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

Executive Summary

Taiwan faced a week of heightened security challenges and proactive defense measures from October 16 to October 23, 2026. Significant developments included intensified Chinese military "gray zone" tactics, a notable increase in state-sponsored cyberattacks and disinformation campaigns targeting upcoming elections, and robust responses from Taiwan's defense forces. Diplomatic tensions escalated with China sanctioning ministers from Taiwan's diplomatic allies, while Taiwan continued to strengthen its defense capabilities through strategic acquisitions and joint exercises with key partners. The period underscored Taiwan's commitment to self-reliance in security while navigating complex geopolitical dynamics with China, the United States, and Japan.

Key Security Developments

• Military Activities and Exercises in the Taiwan Strait
  The People's Republic of China (PRC) continued its "gray zone" tactics, with Taiwan's Ministry of National Defense tracking 8 Chinese military aircraft, 9 naval vessels, and 7 official ships between October 15 and October 16. All Chinese military aircraft crossed the Taiwan Strait median line in Taiwan's northern and southwestern air defense identification zones. By October 19, Taiwan tracked 5 Chinese military aircraft and 15 ships, with three aircraft crossing the median line. On October 20, 14 Chinese military aircraft and 14 ships were tracked, with eight aircraft crossing the median line in northern, central, southwestern, and eastern ADIZs. These consistent incursions are part of China's strategy to incrementally increase its military presence around Taiwan without resorting to direct force.

• Chinese Aircraft Carrier Drills in Western Pacific
  The PRC deployed its Liaoning aircraft carrier in the Western Pacific for "routine" drills on October 14 and 15, including launching aircraft in Taiwan's eastern Exclusive Economic Zone (EEZ). While described as minor, these drills are seen as a warning to Taiwan following President Lai's recent National Day speech. This activity demonstrates China's growing naval projection capabilities and its intent to assert influence in waters surrounding Taiwan.

• US-Japanese "Keen Sword" Joint Military Exercise
  The United States and Japan commenced their largest-ever "Keen Sword" joint military exercise from October 19 to October 29, involving approximately 57,000 personnel. A key component of these maneuvers includes the deployment of anti-ship missiles by the U.S. Marine Corps and Japan's Self-Defense Force to Yonaguni Island, located approximately 110 kilometers from Taiwan. This marks the first such U.S. military deployment to Yonaguni and is intended to test rapid deployment and anti-ship capabilities in a critical maritime chokepoint near Taiwan, likely concerning the PLA.

• Taiwan's "Lu Sheng" Military Exercises
  Taiwan conducted ten-day "Lu Sheng" military exercises in the north of the island from October 14 to October 23. These exercises involved the 269th Mechanized Infantry Brigade (Taoyuan) and the 564th Armored Brigade (Kaohsiung), simulating 24-hour combat scenarios for prolonged territorial defense against a potential Chinese attack. Troops utilized command and control systems, reconnaissance and attack drones, and new equipment like U.S.-based M1A2T Abrams combat cars, aiming to enhance operational resistance and realistic combat training.

• Chinese Maritime Harassment and Coast Guard Confrontations
  On October 18, Taiwan's Coast Guard reported driving away 16 Chinese vessels, including coast guard ships, research vessels, and fishing boats, engaged in "unusually large" and simultaneous "maritime harassment" operations near Taiwan's main island and the Pratas Islands. Taiwan characterized these actions as "hybrid warfare" and accused Beijing of attempting to unilaterally alter the status quo in the Taiwan Strait. Separately, on October 21, Taiwan's Coast Guard reported a standoff with a Chinese Coast Guard ship that had entered restricted waters near the Taiwan-controlled Pratas Islands, with both sides broadcasting warnings.

• Escalation of Chinese Cyberattacks and Disinformation
  Taiwan's National Security Bureau (NSB) warned of a significant increase in Chinese cyber operations and online influence campaigns aimed at disrupting the island's November 28 local elections. The Government Service Network (GSN) recorded an average of 2.58 million attempted cyber intrusions daily from January to September 2026, with July alone seeing 185.6 million attempts. Chinese hackers targeted academic research, telecommunications, and defense suppliers, utilizing AI-driven disinformation to undermine government confidence and influence voters.

• Taiwan's "Red-Free Supply Chain" Policies
  The Taiwanese government continued to enforce policies aimed at eliminating dependencies on PRC-made software and components in critical technology supply chains. This initiative, designed to protect national security and prevent sabotage, was highlighted by a case where Taoyuan District Court prosecutors alleged a Taiwanese defense contractor, Jiin Meng Industry Co., used prohibited PRC-made chips and camera lenses in military drones.

• China Sanctions Taiwan's Diplomatic Allies
  In a new diplomatic pressure tactic, the Chinese government sanctioned two government ministers from Taiwan's diplomatic allies: Belizean Foreign Minister Francis Fonseca and Paraguayan Minister of Information Gustavo Villate on October 17. These sanctions prevent them and their families from doing business in China, signaling an attempt to pressure countries to switch diplomatic recognition from Taiwan to China.

• Defense Acquisitions: VTOL Drones and Budget Freezes
  Taiwan is reportedly planning to acquire 292 units of MQ-35A V-BAT vertical takeoff and landing (VTOL) surveillance drones from the US-based defense technology company Shield AI. The Coast Guard Administration has already received 12 drones, with the navy planning to acquire 280 more under a NT$36 billion program. However, on October 19, Taiwan's Ministry of National Defense confirmed that over 150 defense budget items, including $55.0 million allocated for tactical edge command systems, remain frozen pending review by the Legislative Yuan's Foreign Affairs and National Defense Committee.

• US Army's New Strategy to Counter China
  The US Army unveiled its October 2026 operational guidance outlining a new strategy for a potential conflict with China in the Indo-Pacific. This strategy details how US forces could conduct long-range strikes within the First Island Chain, deploy dispersed combat formations, and sustain operations across contested supply routes, explicitly including support for Taiwan in a contingency scenario.

• Taiwan-Europe Security Cooperation Call
  National Security Council Secretary-General Joseph Wu urged Taiwan and Europe to deepen cooperation to safeguard Taiwan's security and Europe's prosperity. Speaking at the Taiwan Forum in Berlin on October 17, Wu emphasized that peace in the Taiwan Strait is vital to European security and economic interests and called for greater cooperation in semiconductors, artificial intelligence, and cybersecurity.

Geopolitical Impact and Regional Dynamics

The period from October 16 to 23, 2026, saw a continuation and intensification of geopolitical tensions surrounding Taiwan, significantly impacting regional stability. China's persistent "gray zone" military activities, including frequent air and naval incursions across the Taiwan Strait median line and aircraft carrier drills in the Western Pacific, serve to normalize its military presence near Taiwan and test Taipei's response capabilities. These actions are a clear demonstration of Beijing's resolve to assert its sovereignty claims over Taiwan and its surrounding waters, contributing to an elevated risk of miscalculation in the region. The "unusually large" Chinese maritime harassment operations near Taiwan and the Pratas Islands, characterized by Taiwan as "hybrid warfare," further underscore China's multi-faceted approach to pressure the island.

Relations with major powers remain central to Taiwan's security. The joint US-Japanese "Keen Sword" exercise, particularly the deployment of anti-ship missiles to Yonaguni Island, a mere 110 kilometers from Taiwan, signals a strengthening of deterrence capabilities by Taiwan's democratic partners. This move, likely aimed at containing the PLA's surface fleet and denying control of critical maritime chokepoints, reinforces the US-Japan alliance's commitment to regional security and Taiwan's defense. However, uncertainty regarding the approval of a $14 billion US arms package and the broader implications of US-China trade talks under the current US administration introduce an element of unpredictability into Washington's commitment to Taiwan's defense.

China's new tactic of sanctioning ministers from Taiwan's diplomatic allies (Belize and Paraguay) represents an escalation in its efforts to isolate Taiwan internationally and pressure its remaining partners to switch recognition. This diplomatic coercion, coupled with a surge in Chinese cyberattacks and AI-driven disinformation campaigns targeting Taiwan's upcoming local elections, highlights Beijing's comprehensive strategy to undermine Taiwan's democratic processes and societal resilience. Taiwan's proactive measures, such as developing "red-free supply chains" and seeking closer security cooperation with Europe, demonstrate its efforts to counter Chinese influence and diversify its strategic partnerships, thereby shaping a more resilient, albeit tense, regional strategic landscape.

Military and Defense Analysis

Taiwan's military and defense posture during this period reflects a dual strategy of enhancing self-defense capabilities and strengthening alliances. The ongoing "Lu Sheng" military exercises, simulating prolonged, 24-hour combat scenarios with advanced equipment like M1A2T Abrams tanks and drones, demonstrate Taiwan's commitment to realistic training and developing a robust "deep defense" strategy against a potential invasion. This focus on asymmetric warfare capabilities is further evidenced by the planned acquisition of 292 MQ-35A V-BAT VTOL surveillance drones, which are crucial for reconnaissance and maintaining operational capability even if command structures are disrupted. The delivery of 12 V-BAT drones to the Coast Guard underscores the immediate efforts to bolster maritime surveillance.

Despite these modernization efforts, challenges persist in defense acquisitions and spending. While the legislature approved a NT$780 billion defense spending package earlier in May 2026, the freezing of over 150 defense budget items, including $55.0 million for tactical edge command systems, by the Legislative Yuan on October 19, indicates potential internal political hurdles or bureaucratic delays in implementing critical defense programs. This delay could impact Taiwan's ability to rapidly acquire and integrate essential combat capabilities. The arrival of the first two F-16V Block 70 fighter jets on October 2, while outside the immediate reporting window, provides a crucial boost to Taiwan's air force, enhancing its ability to counter advanced Chinese aircraft. Overall, Taiwan is actively working to modernize its forces and improve its ability to deter and, if necessary, defend against Chinese aggression, but faces ongoing pressure from Beijing's military expansion and internal political dynamics affecting defense procurement.

Outlook and Forecast

Short-term trends (1-3 months): In the immediate future, Taiwan can expect a continuation, and likely an intensification, of China's "gray zone" tactics, particularly in the lead-up to Taiwan's local elections on November 28. This will manifest as frequent incursions by military aircraft and naval vessels across the Taiwan Strait median line and around the Pratas Islands, aiming to exert psychological pressure and test Taiwan's response thresholds. Cybersecurity threats and AI-driven disinformation campaigns will also escalate significantly, targeting the elections to sow discord and undermine public trust in the government. Taiwan will likely continue its "Lu Sheng" exercises and other defensive drills to maintain readiness. Diplomatic pressure from China on Taiwan's allies is also expected to persist, potentially leading to further sanctions or attempts to poach diplomatic partners.

Critical flashpoints and risk areas: The Taiwan Strait remains the primary flashpoint, with the risk of accidental escalation due to frequent military and coast guard encounters. The Pratas Islands are another critical area, as demonstrated by recent Chinese maritime harassment and coast guard confrontations, indicating a potential for increased Chinese assertiveness in this strategically important region. The upcoming local elections present a significant risk area for cyberattacks and information warfare, which could destabilize Taiwan's domestic political landscape. Furthermore, any perceived shift in the US's commitment to Taiwan's defense, particularly regarding delayed arms sales, could embolden Beijing and create a dangerous vacuum.

Indicators to monitor: Key indicators to monitor include the frequency and scale of Chinese military and coast guard incursions, especially any new patterns or deployments. The nature and impact of Chinese cyberattacks and disinformation campaigns leading up to the elections will be crucial. Progress on Taiwan's defense budget items, particularly the unfreezing of funds for tactical command systems, will indicate the effectiveness of its defense modernization. Any further sanctions by China against Taiwan's diplomatic allies or attempts to switch diplomatic recognition should be closely watched. Finally, statements and actions from the US and Japan regarding their security commitments to Taiwan, including the progress of the "Keen Sword" exercises and future arms sales, will be vital in assessing regional stability.

Strategic recommendations: Taiwan should continue to invest heavily in asymmetric warfare capabilities, focusing on mobile, survivable, and precision-strike systems that can deter or counter a larger invading force. Expediting the procurement and deployment of advanced drones and anti-ship missiles is paramount. Strengthening cybersecurity defenses and developing robust counter-disinformation strategies are critical to safeguarding democratic processes and national resilience, especially during election periods. Diplomatically, Taiwan should continue to cultivate and expand its relationships with like-minded democracies, particularly in Europe, to build a broader coalition against Chinese coercion and advocate for its international participation. Internally, addressing legislative bottlenecks in defense spending is crucial to ensure timely acquisition of necessary military hardware.
