Beyond the Silicon Shield: Taiwanese official says Taiwan seeks to become a “Trust Shield” in the global AI economy

In the latest episode of Taiwan Frontlines, produced by Taiwan Current News (TCN) in partnership with the German Marshall Fund of the United States (GMF), Isabel Hou (侯宜秀), the deputy minister at Taiwan’s Ministry of Digital Affairs (MODA), discusses how Taiwan can move beyond the traditional concept of the “Silicon Shield” and reposition itself as a global “Trust Shield” in the age of AI.

She also explains why the current geopolitical and technological landscape may offer Taiwanese companies an especially favorable window to expand overseas. Hou elaborates on Taiwan’s role in Pax Silica, the US-led initiative aimed at building resilient and trustworthy AI supply chains.

From protection to partnership

For a long time, Taiwan’s semiconductor dominance has been encapsulated by the idea of a “Silicon Shield” — the proposition that the island’s indispensable role in the global technology supply chain gives it strategic leverage and raises the costs of any military conflict.

However, MODA Deputy Minister Hou argued that the concept may no longer fully capture Taiwan’s position in an increasingly interconnected AI economy and its global supply chain.

Hou added that she would be cautious about framing Taiwan’s semiconductor strength simply as a shield protecting Taiwan itself. The more important question, she said, is where Taiwan sits within the broader global AI supply chain.

Hou described Taiwan as a “keystone” in the global AI supply chain.

Her argument is that the semiconductor industry’s strategic value does not stop at chips. Taiwan’s capabilities extend from components and servers to AI and computing infrastructure, creating opportunities for Taiwanese investments overseas and cooperation with partners far beyond the island.

Turning the Silicon Shield into a Trust Shield

That shift, Hou said, also changes how Taiwan views the overseas expansion of its companies.

Rather than treating investment in the United States, Europe and other markets as a dilution of Taiwan’s technological advantage, Hou said the current environment is in fact favorable for Taiwanese companies to internationalize.

She argued that Taiwan now has an opportunity to work with trusted partners to build what she describes as a trustworthy AI system — encompassing not only hardware, but the wider infrastructure and services required to operate AI at scale.

The evolution she envisions is therefore from a “Silicon Shield” to a “Trust Shield.”

Taiwan’s strategic value, in this formulation, would derive not merely from the fact that critical chips are manufactured on the island, but from its ability to become an indispensable and trusted partner across multiple layers of the global AI ecosystem.

The US-led Pax Silica

That vision intersects directly with Pax Silica, a US-led initiative launched by the US State Department in December 2025.

The initiative seeks to strengthen secure and resilient supply chains for technologies critical to AI, spanning critical minerals, rare earth elements, energy inputs, advanced manufacturing, semiconductors, AI infrastructure and logistics.

Pax Silica is framed as a positive-sum partnership designed to reduce what it calls “coercive dependencies” and to strengthen resilience across the AI technology supply chain — from the extraction and processing of critical minerals to semiconductor manufacturing and computing infrastructure.

The initiative has since expanded. At its second summit in Washington in June 2026, the United States said Pax Silica had grown to 24 declaration signatories, while 35 economies endorsed a separate Joint Statement on AI Opportunity. On July 31, Italy became the 25^th signatory.

The second summit also introduced new initiatives, including PaxPass, a platform designed to streamline the trusted movement of critical AI-related goods, according to the US State Department.

At the same summit, the US State Department also unveiled a new initiative called Foundry School, a workforce-development program developed in partnership with Stanford University to strengthen advanced-manufacturing skills across participating economies.

Taiwan’s place in the initiative

Taiwan is not a signatory to the Pax Silica Declaration, but it has endorsed the declaration’s principles through a January 2026 joint statement with the United States and has participated in the initiative’s discussions as a key partner in the global AI supply chain.

Hou participated in the inaugural summit in December 2025 as a guest speaker and later represented Taiwan at the second summit. She described Taiwan as an “essential partner,” particularly because of its semiconductor and ICT expertise which is critical to the AI economy.

Hou said that for Taiwan, the value of Pax Silica is therefore reciprocal: Taiwan can contribute industrial knowledge, know-how, and technological capabilities, while its companies gain opportunities to deepen relationships with partners across trusted supply chains.
