President Donald Trump announced tariffs on $200 billion worth of Chinese imports Monday, prompting Beijing to impose retaliatory taxes on $60 billion worth of American imports. The two countries had already placed tariffs on $50 billion worth of each other’s products. 

The move was part of a broader effort by the Trump administration, which has also imposed duties on Canada, Mexico, and the European Union, to reform trade practices perceived as unfair. In a statement, Trump asserted tariffs will ultimately help protect Americans from Chinese actions that “plainly constitute a grave threat to the long-term health and prosperity of the United States economy.”

But many economists and public officials warn import taxes will cause financial strain for American companies and consumers, pushing up costs and reducing access to foreign markets. The US Chamber of Commerce, a private lobbying group, said in a report that 14 states could suffer “extremely significant damage” after the latest round of tariffs. Here are their results, drawn from US Department of Commerce data.
