Amid concerns from U.S. businesses that President Trump’s trade agenda will hinder a bustling economy, the administration is moving forward with its plan to impose tariffs on an estimated $34 billion worth of Chinese imports.

The levies set to take effect on Friday will hit products from nuclear reactor parts to electromagnets. The U.S. trade representative is considering 25 percent duties on an additional $16 billion in products, and Trump has threatened to increase the overall amount to as much as $500 billion. China has already pledged to respond with its own dollar-for-dollar tariffs.
