U.S. Officials Warn of Risks from Silicon Valley’s Dependence on Taiwan Chips

U.S. officials have long warned Silicon Valley about its heavy reliance on Taiwan, which produces about 90% of the world's high-end computer chips. Despite efforts by Presidents Biden and Trump—including financial incentives and tariffs—to encourage domestic chip production, major tech companies have largely maintained dependence on Taiwan. Concerns have grown amid Chinese military drills near Taiwan, with officials warning that a blockade could severely disrupt global tech supply chains and the broader economy.
