Taiwan Security Report — February 27, 2026

Security analysis based on open-source intelligence and web research. Period: February 20 — February 27, 2026.

Executive Summary

During the period of February 20-27, 2026, Taiwan faced persistent and evolving security challenges primarily stemming from increased Chinese military pressure and "grey-zone" tactics. The People's Liberation Army (PLA) maintained a near-daily presence of aircraft and vessels around Taiwan, with notable incidents including drone flights broadcasting false transponder signals, interpreted as potential invasion rehearsals. Concurrently, Taiwan solidified its defense posture by planning a significant increase in its 2026 defense budget to over 3% of GDP, despite internal legislative hurdles. Diplomatic and trade relations with the United States saw the signing of a new Agreement on Reciprocal Trade, though a major US arms sale remained in limbo due to US-China high-level talks. Cybersecurity remained a key focus, with major conferences held to bolster national resilience against evolving threats.

Key Security Developments

• Military Activities and Exercises
  Taiwan's Ministry of National Defense (MND) reported frequent incursions by People's Liberation Army (PLA) aircraft and People's Liberation Army Navy (PLAN) vessels throughout the week. On February 27, 2026, 8 PLA aircraft and 6 PLAN vessels were detected, with 6 aircraft crossing the median line and entering Taiwan's central and southwestern Air Defense Identification Zone (ADIZ). Earlier in the week, on February 25, 28 sorties of Chinese aircraft were detected, with 22 crossing the median line, and on February 21, 8 aircraft and 7 vessels were observed. These persistent activities underscore China's ongoing pressure campaign and efforts to normalize military presence near Taiwan.

• Chinese Drone Masking in Suspected Taiwan Rehearsal
  A significant development involved a large Chinese military drone, identified by the call sign YILO4200 (linked to the Wing Loong 2 UAV), conducting at least 23 flights since August over the South China Sea while broadcasting false transponder signals. These flights, detected as recently as February 26, 2026, used registration codes belonging to unrelated aircraft, including a Belarusian cargo jet and a British Royal Air Force fighter. Security analysts interpret this tactic as a sophisticated "grey-zone" operation and a potential rehearsal for future conflict scenarios involving Taiwan, aiming to test electronic warfare and deception capabilities. The flight paths, when overlaid on a map of Taiwan, align with key military and political sites, including areas near Taipei and along the island's southern coastline.

• Defense Policy and Strategic Shifts: Increased Defense Spending
  Taiwan plans to significantly boost its defense spending in 2026, with the budget expected to exceed 3% of its Gross Domestic Product (GDP), reaching T$949.5 billion (approximately US$40 billion). This represents a 22.9% increase over 2025 and marks the first time since 2009 that defense spending will cross the 3% threshold. The increase is driven by the rising threat from China and aims to invest billions more in new equipment, including domestically built submarines, and to convince the United States of Taiwan's commitment to self-defense.

• Legislative Impasse over Defense Budget
  Despite the planned increase, Taiwan's special defense budget faced legislative hurdles. The Legislative Yuan, controlled by the opposition Chinese Nationalist Party (KMT) and Taiwan People's Party (TPP), reportedly blocked a critical increase in the defense budget, instead advancing a slimmed-down alternative. This opposition has stalled a US$40 billion defense package intended for critical capabilities, including advanced US weapons platforms and a "T-Dome" multi-layered air and missile defense system. This internal political dynamic risks undermining Taiwan's security and potentially damaging Taiwan-US relations.

• Diplomatic Relations: US-Taiwan Agreement on Reciprocal Trade (ART)
  On February 12, 2026, the United States and Taiwan signed the Agreement on Reciprocal Trade (ART) in Washington, D.C.. This significant trade deal aims to reduce or eliminate up to 99% of tariff and non-tariff barriers on American imports in Taiwan, including politically sensitive agricultural products. In return, the US will apply a 15% reciprocal tariff on certain Taiwanese goods, down from 20% previously. The ART also includes Taiwan's commitment to $250 billion in US investments, primarily in semiconductor manufacturing, and mandates regulatory alignment on intellectual property and digital trade.

• Diplomatic Relations: Taiwan Seeks US Assurances on Trade Deal
  Following a US Supreme Court ruling on February 20, 2026, that the International Emergency Economic Powers Act (IEEPA) does not authorize the President to impose tariffs, Taiwan sought assurances from the United States that the terms of the recently negotiated ART would not be altered. The White House subsequently reimposed a 10% global tariff under Section 122 of the Trade Act of 1974, raising concerns in Taiwan about the stability of its preferential treatment under Section 232 for semiconductors.

• Defense Acquisitions and Arms Deals: US Arms Sale in Limbo
  A planned US$11 billion arms sale package to Taiwan, announced in December 2025, faced uncertainty during this period. The Trump administration was reportedly discussing whether to delay the sale to preserve a high-stakes meeting between President Trump and Chinese President Xi Jinping in Beijing in April. China has vehemently opposed such sales, viewing them as interference in its sovereign territory. The package was expected to include Patriot anti-missile interceptors and other weapons crucial for Taiwan's "T-dome" integrated air and missile defense (IAMD) network.

• Cybersecurity: Major Conferences Held
  Taiwan hosted significant cybersecurity events during the week. The International Conference on Cybersecurity and Cloud Computing (ICCCC) took place in Taipei City on February 26, 2026. Additionally, CYBERSEC 2026, Taiwan's leading cybersecurity conference, was centered around the theme "RESILIENT FUTURE," bringing together global cybersecurity leaders and showcasing over 400 international cybersecurity brands. These events highlight Taiwan's proactive approach to strengthening its cyber resilience against constant and evolving cyber threats.

• Maritime and Border Security: Signal Spoofing
  The PRC may be employing signal spoofing to create illusory PRC vessels, including a China Coast Guard (CCG) ship, inside a Taiwanese harbor. This tactic, observed from at least May 2023 through February 2026 at the mouth of the Tamsui River in New Taipei, is suspected to be part of a cognitive warfare effort to degrade Taiwan's threat awareness.

• Intelligence Activities: Chinese Military Purges
  In January 2026, Chinese generals Zhang Youxia and Liu Zhenli were dismissed in a significant purge within China's Central Military Commission (CMC). While occurring just before the reporting period, this event's implications were discussed, with analysts suggesting that the turmoil in China's military high command makes a complex military operation like an invasion of Taiwan less likely in the short to near term. However, it is also seen as potentially increasing the risk over the medium term as new leadership is brought in to accelerate training and readiness.

Geopolitical Impact and Regional Dynamics

The security developments in Taiwan during this period underscore the escalating strategic flashpoint that China-Taiwan relations represent in 2026. The persistent military pressure from Beijing, manifested through daily air and naval incursions and sophisticated "grey-zone" tactics like drone masking, directly challenges regional stability. These actions are interpreted as signaling China's readiness to project force and test response thresholds, increasing the risk of miscalculation in the Taiwan Strait. The international community, particularly the US and its allies, views these developments with concern, as evidenced by the US National Defense Strategy (NDS) 2026 continuing to prioritize the China threat and Taiwan's defense.

Relations with major powers, especially the United States and China, remain highly complex and intertwined. The signing of the US-Taiwan Agreement on Reciprocal Trade (ART) on February 12, 2026, signifies a deepening of economic ties and a strategic effort by Taiwan to make itself indispensable to the US economy, particularly in the semiconductor sector. This "triangular fortress" of defense, technology, and trade aims to bolster Taiwan's security by strengthening its economic leverage with Washington. However, this positive development for Taiwan is shadowed by the US's reported hesitation to proceed with a major arms sale, a decision influenced by President Trump's upcoming summit with President Xi Jinping. This delicate balancing act by the US highlights the constant tension between supporting Taiwan's defense and managing the broader US-China relationship, which Beijing consistently attempts to leverage against Taiwan's international standing.

The broader strategic landscape is also affected by these dynamics. Japan has already protested China's move to restrict the export of "dual-use" items to Japanese entities, and Japanese Prime Minister Sanae Takaichi previously stated that a Chinese attack on Taiwan would constitute a "survival-threatening situation" for Japan. The US-Philippines Bilateral Strategic Dialogue on February 16, 2026, reaffirmed commitments to their Mutual Defense Treaty, extending to the South China Sea, which indirectly strengthens regional deterrence against Chinese aggression that could impact Taiwan. Furthermore, while Lithuania expressed interest in restoring normal diplomatic relations with China, it also sought to increase cooperation with Taiwan, indicating a nuanced approach by some European nations. The ongoing purges within the PLA's high command, while potentially reducing short-term invasion risk, also suggest a longer-term intent by Xi Jinping to enhance the PLA's capability for a Taiwan contingency by 2027.

Military and Defense Analysis

Taiwan's military and defense posture during this period reflects a clear commitment to modernization and enhanced deterrence in the face of persistent threats from China. President Lai Ching-te's pledge to boost defense efforts and the planned increase in the 2026 defense budget to over 3% of GDP are central to this strategy. This significant financial commitment, reaching T$949.5 billion (approximately US$40 billion), aims to invest in new equipment and capabilities, including domestically built submarines. The inclusion of the Coast Guard in the defense budget for the first time highlights a recognition of China's "grey-zone" tactics, which often involve coast guard patrols near Taiwan's islands.

However, the effectiveness of these modernization programs is currently facing challenges. The legislative impasse over a special defense budget of US$40 billion, with the opposition-controlled Legislative Yuan blocking the package, poses a significant hurdle. This stalled funding is critical for acquiring advanced US weapons platforms and developing Taiwan's "T-Dome" integrated air and missile defense (IAMD) network, which would integrate existing Patriot and Tien Kung missile battalions with advanced sensors and command-and-control infrastructure. The delay in these acquisitions could exacerbate existing shortfalls in military intelligence, surveillance, and reconnaissance capabilities, hindering Taiwan's ability to respond to evolving threats.

The uncertainty surrounding the US$11 billion arms sale package from the United States further complicates Taiwan's capability development. While the US has previously notified Taiwan of a US$330 million arms sale in November 2025, the larger package, including Patriot anti-missile interceptors, is reportedly being delayed due to US-China diplomatic considerations. This situation underscores Taiwan's reliance on external support for advanced defense systems and the geopolitical complexities that can impact its acquisition timelines. Despite these challenges, Taiwan's military continues to conduct annual drills, such as the spring military drills focusing on air defense, to prepare for potential conflict.

Outlook and Forecast

Short-term trends (1-3 months): In the immediate future, Taiwan is likely to experience continued heightened military pressure from China. The daily incursions by PLA aircraft and vessels, along with sophisticated "grey-zone" tactics like drone masking, are expected to persist as Beijing seeks to normalize its presence and test Taiwan's response capabilities. The US-China diplomatic engagement, particularly President Trump's upcoming summit with President Xi Jinping in April, will be a critical factor influencing the pace and nature of US arms sales to Taiwan. A delay or reduction in the anticipated US$11 billion arms package could create a temporary capability gap for Taiwan and signal a cautious approach from Washington. Internally, the legislative impasse over Taiwan's defense budget will likely continue, potentially slowing down critical modernization programs and domestic defense acquisitions. Taiwan will also continue to strengthen its cybersecurity defenses, with the momentum from recent conferences and initiatives expected to translate into practical measures.

Critical flashpoints and risk areas: The most critical flashpoint remains the Taiwan Strait, with the risk of miscalculation or escalation due to continuous PLA activities. China's increasingly sophisticated "grey-zone" tactics, such as signal spoofing and masked drone flights, could lead to confusion and unintended confrontations. The US arms sales represent another significant risk area; any perceived wavering in US commitment could embolden Beijing and undermine Taiwan's deterrence. Furthermore, the internal political divisions over defense spending could weaken Taiwan's overall preparedness and send mixed signals to both allies and adversaries. The Bashi Channel, a strategic chokepoint for China's navy, will remain an area of interest for monitoring Chinese military movements.

Indicators to monitor: Key indicators to monitor include the frequency and intensity of PLA air and naval incursions around Taiwan, particularly any changes in their patterns or the types of assets deployed. The outcome of the US-China summit in April and subsequent decisions regarding US arms sales to Taiwan will be crucial. Progress on Taiwan's domestic defense budget in the Legislative Yuan, especially regarding funding for the "T-Dome" system and other modernization initiatives, should be closely watched. Any new developments in China's electronic warfare and deception capabilities, particularly regarding drone operations and signal spoofing, will be important to track. Finally, the rhetoric and actions of Lithuania and other European nations regarding their diplomatic and economic engagement with both China and Taiwan will offer insights into broader international support for Taiwan.

Strategic recommendations: Taiwan should prioritize resolving the legislative impasse on its defense budget to ensure timely acquisition of critical defense capabilities and maintain credibility with international partners. It is essential to continue investing in asymmetric warfare capabilities and indigenous defense production, such as submarines, to enhance self-reliance. Taiwan should also bolster its cybersecurity infrastructure and resilience through continued collaboration and innovation, as demonstrated by recent conferences. Diplomatically, Taiwan should continue to strengthen its economic and trade ties with like-minded countries, leveraging agreements like the ART with the US to build a "triangular fortress" of support. Finally, Taiwan needs to maintain robust intelligence, surveillance, and reconnaissance (ISR) capabilities to effectively monitor and counter China's evolving "grey-zone" tactics and potential deception operations.
