It would be “impossible” to move 40% of Taiwan’s semiconductor capacity to the U.S., the island’s top tariff negotiator said, pushing back against recent comments by American officials who called for a major production shift.
In an interview with Taiwanese television channel CTS that was broadcast late on Sunday, Taiwan Vice Premier Cheng Li-chiun said she had made it clear to Washington that Taiwan’s semiconductor ecosystem, built up over decades, could not be relocated.
“I have made it very clear to the United States that this is impossible,” she said, referring to the 40% goal the U.S. has floated.
That ecosystem will continue to grow in Taiwan, Cheng said, adding that the semiconductor industry would keep investing at home.


Those investments should definitely come with strings attached. But there’s a lot you need to invest into.
You’ll need to keep (some amount of) the money flowing at least until the industry can be independently competitive on the world stage. Mishandling your burgeoning industry can mean that all that investment money and a large number of jobs suddenly go up in smoke.
Note: All of this assumes that you’ll buy your manufacturing equipment from established, potentially foreign companies like ASML and Zeiss. If you want to make that stuff domestically as well you can probably add another hundred billion bucks and a decade or two of very dedicated catch-up to the bill.
