President Donald Trump on Tuesday said he told the Taiwan Semiconductor Manufacturing Company, which has pledged to build new factories in the United States, it would pay a tax of up to 100% if it did not build its plants in the country.

President Donald Trump claimed his threat of steep import tariffs pushed TSMC to boost its U.S. investment from $65 billion to $200 billion without government aid.

As the economy reels from President Trump’s punishing import taxes on China—now reaching a staggering 104 percent—sectors of the tech industry are bracing for even more pain. Trump threatened TSMC, the world’s most prolific silicon chip manufacturer, with company-specific tariffs if they didn’t accede to his demands.
