Security Analysis Report: Taiwan (July 23, 2026 - July 30, 2026)

Executive Summary

The period from July 23 to July 30, 2026, saw a continued escalation of military and "grey zone" pressure from China on Taiwan, coupled with significant developments in Taiwan's defense planning and international support. China conducted live-fire drills in the Taiwan Strait and maintained daily incursions of military aircraft and naval vessels, with a notable increase in maritime patrols east of Taiwan, raising concerns about a potential blockade rehearsal. Concurrently, Taiwan announced robust annual military exercises focused on wartime resilience, including relocating arms production and enhancing drone capabilities. The United States reaffirmed its commitment to Taiwan's security through legislative actions on defense funding and continued diplomatic engagement, despite ongoing delays in a major arms package approval. Cybersecurity threats, particularly ransomware, also remained a critical concern, with warnings issued by Taiwan's digital authorities.

Key Security Developments

• Chinese Live-Fire Drills in Taiwan Strait
  China announced and conducted two days of live-fire exercises in the Taiwan Strait from July 23 to July 24, running from 6 a.m. to 6 p.m. each day, in waters near its southeastern Fujian province. These drills, located less than 12 kilometers from the coast of Fujian, were part of Beijing's strategy to maintain constant military pressure on Taiwan without initiating open conflict. Taiwan's Ministry of Foreign Affairs condemned these exercises.

• Heightened Chinese Military Incursions
  Taiwan's Ministry of National Defense (MND) reported heightened Chinese military activity, tracking 21 People's Liberation Army (PLA) aircraft, 6 naval vessels, and 2 official ships around Taiwan between 6 a.m. on Wednesday and 6 a.m. on Thursday, July 23. Twenty of the 21 aircraft crossed the Taiwan Strait median line and entered Taiwan's northern and southwestern Air Defense Identification Zone (ADIZ). This activity is consistent with China's "grey zone" tactics, which have seen 163 Chinese military aircraft and 243 ships tracked so far this month (July 2026).

• Increased Chinese Maritime Patrols East of Taiwan
  China's coastguard and civilian fleet expanded their presence in the waters east of Taiwan throughout June and July, staging multiple patrols and "special maritime law enforcement operations." Analysts view this as part of China's "boa constrictor strategy" to squeeze Taiwan and potentially rehearse a containment or blockade strategy, cutting off the island from external trade and assistance. These activities extended into waters overlapping with Taiwan's Exclusive Economic Zone (EEZ) and near the uninhabited Taiwan-controlled Dongsha Islands (Pratas Islands).

• Taiwan's Han Kuang War Games Focus on Resilience
  On July 28, Taiwan's Ministry of National Defense announced its annual Han Kuang war games, scheduled for August 5-14, will include drills testing the relocation of weapons production lines and the conversion of civilian factories to sustain combat operations under Chinese attack. Major General Lu Wen-yuan, head of the Joint Operations Division, stated these drills assume Chinese forces would use routine annual joint military exercises as cover for a large-scale landing.

• Drone and Counter-Drone Drills in Han Kuang Exercises
  The upcoming 42nd Han Kuang military exercises will specifically incorporate drone warfare and counter-drone operations, including battlefield reconnaissance, joint target acquisition, integrated joint fire strikes, and counter-drone measures. This highlights Taiwan's adaptation to modern warfare lessons from conflicts like the Russia-Ukraine war.

• Anti-Blockade Drills for Maritime Security
  As part of the Han Kuang exercises, Taiwan will conduct anti-blockade drills to secure maritime transportation routes and replenish critical resources. These drills will involve coordinated operations between the Navy and the Coast Guard Administration to secure shipping lanes and escort vital supplies.

• US House Passes Defense Budget with Taiwan Funding
  On July 23, the US House of Representatives passed a record US$1.15 trillion defense budget for 2027, which includes funding to help Taipei bolster its self-defense capabilities. The budget also supports bilateral drone development and a plan to bring Taiwan into the 2028 Rimac naval exercise. Separately, on July 15, the US House passed a bill including $500 million in Foreign Military Financing for Taiwan.

• US Secretary of State Reaffirms Unchanged Taiwan Policy
  On July 23, US Secretary of State Marco Rubio reiterated that the US policy toward Taiwan remains unchanged and expressed disagreement with China's recent deployment of coast guard vessels near Taiwan, stating these actions undermine regional stability. He also clarified that arms sales to Taiwan are not tied to any potential visit by Chinese leader Xi Jinping to the US.

• Taiwan-US Partnership Flourishing
  On July 26, Lei Yen-feng, director-general of the Taipei Economic and Cultural Office in Chicago, stated that Taiwan-US relations continue to flourish, with the US Departments of State, Commerce, and Agriculture encouraging deeper cooperation with Taiwan across all 50 states. Taiwan seeks to strengthen bilateral cooperation in AI supply chains, digital infrastructure, critical minerals, and drone supply chains.

• Cybersecurity Agency Warns of Ransomware Threats
  On July 27, Taiwan's Ministry of Digital Affairs warned that ransomware attacks are a growing threat to businesses, with hackers increasingly using data theft and generative AI to expand their attacks. The agency noted that at least five Taiwanese companies had disclosed ransomware attacks this year (2026) in sectors including paper manufacturing, biotechnology, and semiconductors.

• Taiwan's Need for an AI Cyber Shield
  A commentary published on July 29 highlighted Taiwan's urgent need for an AI cyber shield to defend against constant Chinese intrusions, which reportedly amount to 2.6 million attempts daily against its critical infrastructure. Taiwan is already working on defense AI projects, such as the T-Dome integrated air, missile, and intelligence defense system, and an AI tool to pilot multiple unmanned systems.

• Forbes Urges Approval of US$14 Billion Arms Sale
  On July 29, Forbes magazine urged US President Donald Trump to approve a US$14 billion arms sale package for Taiwan without further delay. The package, which includes anti-ship missiles and ammunition, is crucial for Taiwan's "porcupine strategy" to make any invasion prohibitively costly. President Trump has reportedly been holding off approval of this package since May.

Geopolitical Impact and Regional Dynamics

The period from July 23 to July 30, 2026, underscored the persistent and intensifying geopolitical tensions surrounding Taiwan, primarily driven by China's assertive actions. Beijing's live-fire drills in the Taiwan Strait and daily military incursions serve as a clear demonstration of its resolve to assert sovereignty, directly impacting regional stability. The increased Chinese maritime patrols east of Taiwan, interpreted as a potential rehearsal for a blockade, represent a significant escalation in "grey zone" tactics designed to wear down Taiwan's resources and morale without triggering open conflict. This "boa constrictor strategy" poses a direct threat to Taiwan's economic lifelines and raises alarm among regional partners about China's long-term intentions.

Relations with major powers remain a critical dynamic. The United States, through legislative actions, continued to signal strong support for Taiwan's defense capabilities, with the House passing a defense budget that includes funding for Taiwan's self-defense and participation in multilateral exercises. US Secretary of State Marco Rubio's reaffirmation of an unchanged US Taiwan policy and his disagreement with China's coast guard patrols underscore Washington's commitment to regional stability and its opposition to unilateral changes to the status quo. However, the ongoing delay in approving a major US$14 billion arms package for Taiwan introduces a degree of uncertainty and raises concerns about US credibility, as highlighted by Forbes magazine.

China's interactions with other regional players also reflect the heightened tensions. At ASEAN-related foreign ministers' meetings in Manila, China strongly rebutted Japan's remarks on the Taiwan question and the South China Sea, urging external forces to cease stirring tensions. This indicates China's sensitivity to international commentary on Taiwan and its efforts to isolate the issue as an internal affair. The ongoing review of Papua New Guinea's relationship with Taiwan, potentially influenced by China's growing economic ties in the Pacific, also illustrates Beijing's broader diplomatic efforts to diminish Taiwan's international space. These dynamics collectively reinforce the perception of Taiwan as a central flashpoint in the Indo-Pacific, with implications for the strategic balance between the US, China, and their respective allies.

Military and Defense Analysis

Taiwan's military and defense posture during this period is characterized by a proactive approach to enhancing resilience against a potential Chinese invasion, particularly through its upcoming Han Kuang exercises. The focus on simulating the wartime relocation of arms production lines and converting civilian factories for "whole-system assembly" demonstrates a strategic shift towards ensuring industrial output and combat sustainment even if primary military facilities are compromised. This reflects a recognition of the need for a robust, distributed defense industrial base capable of enduring initial strikes.

A significant development is the emphasis on drone warfare and counter-drone operations within the Han Kuang drills. This includes battlefield reconnaissance, joint target acquisition, and integrated joint fire strikes, indicating Taiwan's commitment to leveraging unmanned systems as a critical component of modern warfare, drawing lessons from recent global conflicts. Concurrently, the inclusion of anti-blockade drills involving joint operations between the Navy and Coast Guard to secure maritime transportation routes and replenish critical resources directly addresses China's escalating "grey zone" maritime pressure, which analysts fear could lead to a full-scale blockade. These drills aim to bolster Taiwan's ability to maintain essential supplies as an island nation.

Defense spending trends and capability developments are also influenced by external support. The US House of Representatives' approval of a US$1.15 trillion defense budget for 2027, which includes funding for Taiwan's self-defense capabilities and bilateral drone development, signals continued US commitment to enhancing Taiwan's military modernization. The proposed inclusion of Taiwan in the 2028 Rimac naval exercise would further integrate Taiwan into multilateral defense frameworks and improve interoperability. However, the delay in the approval of a substantial US$14 billion arms package, including anti-ship missiles, remains a critical concern for Taiwan's immediate defense acquisition needs, particularly for its "porcupine strategy" designed to deter invasion by making it prohibitively costly.

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 "grey zone" tactics. This will manifest as persistent daily incursions by PLA aircraft and naval vessels, including crossings of the Taiwan Strait median line, and further expansion of Chinese coastguard and civilian maritime patrols, particularly in the waters east of Taiwan. These actions are designed to test Taiwan's response capabilities, strain its resources, and normalize China's asserted jurisdiction. Taiwan's upcoming Han Kuang exercises in August will be a critical period, as China may react with further demonstrative military actions. The focus of these exercises on wartime resilience, drone warfare, and anti-blockade measures will be closely watched by both Beijing and international observers.

Critical flashpoints and risk areas: The Taiwan Strait remains the primary flashpoint, with Chinese live-fire drills and routine incursions maintaining a high level of tension. The waters east of Taiwan, including Taiwan's Exclusive Economic Zone and near the Pratas Islands, are emerging as a critical risk area due to increased Chinese maritime patrols that could escalate into a de facto blockade or quarantine. Any miscalculation or aggressive maneuver in these congested maritime and air spaces could quickly lead to an unintended escalation. Furthermore, cyberattacks against Taiwan's critical infrastructure will continue to be a significant threat, with the potential for disruptive or paralyzing effects, especially with the increasing use of AI by hackers.

Indicators to monitor: Key indicators to monitor include the frequency, scale, and geographic scope of Chinese military and maritime "grey zone" activities, particularly any sustained presence or exercises that explicitly simulate a blockade of Taiwan. The outcomes and international reactions to Taiwan's Han Kuang exercises will also be important. Progress on US arms sales, specifically the approval of the delayed US$14 billion package, will signal the strength of Washington's commitment. Developments in Taiwan's domestic defense industry, especially in drone production and cybersecurity infrastructure, will indicate its self-reliance efforts. Finally, any shifts in diplomatic rhetoric or actions from key regional players (e.g., Japan, the Philippines) regarding Taiwan's security will be crucial.

Strategic recommendations: Taiwan should continue to prioritize and accelerate its asymmetric defense capabilities, focusing on mobile, survivable, and precision strike systems, particularly anti-ship missiles and advanced drone technologies. Investment in cybersecurity defenses, including the development of an AI cyber shield, is paramount to protect critical infrastructure from persistent Chinese cyber threats. Taiwan should also enhance its civilian resilience and whole-of-society defense planning, as demonstrated by the Han Kuang exercises, to ensure continuity of government and essential services under duress. Diplomatically, Taiwan should continue to strengthen its partnerships with like-minded democracies, advocating for clear and consistent international support against coercion, while also engaging in multilateral exercises to improve interoperability and demonstrate its commitment to regional security.
