This news was announced by Trump during a press conference with Apple CEO Tim Cook in the Oval Office that afternoon. At the meeting, Cook announced simultaneously that Apple plans to invest an additional $100 billion in research and manufacturing in the United States over the next four years, in addition to the previously promised $500 billion. Trump further clarified at the press conference: "We will impose extremely high tariffs on chips and semiconductors, but for companies like Apple, the good news is that as long as they choose to build factories in the United States or promise to build factories in the United States, there will be no costs." He emphasized again, "That is to say, tariffs on chips and semiconductors are about 100%, but companies that build factories in the United States can be exempted." Previously, Trump mentioned that tariffs on chips and semiconductors could be introduced as early as next week. As key components in almost all industries, if tariffs are imposed on chips and semiconductors, it may push up the prices of various products such as smartphones, laptops, and home electronics. In fact, apart from Apple, several top chip manufacturers have promised to produce some products in the United States. According to the Semiconductor Industry Association, since 2020, the United States has announced over 130 related investment projects with a total amount of $600 billion. Specifically, TSMC has pledged to invest $165 billion in the US manufacturing industry; Nvidia announced in April this year that it plans to invest $500 billion in artificial intelligence infrastructure in the United States over the next four years; GlobalFoundries pledged in June this year to invest $16 billion to expand its semiconductor manufacturing facilities in New York and Vermont; In the same month, Texas Instruments also announced a $60 billion investment to add seven chip manufacturing plants in the United States. Trump also pointed out that if companies promise to build factories in the United States but fail to fulfill their commitments, they will once again face tariffs and countermeasures.
