For Taiwan, the prospect of a Chinese blockade isn’t only about ships and missiles. It’s also about factories, supply lines, and whether the island can keep critical industries running if key imports are cut off. As Beijing deepens its influence over global technology supply chains, Taiwanese officials and businesses are increasingly treating “industrial resilience” as a core part of national security—and they’re preparing for a scenario where access to essential materials and components could be interrupted with little warning.
That urgency is helping drive a major new push toward defense autonomy, backed by a reported NT$400 billion effort aimed at strengthening Taiwan’s ability to build, maintain, and sustain its own defense capabilities. The goal is not simply to buy more equipment, but to reduce dependence on external suppliers and make Taiwan’s defense ecosystem harder to disrupt under pressure.
A blockade scenario would test more than Taiwan’s armed forces. It could strain everything from replacement parts and specialized electronics to the steady flow of materials required for manufacturing. Modern defense systems rely on complex, globally distributed production networks—networks that can be vulnerable to geopolitical interference. Taiwan’s strategy reflects a growing recognition that self-reliance is as much about securing industrial inputs as it is about fielding advanced platforms.
The NT$400 billion initiative signals a broader shift: building layered resilience across procurement, production, stockpiling, and domestic manufacturing capacity. In practical terms, that can include expanding local development of key components, diversifying suppliers where possible, and ensuring that critical systems can be repaired and sustained at home even if international logistics slow down or stop.
This move also aligns with Taiwan’s wider challenge of operating in a world where economic leverage and supply chain control can be used as strategic tools. As technology supply chains become increasingly politicized, Taiwan’s push for defense autonomy aims to reduce exposure to choke points—especially those that could be exploited during a crisis.
Ultimately, Taiwan’s message is straightforward: deterrence isn’t only about front-line capability. It’s also about endurance. By investing heavily in defense autonomy and industrial readiness, Taiwan is working to ensure it can keep its systems functioning, its production lines operating, and its security posture intact—even under the pressure of a potential blockade.
