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

Executive Summary

Taiwan faced a week of heightened security concerns from October 18-25, 2026, marked by significant Chinese military and "gray zone" activities, intensified cyberattacks, and ongoing diplomatic maneuvering. The Ministry of National Defense tracked numerous Chinese military aircraft and naval vessels around the island, including crossings of the Taiwan Strait median line, while the Coast Guard reported extensive maritime harassment by Chinese coast guard, research, and militia ships in Taiwan's contiguous and restricted zones. Concurrently, Taiwan's National Security Bureau revealed a substantial increase in Chinese cyberattacks and disinformation campaigns aimed at influencing upcoming local elections. Amidst these pressures, the US-Taiwan Defense Industry Conference in Virginia underscored continued US support and discussions on Taiwan's defense modernization, even as a significant US arms sale package remains pending approval.

Key Security Developments

• Chinese Military and Naval Incursions: On October 18, Taiwan's Ministry of National Defense (MND) tracked two Chinese military aircraft, five naval vessels, and nine official ships, with two People's Liberation Army (PLA) aircraft crossing the Taiwan Strait median line in the northern and central air defense identification zones. This is part of a broader pattern, with Taiwan tracking Chinese aircraft 115 times and ships 208 times so far this month, indicating a sustained increase in "gray zone" tactics since September 2020. The significance lies in China's continuous probing of Taiwan's defenses and its assertion of sovereignty through persistent military presence.

• Extensive Maritime Harassment by Chinese Vessels: Taiwan's Coast Guard Administration (CGA) reported on October 18 that 12 Chinese Coast Guard (CCG) and PRC research ships, along with four PRC fishing boats, simultaneously harassed Taiwanese vessels or crossed Taiwan's maritime boundaries in areas including eastern Hualien, southern Pingtung, southwest Kaohsiung, and the Pratas Islands. The CGA characterized these activities as "hybrid warfare," with PRC research ships like Beidiao 996 and Tansuo 3 entering Taiwan's contiguous zone and only leaving after multiple warnings. This demonstrates China's escalating campaign to erode Taiwan's maritime jurisdiction and response capacity, potentially practicing for a maritime blockade.

• US-Taiwan Defense Industry Conference 2026: The 25th annual US-Taiwan Defense Industry Conference was held from October 18-20, 2026, in Williamsburg, Virginia. This event brought together senior representatives from the Taiwan and US governments to discuss future US defense cooperation, defense procurement, and Taiwan's national security needs. Key sessions focused on updated threat assessments, Taiwan's "whole-of-society resilience" approach, force planning evolution, lessons from conflicts in Ukraine and Iran, and the interplay between foreign procurement and domestic production capacity. The conference highlights ongoing strategic dialogue and commitment to strengthening Taiwan's defense capabilities.

• US Army's New Strategy to Counter China: The US Army unveiled its October 2026 operational guidance for a potential conflict with China in the Indo-Pacific on October 18. 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, specifically mentioning support for Taiwan in a conflict. The guidance also includes a hypothetical Taiwan contingency scenario, examining the deployment of US Army strike capabilities from northern Luzon in the Philippines. This signifies a clear US strategic focus on deterring Chinese aggression against Taiwan and enhancing regional military readiness.

• Japan-US "Keen Sword" Military Exercise: The United States and Japan launched their largest-ever "Keen Sword" joint military exercise from October 19-29, involving approximately 57,000 personnel. The exercise includes Japan's first deployment of its new Type 25 surface-to-ship missile system outside its permanent base and the US Marine Corps deploying its Navy-Marine Expeditionary Ship Interdiction System (NMESIS) to Yonaguni Island, just 110 kilometers from Taiwan. These maneuvers are designed to test rapid deployment and anti-ship capabilities across Japan's southwestern island chain, a critical area for a potential Taiwan Strait conflict. Taiwan's Minister of National Defense Wellington Koo praised the inclusion of a Taiwan-related contingency scenario in these exercises.

• Escalation of Chinese Cyberattacks and Disinformation: Taiwan's National Security Bureau (NSB) reported on October 21 that China has significantly increased cyberattacks and disinformation campaigns ahead of Taiwan's local elections on November 28. Taiwan was hit with an average of 2.6 million cyberattacks daily in the first nine months of 2026, with a notable intensification since June. These attacks target academic, telecommunications, and defense supply chains, aiming to interfere with government operations, undermine international cooperation, and steal sensitive technologies. China is also reportedly using AI to generate content and fake polls to influence voter preferences and sow distrust in Taiwan's democracy.

• Taiwanese Government Urges Cybersecurity Patches: On October 22, Taiwan's Administration for Cybersecurity urged government agencies and businesses to immediately install security updates for PHP, Node.js, and Go software after vulnerabilities were disclosed. These vulnerabilities could allow remote code execution or interception of digital certificates, highlighting the ongoing threat landscape and the need for proactive defense against cyber threats.

• Pending US$14 Billion US Arms Sale to Taiwan: Taiwan continues to await US President Donald Trump's approval of a US$14 billion arms sale package, which includes Patriot missiles, an automated command and control system, and a 360-degree air defense radar system. This package is crucial for Taiwan's "T-Dome" multilayered air defense system. The delay is attributed to Trump's efforts to ease trade tensions with China, with President Xi Jinping having warned against further large arms sales to the island. This situation underscores the complexities of US-China relations impacting Taiwan's defense acquisitions.

• Taiwan Army Rolls Out Unscripted Combat Training: On October 25, the Taiwan Army implemented its new Combat Training Center 2.0 program, moving away from traditional scripted exercises to more realistic, unscripted training. This program emphasizes coordinated operations across different units, aiming to improve agility, interoperability, and civil-military coordination. This shift reflects Taiwan's commitment to enhancing combat readiness and adapting to modern warfare scenarios.

• China's Renewed Push for Taiwan Reunification: On October 23, China used an event in Nairobi, Kenya, to mark the 81st anniversary of Taiwan's restoration to China and renew its push for reunification. Chinese Ambassador to Kenya Guo Haiyan reaffirmed Beijing's "One-China principle" and cited Kenya's support for China's efforts to achieve national reunification. This diplomatic effort underscores China's unwavering long-term goal regarding Taiwan and its attempts to garner international support for its position.

• Taiwan's Acquisition of VTOL Drones: On October 18, it was reported that Taiwan is looking to acquire 292 MQ-35A V-BAT vertical takeoff and landing (VTOL) surveillance drones for its navy and coast guard. If finalized, this contract would make Taiwan one of the largest operators of V-BAT drones outside the US, significantly enhancing its surveillance capabilities. The Coast Guard Administration has already budgeted NT$1.2 billion (US$37.1 million) for 12 drones, with the navy planning to spend NT$36 billion for 280 more.

• Taiwanese Legislative Yuan Committee Freeze on Defense Procurement: 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 Foreign Affairs and National Defense Committee. This legislative hold is stalling the procurement of critical systems like the Taiwan Tactical Mission Network and the Team Awareness Kit, which are essential for establishing common operational pictures across field formations. This internal political hurdle could impact Taiwan's immediate defense modernization efforts.

Geopolitical Impact and Regional Dynamics

The period of October 18-25, 2026, highlights a sustained and escalating pattern of Chinese pressure on Taiwan, which significantly impacts regional stability. China's "gray zone" tactics, involving frequent military and maritime incursions into Taiwan's air defense identification zone and contiguous waters, are designed to normalize its presence and gradually erode Taiwan's effective control without triggering open conflict. These actions, particularly the extensive maritime harassment by coast guard, research, and militia vessels, are perceived by Taiwanese officials as "hybrid warfare" and potential rehearsals for a maritime blockade, directly threatening vital shipping lanes and supply routes in the Western Pacific. This aggressive posture not only destabilizes the Taiwan Strait but also puts pressure on neighboring countries like Japan and the Philippines, who share concerns about China's expansive territorial claims and maritime activities.

Relations with major powers, particularly the United States and China, remain central to Taiwan's security. The US-Taiwan Defense Industry Conference in Virginia reaffirmed Washington's commitment to Taiwan's defense, with discussions focusing on threat assessments and defense cooperation. The US Army's new operational guidance, explicitly outlining strategies to counter China and support Taiwan in a conflict, further underscores this commitment. However, the pending US$14 billion arms sale to Taiwan, reportedly delayed by US President Donald Trump's efforts to ease trade tensions with China, introduces an element of uncertainty regarding the timeliness of crucial defense acquisitions. This delay, coupled with China's warnings against such sales, illustrates the delicate balance in US-China relations and its direct implications for Taiwan's security.

The US-Japan "Keen Sword" military exercise, involving the deployment of advanced anti-ship missile systems to islands near Taiwan, demonstrates a growing strategic convergence between Washington and Tokyo in deterring Chinese aggression. This joint exercise, the largest ever, sends a strong signal to Beijing about the collective resolve to maintain regional stability and freedom of navigation. Taiwan's positive reception of the inclusion of a Taiwan-related contingency scenario in these drills highlights the increasing alignment of security interests among democratic partners in the Indo-Pacific. Meanwhile, China's diplomatic efforts, such as the event in Nairobi to promote its "One-China principle" and reunification agenda, reflect its ongoing campaign to isolate Taiwan internationally and garner support for its territorial claims. The intensified Chinese cyberattacks and disinformation campaigns targeting Taiwan's elections further complicate the geopolitical landscape by attempting to undermine Taiwan's democratic processes and sow internal discord.

Military and Defense Analysis

Taiwan's military and defense posture during this period reflects a concerted effort to enhance its capabilities in the face of persistent Chinese threats. The Taiwan Army's implementation of the new Combat Training Center 2.0 program on October 25 signifies a significant shift towards more realistic and unscripted training. This program, which abandons traditional scorecards and transforms evaluators' roles, aims to improve coordinated operations across different units, address historical weaknesses in interoperability, and strengthen civil-military coordination. This modernization in training doctrine is crucial for preparing Taiwan's forces for complex, real-world scenarios, particularly those involving "gray zone" tactics and potential amphibious assaults.

In terms of defense acquisitions and capability developments, Taiwan is actively pursuing advanced systems to bolster its deterrence. The reported plan to acquire 292 MQ-35A V-BAT vertical takeoff and landing (VTOL) surveillance drones for the navy and coast guard is a notable development. This acquisition, if finalized, would significantly enhance Taiwan's intelligence, surveillance, and reconnaissance (ISR) capabilities, providing crucial situational awareness in its maritime and border security efforts. However, the ongoing delay in the US President's approval of a US$14 billion arms sale package, which includes critical Patriot missiles and air defense systems, remains a concern. While Taiwan has committed a record NT$1.1 trillion (US$34.5 billion) in defense spending for 2027, exceeding 3% of its GDP, the timely delivery of these advanced foreign systems is vital for its multi-layered air defense and overall defensive resilience. The legislative freeze on over 150 defense budget items, including funds for tactical ground network procurement, also presents an internal challenge to accelerating modernization programs.

The US-Taiwan Defense Industry Conference provided a platform to discuss Taiwan's force planning evolution, examining how changes to doctrine, training, and organizational structures could align to address a broad range of threat scenarios. Discussions on the interplay between foreign procurement and expanded domestic production capacity are critical for Taiwan's long-term deterrence goals and supply chain security. The lessons learned from conflicts in Ukraine and Iran are also being integrated into Taiwan's defense policies and national security strategies, indicating a proactive approach to adapting to evolving threats. Overall, Taiwan is demonstrating a strong commitment to modernizing its military, but external factors like US arms sale approvals and internal legislative processes continue to influence the pace and scope of its defense build-up.

Outlook and Forecast

Short-term trends (1-3 months) indicate a continued high level of Chinese military and "gray zone" pressure on Taiwan, particularly in the lead-up to Taiwan's local elections on November 28, 2026. We can expect an intensification of Chinese cyberattacks and disinformation campaigns, leveraging AI to influence voter preferences and sow discord within Taiwanese society. Maritime incursions by Chinese coast guard, research, and militia vessels are likely to persist, testing Taiwan's response capabilities and potentially rehearsing for a blockade. Taiwan will likely continue its efforts to enhance combat readiness through unscripted training and pursue defense acquisitions, though the approval of the US$14 billion arms package remains a critical near-term indicator. The US and Japan will likely continue joint military exercises in the region, signaling deterrence to China.

Critical flashpoints and risk areas primarily revolve around the Taiwan Strait and Taiwan's contiguous and restricted maritime zones. Any miscalculation or aggressive maneuver by Chinese military or paramilitary forces could quickly escalate tensions. The ongoing Chinese "hybrid warfare" tactics, combining military and non-military assets, pose a continuous risk of destabilization. The upcoming local elections in Taiwan are a significant flashpoint, as China's intensified influence operations could lead to increased internal political polarization and potentially impact the election outcomes, which Beijing might interpret as an opportunity for further coercion. The South China Sea, where China is also intensifying its maritime coercion against the Philippines, remains a broader regional risk area that could indirectly affect Taiwan's security posture.

Indicators to monitor include the frequency and nature of Chinese military aircraft and naval vessel incursions, particularly crossings of the Taiwan Strait median line and activities in Taiwan's eastern waters. The approval and delivery timeline of the US$14 billion arms sale to Taiwan will be a crucial indicator of the strength of US commitment and Taiwan's ability to acquire critical defense assets. Monitoring the scale and sophistication of Chinese cyberattacks and disinformation campaigns, especially those utilizing AI, will provide insights into Beijing's evolving tactics for political interference. Furthermore, observing the outcomes of Taiwan's internal legislative processes regarding defense budget approvals will be important for assessing the pace of its defense modernization. Any significant shifts in rhetoric or actions from US President Trump regarding Taiwan, especially in the context of US-China trade talks, should also be closely watched.

Strategic recommendations for Taiwan should focus on accelerating the development of asymmetric warfare capabilities, particularly in areas like anti-ship missiles, advanced surveillance drones, and resilient command and control systems, to deter a potential invasion or blockade. Strengthening cybersecurity defenses and public awareness campaigns against disinformation are paramount to safeguard democratic processes and national cohesion. Taiwan should continue to advocate for the timely delivery of approved and pending US arms sales, while also diversifying its defense procurement where possible to reduce reliance on a single supplier. Diplomatically, Taiwan should continue to deepen security cooperation with like-minded partners, such as the US and Japan, to enhance regional deterrence and maintain a united front against Chinese coercion. Internally, resolving legislative bottlenecks in defense spending is crucial to ensure that modernization programs proceed without undue delay.
