Following the announcement of another $100 billion investment from Taiwanese chipmaker TSMC, Trump took questions from the media and confirmed that the tariffs announced last month will go into effect Tuesday.

The stock market reacted with the S&P 500 index dipping 2%. Fears over inflation and economic uncertainty add to an already tense relationship with the United States’ neighboring nations.
