The Trump administration reduced tariffs on Taiwanese imports to 10%.
The previous tariff rate was 15%.
The move occurred one week after Taiwan Semiconductor Manufacturing Company (TSMC) announced its Arizona expansion.
TSMC committed an additional $100 billion to its U.S. operations.
The company's total U.S. investment now reaches approximately $265 billion.
An Arizona State University professor linked the tariff reduction to TSMC's capital commitment.
The expansion targets rising demand for advanced AI chips and a stronger American semiconductor supply chain.
