The Taiwanese chip giant TSMC’s plan to invest $100 billion in the United States has been met with anxiety and criticism in its home country.

"TSMC's decision is necessary for its future development. The government did not face pressure from the United States," Taiwan President Lai Ching-te said.

Touting the $100 billion expansion Taiwan Semiconductor Manufacturing Co. announced on Monday, President Donald Trump boasted that he’d lured the chipmaker not with subsidies

The generally law-abiding TSMC did not even submit the investment plan to Taiwan’s Ministry of Economic Affairs for assessment and approval, as it had previously done. In other words, the announcement was made unilaterally by the Trump administration.

Taiwanese chipmaker TSMC is expanding investment in the United States because of large U.S. customer demand, its CEO said on Thursday, adding that its production lines there are already fully booked for this year and the next two years.

TAIPEI, Taiwan — Taiwan’s president and top chipmaker TSMC held a joint news conference Thursday to defend the company’s decision to invest $100 billion in the U.S., saying it stemmed from customer demand and not pressure from the Trump administration.

The world’s largest contract chip maker’s latest $100 billion investment plan is aimed at meeting strong demand from U.S. customers, Wei said.
