforce Macau's unique role as a bridge for China's international relations, particularly with Lusophone and Hispanic countries. Furthermore, continuous dialogue and coordination with mainland Chinese authorities on border management and security intelligence will be essential for maintaining regional stability and preventing cross-border illicit activities. Investing in economic diversification beyond gaming will also be crucial to build resilience against external economic shocks and reduce reliance on a single industry.
