Security Analysis Report: Taiwan (February 21, 2026 - February 28, 2026)

Executive Summary

The period from February 21 to February 28, 2026, saw Taiwan navigating a complex security landscape characterized by persistent Chinese military pressure, significant cyber threats, and evolving diplomatic dynamics. A critical development was the finalization of the U.S.-Taiwan Agreement on Reciprocal Trade (ART) on February 12, which, alongside defense and technology agreements, aimed to solidify a "triangular fortress" of cooperation. However, this was immediately complicated by reports of a delayed U.S. arms package to Taiwan, reportedly to facilitate an upcoming U.S.-China summit. Simultaneously, Taiwan faced continuous "gray zone" military incursions from China and a stark warning about sophisticated Chinese cyber warfare targeting critical infrastructure. Domestically, a legislative impasse over a crucial $40 billion defense budget underscored internal challenges to Taiwan's defense modernization.

Key Security Developments

• Defense Acquisitions and Arms Deals: U.S. Arms Package Delay
  A significant package of U.S. arms sales to Taiwan, valued at billions of dollars and including air-defense missiles, has been reportedly delayed by the Trump administration. This decision, made to avoid upsetting Chinese President Xi Jinping ahead of a planned April summit, has stalled a package that had already received informal approval from senior U.S. lawmakers in January 2026. The delayed package is crucial for Taiwan's proposed "T-dome" integrated air and missile defense (IAMD) network, which would include systems like Integrated Battle Command Systems (IBCS), Patriot Advanced Capability-3 Missile Segment Enhancement (PAC-3 MSE) systems, National Advanced Surface-to-Air Missile Systems (NASAMS), and Lower Tier Air and Missile Defense Sensors (LTAMDS). This delay introduces uncertainty into Taiwan's immediate defense modernization efforts.

• Defense Policy and Strategic Shifts: Legislative Impasse on Defense Budget
  Taiwan's proposed special military budget of approximately $40 billion (NT$1.25 trillion), intended to enhance defense capabilities over eight years (2026-2033) and focus on asymmetric warfare, faces a significant legislative roadblock. The opposition-held parliament has reportedly blocked the package, citing concerns over fiscal accountability. This internal political contestation has prompted 37 U.S. legislators to send a formal letter to Taiwan's parliamentary leaders, urging them to meet defense spending commitments expected by Washington. The Minister of National Defense, Wellington Koo, has warned that such obstruction could impede military development and weaken deterrence.

• Military Activities and Exercises: Persistent Chinese Incursions and Joint Drills
  Taiwan's Ministry of National Defense (MND) reported continuous Chinese military activities around the island. Between February 22 and February 23, 2026, the MND tracked eight Chinese military aircraft, six naval vessels, and one official ship, with six aircraft crossing the Taiwan Strait median line in Taiwan's central and southwestern air defense identification zone. Additionally, two Chinese balloons were tracked north of Taiwan. These incidents are part of a broader pattern, with Taiwan tracking Chinese military aircraft 190 times and ships 174 times so far in February 2026, indicative of China's escalating "gray zone" tactics.

• Military Activities and Exercises: Multilateral Maritime Cooperative Activities
  From February 23 to February 26, 2026, the militaries of the Philippines, the United States, and Japan conducted joint exercises over the Bashi Channel, which separates the Philippines from Taiwan. This marks the first time such "Multilateral Maritime Cooperative Activities (MMCAs)" have extended beyond the South China Sea, signaling a growing regional commitment to security near Taiwan. China's military reacted angrily to these drills, accusing the Philippines of "co-opting countries outside the region to organise the so-called joint patrols, disrupting peace and stability in the region."

• Maritime and Border Security: Australian Warship Transit
  An Anzac-class frigate of the Royal Australian Navy, HMAS Toowoomba, conducted a routine transit through the Taiwan Strait on February 20-21, 2026. This transit, part of a "Regional Presence Deployment in the Indo-Pacific region," was closely tracked and monitored by the Chinese People's Liberation Army, according to Chinese state-backed media. Such transits by allied nations are viewed by Beijing as challenges to its sovereignty claims over the strait.

• Cybersecurity: Critical Infrastructure Under Threat
  A report from Taiwan's Presidential Office's Whole-of-Society Defense Resilience Committee, released on February 27, 2026, warned of a serious Chinese cyberwarfare threat. The report indicated that China might target Taiwan's critical infrastructure, including energy, water resources, telecommunications, transportation, finance, emergency rescue, hospitals, science parks, and major government agencies, with simultaneous cyberattacks using embedded malware. Chinese cyberattackers have already probed network devices and industrial control systems of energy businesses and attempted to infiltrate telecom networking systems to spy on operations and install malware during software updates.

• Cybersecurity: Grand Hotel Taipei Breach
  On February 23, 2026, the Grand Hotel Taipei confirmed that its information system had been illegally accessed. The hotel stated that an external illegal intrusion was discovered on February 18, and the issue is currently under investigation by the Ministry of Justice Investigation Bureau. This incident highlights the ongoing vulnerability of various sectors to cyberattacks.

• Diplomatic Relations: International Support for Cross-Strait Stability
  Taiwan received diplomatic backing for cross-strait stability from several nations. On February 25, 2026, Canada and South Korea issued a joint statement following a "2+2" ministerial meeting, strongly supporting peace and stability across the Taiwan Strait and opposing "any unilateral actions that seek to alter the status quo." Taiwan's Foreign Minister Lin Chia-lung welcomed this statement. Additionally, on February 25, U.S. Secretary of State Marco Rubio affirmed the importance for Saint Kitts and Nevis to maintain diplomatic ties with Taiwan during a meeting with its Prime Minister Terrance Drew.

• Diplomatic Relations: Cross-Strait Political Engagement
  The CPC-KMT Think Tanks Forum was held in Beijing on February 3, 2026, marking the resumption of a major inter-party exchange platform after a nine-year hiatus. The forum, focused on "Prospects for Cross-Strait Exchanges and Cooperation," aimed to promote cooperation under the "1992 Consensus" and could pave the way for a potential meeting between Chinese President Xi Jinping and Kuomintang leader Chung Liu-wen in March 2026. This engagement signals a different avenue of cross-strait interaction, potentially aimed at containing the Democratic Progressive Party (DPP) administration.

• Diplomatic Relations: Chinese Pressure on Taiwanese Officials
  The Mainland Affairs Council (MAC) on February 27, 2026, criticized the PRC for "oppressing" Taiwan's Minister of the Interior, Liu Shyh-fang. This followed allegations in a Hong Kong-based publication that a relative of Liu's made political donations to her through investments in China. Beijing had previously listed Liu as a "diehard Taiwanese independence separatist" and imposed sanctions on her and her family. The MAC condemned these actions as an attempt to oppress Taiwan's government and people.

Geopolitical Impact and Regional Dynamics

The security developments concerning Taiwan during this period underscore the island's central role in escalating geopolitical tensions in the Indo-Pacific. The U.S.-Taiwan Agreement on Reciprocal Trade (ART), completed on February 12, 2026, represents a deepening of the "triangular fortress" of cooperation encompassing defense, technology, and trade, further integrating Taiwan into the U.S. perimeter of high-tech and supply chain security. However, the reported delay of a significant U.S. arms package to Taiwan, aimed at facilitating an upcoming summit between President Trump and President Xi Jinping, introduces a layer of strategic ambiguity and potential vulnerability. This balancing act by Washington, while seeking to manage relations with Beijing, risks signaling a weaker commitment to Taiwan's defense and could embolden the Chinese Communist Party (CCP) to pursue further concessions.

China's consistent "gray zone" military activities, including daily aircraft and ship incursions across the Taiwan Strait median line and suspected signal spoofing, serve as a constant reminder of Beijing's assertive posture and its intent to normalize military presence around Taiwan. These actions, coupled with explicit warnings about cyberwarfare targeting critical infrastructure, reflect a comprehensive strategy to exert pressure without triggering a full-scale conflict. The joint military exercises conducted by the Philippines, U.S., and Japan in the Bashi Channel, near Taiwan, represent a significant regional counter-response, demonstrating a growing multilateral commitment to maintaining stability and freedom of navigation in critical waterways. China's angry reaction to these drills highlights its sensitivity to perceived external interference in its claimed sphere of influence.

Diplomatically, Taiwan continues to garner support from like-minded nations. The joint statement from Canada and South Korea affirming cross-strait stability and opposing unilateral changes to the status quo, along with U.S. affirmation of diplomatic ties with Saint Kitts and Nevis, indicates a concerted international effort to uphold the existing order. However, China's efforts to engage Taiwan's opposition Kuomintang (KMT) through the CPC-KMT Think Tanks Forum, focusing on economic cooperation under the "1992 Consensus," reveal Beijing's strategy to leverage internal Taiwanese political divisions to advance its reunification agenda. This dual approach of military coercion and political engagement aims to isolate the ruling Democratic Progressive Party (DPP) and shape Taiwan's future in line with Beijing's objectives.

Military and Defense Analysis

Taiwan's military and defense posture during this period is characterized by a strong resolve for self-defense amidst significant challenges. President Lai Ching-te's administration has emphasized an asymmetric defense strategy, prioritizing agility over scale, with a focus on enhanced missile systems, coastal defense mechanisms, expanded naval patrol capacity, and air force modernization programs. This includes plans to procure advanced systems such as HIMARS multiple rocket launchers, with 18 remaining systems expected by the end of 2026, and a further 82 HIMARS systems planned for acquisition. Additionally, Taiwan is slated to receive 28 M1A2 Abrams tanks, anti-tank mine layer systems, reconnaissance drones, and modernized assault rifles in 2026, addressing a backlog of over $20 billion in U.S. arms purchases.

However, the effectiveness of these modernization efforts is directly impacted by the ongoing legislative impasse over President Lai's proposed $40 billion special defense budget (NT$1.25 trillion). The opposition-controlled parliament's resistance to this budget, despite pressure from U.S. legislators, threatens to slow down critical procurement and development programs. This internal political friction creates a window of vulnerability, as Taiwan seeks to rapidly build its deterrence capabilities against a rapidly modernizing People's Liberation Army (PLA). The PLA's continuous "gray zone" tactics, including daily air and naval incursions and sophisticated signal spoofing, are designed to test Taiwan's response capabilities, exhaust its forces, and normalize a heightened military presence around the island. The delay in the U.S. arms package, particularly those related to the "T-dome" integrated air and missile defense network, further complicates Taiwan's ability to establish a robust, multi-layered defense against aerial threats.

Outlook and Forecast

Short-term trends (1-3 months): In the immediate future, Taiwan can expect a continuation, and potentially an intensification, of Chinese "gray zone" military activities, including air and naval incursions, as Beijing seeks to test the new U.S.-Taiwan "triangular fortress" and gauge the resolve of the Lai administration. Cyberattacks targeting Taiwan's critical infrastructure are highly likely to persist, with a particular focus on energy and telecommunications sectors, as China aims to gather intelligence and pre-position capabilities for potential future conflicts. Diplomatically, the outcome of the anticipated Trump-Xi summit in April 2026 will be a critical determinant of U.S. arms sales to Taiwan and the broader cross-strait dynamic. Taiwan will continue to seek and receive statements of support for cross-strait stability from international partners, but these may not always translate into immediate, tangible security enhancements. The legislative impasse over Taiwan's defense budget is likely to remain a significant domestic challenge, potentially delaying crucial modernization programs.

Critical flashpoints and risk areas: The primary flashpoint remains the Taiwan Strait, with the potential for miscalculation during increased military activities by both sides. The delay in U.S. arms deliveries could create a perceived gap in Taiwan's defense capabilities, potentially tempting Beijing to increase pressure. The legislative deadlock on the defense budget poses a significant internal risk, undermining Taiwan's ability to fund and implement its asymmetric defense strategy effectively. The sophistication and frequency of Chinese cyberattacks on critical infrastructure represent a constant, evolving threat that could disrupt essential services and sow societal discord. Any perceived shift in U.S. "strategic ambiguity" or a weakening of its commitment to Taiwan, particularly following the Trump-Xi summit, could significantly alter Beijing's strategic calculus.

Indicators to monitor: Key indicators to monitor include the resolution of Taiwan's defense budget impasse and the progress of its implementation. The status and delivery schedule of delayed U.S. arms packages will be crucial. The frequency, scale, and nature of PLA air and naval incursions, especially any deviations from established "gray zone" tactics, should be closely watched. The outcomes and rhetoric surrounding the Trump-Xi summit will provide insights into U.S.-China-Taiwan relations. Furthermore, the effectiveness of Taiwan's cybersecurity defenses against ongoing Chinese attacks and any new reported breaches will be vital. Finally, the level of international diplomatic and military cooperation with Taiwan, particularly joint exercises and statements from key allies, will signal the broader regional commitment to Taiwan's security.

Strategic recommendations: Taiwan should prioritize building domestic consensus on its defense strategy and budget to overcome legislative hurdles and ensure timely implementation of modernization programs. It must continue to invest heavily in asymmetric defense capabilities, focusing on mobile, survivable, and precision strike systems that can deter a larger adversary. Enhancing cyber resilience across all critical infrastructure sectors, including regular drills and international cooperation on threat intelligence, is paramount. Diplomatically, Taiwan should diversify its international partnerships beyond traditional allies, leveraging economic and technological strengths to garner broader support for its security and international participation. Finally, Taiwan should maintain a calibrated response to Chinese provocations, avoiding escalation while clearly demonstrating its resolve and defensive capabilities.
