Arizona Governor Katie Hobbs’s high-profile visit to Taiwan (March 16-19, 2025) comes in the wake of TSMC chairman C.C. Wei’s recent announcement of a substantial increase in US investment to US$100 billion. This expanded commitment has intensified debates within Taiwan about technology transfer and potential industrial hollowing effects on the island’s semiconductor ecosystem. The timing of the investment expansion coincides with growing efforts by US states to attract critical segments of the semiconductor supply chain.
