U.S. Legislative Initiatives to Bolster Taiwan’s Defense and Tech Resilience
Four critical Taiwan-related bills were recently introduced or advanced in the U.S. Congress: the Blue Skies for Taiwan Act and the First Island Chain Deterrence Act were both introduced in the Senate on March 26, 2026; the Chip Security Act was unanimously advanced by the House Foreign Affairs Committee (HFAC) also on March 26; and the Critical Undersea Infrastructure Resilience Initiative Act was introduced in the House on April 2.
Why They Matter
- Blue Skies for Taiwan Act (S.4259): Introduced by Senators Jeff Merkley (D-OR), Ted Cruz (R-TX), Andy Kim (D-NJ), and John Curtis (R-UT), this bill promotes the development of secure, resilient unmanned aerial systems (UAS). The bipartisan effort will identify strategic roadblocks and expand opportunities for the U.S. and Taiwan to create PRC-independent drone systems and components to bolster both Taiwan’s defense and U.S. national security.
- First Island Chain Deterrence Act (S.4223): Sponsored by Senators Michael Bennet (D-CO) and Pete Ricketts (R-NE), this legislation tackles the critical backlog in U.S. arms deliveries to Taiwan, Japan, and the Philippines. It directs the Government Accountability Office (GAO) to investigate bureaucratic bottlenecks that hinder the “strong denial defense” strategy outlined in the 2026 National Defense Strategy, ensuring that Taiwan and other regional partners receive purchased weapons without further delay.
- Chip Security Act (H.R.3447): Introduced by Rep. Bill Huizenga (R-MI) in May 2025 and advanced by HFAC in late March 2026, this act aims to prevent the illicit diversion of advanced AI chips to foreign adversaries, specifically the PRC. The bill requires advanced chip manufacturers to adopt technical security safeguards, including location-verification mechanisms, to prevent smuggling to unauthorized end users. This act ensures U.S. and allied innovations do not power the Chinese military’s AI-driven capabilities.
- Critical Undersea Infrastructure Resilience Initiative Act (H.R.8177): Introduced by Representatives Mike Lawler (R-NY), Dave Min (D-CA), and Greg Stanton (D-AZ), this act addresses the PRC’s “gray zone” sabotage of Taiwan’s undersea cables. It mandates real-time monitoring systems, establishes a Cross-Strait Contingency Planning Group, and authorizes targeted sanctions against those complicit in sabotaging critical undersea systems affecting Taiwan and U.S. allies.
Implications
Collectively, these legislative measures bolster U.S.-Taiwan defense integration by institutionalizing cooperation on PRC-independent drone production, accelerating arms deliveries to First Island Chain partners, tightening safeguards against the diversion of advanced AI chips to the PRC, and hardening the protection of Taiwan’s critical undersea infrastructure.
These bills underscore the growing bipartisan focus on Taiwan’s pivotal role in regional security. They enhance Taiwan’s capacity to operate seamlessly alongside U.S. and allied defense systems, thereby strengthening credible and robust regional deterrence against PRC aggression.

U.S. Congressional Delegation to Taiwan Urges Passage of US$40 Billion Special Defense Budget
On March 30, 2026, Senators Jeanne Shaheen (D-NH), John Curtis (R-UT), Thom Tillis (R-NC), and Jacky Rosen (D-NV) arrived in Taiwan to reaffirm ironclad Congressional support for the U.S.-Taiwan security and defense partnership. The bipartisan senators met with President Lai Ching-te, Vice President Hsiao Bi-khim, Foreign Minister Lin Chia-lung, National Security Council Secretary-General Joseph Wu, and other senior Taiwanese officials.
The Congressional Delegation (CODEL) reaffirmed the U.S. Congress’s commitment to support Taiwan and strengthen Taiwan’s self-defense. Members of the delegation publicly backed President Lai’s proposed NT$1.25 trillion (approximately US$40 billion) special defense budget, urging the Legislative Yuan to pass the measure without delay to address critical gaps in defense capabilities.
The delegation also emphasized Taiwan’s pivotal role in global prosperity and high-tech supply chain. Senator Curtis, who co-led the delegation, warned that “an attempted attack on Taiwan could trigger a $10 trillion global economic shock, immediately contracting the U.S. GDP by roughly 10 percent.”
Why It Matters
With President Trump’s reported upcoming visit to China scheduled for May 2026, this recent CODEL signals to the world that supporting Taiwan remains a central, bipartisan priority of U.S. foreign policy. “I don’t think that there’s ambiguity at all from the United States in terms of support of Taiwan,” Senator Tillis underscored. This signaling is critical as Washington continues to monitor Taiwan’s operational readiness and the domestic political consensus required to sustain long-term defense investments.
Global Taiwan Institute (GTI) Director John Dotson assesses that President Lai’s supplementary special defense budget addresses long-standing concerns regarding Taiwan’s “asymmetric” deterrence. The proposal raises Taiwan’s defense spending up to around 3.3 percent of its GDP for 2026 and focuses heavily on purchasing advanced U.S. arms, such as M142 HIMARS and ALTIUS unmanned aerial systems. It also includes several categories that point to closer U.S.-Taiwan defense cooperation and expanded joint development.
Implications
The recent CODEL underscores Congress’s commitment to a “peace through strength” strategy, which emphasizes that the U.S. and Taiwan must work together to deter Chinese aggression.
Taiwan, for its part, has been actively working with the U.S. to evolve beyond its traditional role as a mere purchaser and transition into a strategic co-developer and co-producer of its own advanced defensive weapons. This includes the recent successful undersea trial for its first indigenous submarine and the expansion of a “non-red” democratic supply chain for uncrewed aerial vehicles (UAVs) or drones.
