Security Analysis Report: Taiwan (October 19 - October 26, 2026)

Executive Summary

During the period of October 19-26, 2026, Taiwan faced a heightened and multifaceted security challenge, primarily driven by intensified Chinese "grey-zone" tactics and influence operations ahead of its November 28 local elections. Significant developments included a substantial increase in Chinese cyberattacks and disinformation campaigns, alongside persistent People's Liberation Army (PLA) air and naval incursions into Taiwan's surrounding areas. Concurrently, Taiwan demonstrated a strong commitment to bolstering its defense capabilities by committing a record US$34.5 billion defense budget for 2027 and enhancing military training. Regional security dynamics were further shaped by the large-scale US-Japan "Keen Sword 27" exercises near Taiwan, which Taipei welcomed as a demonstration of regional stability efforts, even as a critical US$14 billion arms sale to Taiwan remained stalled.

Key Security Developments

• Intensified Chinese Disinformation and Cyberattacks
  Taiwan's National Security Bureau (NSB) reported a dramatic increase in Chinese disinformation, with over 2.5 million pieces of disputed or false online information targeting Taiwan in the first nine months of 2026, a 48% rise from the previous year. These campaigns, often utilizing AI-generated content, aim to influence Taiwan's upcoming November 28 local elections by sowing discord and eroding public trust. Chinese cyberattacks on Taiwanese government agencies averaged 2.58 million daily in the first nine months of 2026, with detected threats surging in July to 185.6 million and August to 106.4 million. These attacks targeted academic research, telecommunications, and defense supply chains, potentially for intelligence gathering and harassment.

• Persistent PLA Air and Naval Incursions
  Throughout the week, the PLA maintained a consistent presence around Taiwan. On October 19, Taiwan's Ministry of National Defense tracked five Chinese military aircraft and 15 naval vessels (six PLAN ships and nine official ships), with three aircraft crossing the Taiwan Strait median line. On October 24, one PLAN ship and five official ships were detected, though no aircraft incursions were reported for that specific 24-hour period. Overall, 36 PLA aircraft incursions into Taiwan's Air Defense Identification Zone (ADIZ) were reported in the seven days through October 23, placing activity at the 55th percentile of historical records.

• Highly Destabilizing Chinese Coast Guard Patrols East of Taiwan
  Chinese Coast Guard patrols to the east of Taiwan have been identified as "highly destabilizing" by Randall Schriver, chair of the US Congress' US-China Economic and Security Review Commission. These patrols, which have become regular since June, are seen as an extension of Beijing's legal, political, and information warfare, asserting China's sovereignty claims over the seas around the island.

• Record Defense Budget Commitment
  Taiwan committed a record NT$1.1 trillion (US$34.5 billion) in defense spending for 2027, representing more than 3% of its Gross Domestic Product (GDP). President Lai Ching-te stated that the aim of this increased investment is not to provoke but to deter war, with a long-term goal of reaching 5% of GDP by 2030. This budget reflects Taipei's efforts to modernize its armed forces and strengthen its ability to resist a potential invasion.

• Stalled US$14 Billion US Arms Sale
  A proposed US$14 billion arms sale package from the United States to Taiwan remained unapproved by President Donald Trump, causing concern in Taipei. This package is crucial for Taiwan's multi-layered "T-Dome" air defense system, including Patriot missiles, an automated command and control system, and a 360-degree air defense radar system. The delay is partly attributed to US-China trade negotiations and a review of US weapons stockpiles for other operations.

• US-Japan "Keen Sword 27" Joint Military Exercise
  The largest-ever US-Japan joint military exercise, "Keen Sword 27," commenced on October 19 and will run through October 29, involving approximately 57,000 American and Japanese personnel. The drills focus on the defense of Japan's southwestern islands, with the US Marine Corps deploying its Navy-Marine Expeditionary Ship Interdiction System (NMESIS) to Yonaguni Island, just 110 kilometers from Taiwan. Taiwan's Defense Minister Wellington Koo welcomed these exercises, viewing them as a demonstration of like-minded countries' determination to maintain regional peace and stability.

• Taiwanese Army Adopts Unscripted Combat Training
  Taiwan's army introduced a new format of unscripted combat training, replacing traditional scenario-based programs, to enhance troop combat readiness against the military threat from China. This nine-week program includes intensive live-fire exercises and integrates laser engagement systems and the Team Awareness Kit for real-time intelligence exchange.

• Crackdown on China-Linked Transnational Repression
  Taiwan's Criminal Investigation Bureau (CIB) issued a warning on October 16 against foreign forces, particularly those linked to China, using private investigators, criminal gangs, or local accomplices for surveillance, intimidation, or violence in Taiwan. This followed suspected cases of illegal tracking of lawmakers and attacks on citizens and foreign residents. Prosecutors also indicted five Taiwanese men on October 21 for allegedly accepting US$14,000 from a PRC individual to injure a comedian critical of the CCP.

• Delivery of FPV Attack Drones to US
  Taiwan-based Thunder Tiger Technology, in partnership with US firms, completed the delivery and acceptance of 1,520 FPV (First-Person View) attack drones to the U.S. Department of Defense under its Drone Dominance Program on October 16. This US$7.6 million procurement highlights Taiwan's role in non-Chinese manufacturing networks for military quadcopters and the growing importance of FPV drones in modern combat.

• China's "Taiwan Recovery Day" Commemorations
  On October 25, China marked the 81st anniversary of its "recovery of Taiwan" with commemorative events across the Taiwan Strait, including symposiums in Fuzhou and gatherings in Taipei. These events, organized by Xinhua News Agency and other entities, reaffirmed Beijing's calls for national reunification and criticized Taiwan's ruling Democratic Progressive Party (DPP) for downplaying historical events.

Geopolitical Impact and Regional Dynamics

The security developments surrounding Taiwan this week underscore the persistent and escalating tensions in the Indo-Pacific, with significant implications for regional stability. China's intensified "grey-zone" tactics, particularly the surge in cyberattacks and disinformation campaigns ahead of Taiwan's local elections, represent a clear attempt to undermine democratic processes and exert influence without direct military confrontation. This cognitive warfare, coupled with continuous PLA air and naval incursions and destabilizing Chinese Coast Guard patrols east of Taiwan, maintains constant pressure on Taipei and challenges the existing status quo in the Taiwan Strait.

The large-scale "Keen Sword 27" joint military exercise between the United States and Japan, involving the deployment of advanced anti-ship missile systems near Taiwan, serves as a robust signal of deterrence and commitment to regional security by major powers. Taiwan's welcoming of these drills highlights its reliance on alliances with like-minded democracies to counter Beijing's assertiveness. However, the stalled US$14 billion arms sale package from the US to Taiwan, reportedly due to US-China trade considerations and US weapons stockpiles, introduces an element of uncertainty and potential vulnerability for Taiwan's defense modernization efforts. This delay could be perceived by Beijing as a weakening of US resolve, potentially emboldening further coercive actions.

China's diplomatic efforts, exemplified by the "Taiwan Recovery Day" commemorations, aim to reinforce its historical claims over Taiwan on the international stage and within its domestic narrative, further complicating cross-strait relations. The broader strategic landscape sees Taiwan actively seeking to deepen cooperation with the US and other Indo-Pacific partners, while also working to secure its supply chains from PRC influence. The increasing involvement of other nations like Australia, Canada, France, Germany, the Netherlands, New Zealand, and the Philippines in the "Keen Sword 27" exercises also points to a growing international recognition of the critical importance of Taiwan Strait stability for global security and economic interests.

Military and Defense Analysis

Taiwan's military posture during this period reflects a determined effort to enhance its asymmetric defense capabilities against a potential Chinese invasion. The commitment of a record US$34.5 billion defense budget for 2027, aiming to exceed 3% of GDP, and President Lai Ching-te's ambitious target of 5% by 2030, signifies a substantial increase in defense spending. This funding is crucial for accelerating modernization programs, including the development of a multi-layered "T-Dome" air defense system, which relies on advanced components like Patriot missiles, automated command and control systems, and 360-degree air defense radar. The ongoing delay in the US$14 billion arms package, however, poses a significant challenge to the timely acquisition and integration of these critical capabilities.

In terms of capability developments, Taiwan is actively seeking to expand its inventory of US-made anti-armor missiles, specifically TOW and Javelin systems, following assessments from recent Han Kuang military exercises that identified gaps in existing stockpiles for large-scale amphibious or mechanized assaults. This focus on anti-armor capabilities aligns with an asymmetric defense strategy designed to inflict heavy costs on an invading force. Furthermore, the Taiwanese army's adoption of a new unscripted combat training format, incorporating intensive live-fire exercises and real-time intelligence tools, demonstrates a commitment to improving troop readiness and adaptability in realistic combat scenarios. The delivery of 1,520 FPV attack drones by a Taiwanese company to the US Department of Defense also highlights Taiwan's burgeoning defense industry and its potential to contribute to modern warfare capabilities, including for its own forces. These efforts collectively aim to create a more resilient and capable defense force, capable of deterring aggression and, if necessary, mounting a credible defense.

Outlook and Forecast

Short-term trends (1-3 months): In the immediate future, leading up to Taiwan's November 28 local elections, the intensity of Chinese cyberattacks and disinformation campaigns is expected to remain high, and potentially increase further. Beijing will likely continue to leverage AI-driven influence operations to sow discord and influence voter preferences. PLA air and naval activities around Taiwan, including median line crossings and Chinese Coast Guard patrols, are also forecast to persist as a form of "grey-zone" coercion. The outcome of the stalled US$14 billion arms sale will be a critical indicator; any approval or further delay will significantly impact Taiwan's defense planning and regional perceptions of US commitment. Taiwan will likely continue its diplomatic efforts to gain international support and participation in global bodies.

Critical flashpoints and risk areas: The Taiwan Strait remains the primary flashpoint, with the constant presence of PLA and PLAN assets, and the potential for miscalculation or escalation during routine patrols or exercises. The east coast of Taiwan and its surrounding maritime zones are emerging as a critical area due to the "highly destabilizing" Chinese Coast Guard patrols, which challenge Taiwan's sovereignty claims. Taiwanese government networks and critical infrastructure are high-risk targets for cyberattacks, especially those related to elections and defense supply chains. The Pratas Islands also remain a point of contention, with Chinese Coast Guard vessels reportedly entering restricted areas around them.

Indicators to monitor: Key indicators to monitor include the volume and sophistication of Chinese cyberattacks and disinformation, particularly targeting election-related infrastructure and public discourse. The frequency and nature of PLA air and naval incursions, especially any significant increase in median line crossings or operations in Taiwan's eastern ADIZ, will be crucial. Developments regarding the US$14 billion arms sale, including any statements from President Trump or the US Congress, will signal the trajectory of US support. Additionally, any further reports of China-linked transnational repression or espionage activities within Taiwan will indicate the breadth of Beijing's influence operations.

Strategic recommendations: Taiwan should prioritize strengthening its cybersecurity defenses through increased investment, talent development, and international collaboration to counter sophisticated Chinese attacks and disinformation. Expediting the integration of advanced air defense systems and anti-armor capabilities, regardless of US arms sale timelines, is paramount for enhancing deterrence. Taiwan should continue to advocate for its participation in international organizations and highlight China's "grey-zone" tactics to maintain international attention and support. Furthermore, strengthening internal resilience against foreign influence, including public education on disinformation, is crucial for safeguarding democratic processes. Diplomatic efforts should focus on urging the US to approve pending arms sales and encouraging continued joint exercises with regional partners to reinforce collective security.
