President Donald Trump imposed stiff tariffs on imported solar panels and washing machines Monday, aiming to protect U.S. manufacturers.
The U.S. Trade Representative's office made the recommendation to the president for the tariffs.
It said the independent U.S. International Trade Commission found that such imports were a "substantial cause of serious injury to domestic manufacturers."
"The president's actions make clear again that the Trump administration will always defend American workers, farmers, ranchers and businesses," U.S. Trade Representative Robert Lighthizer said Monday.
Trump has often promised to get tough with China and other exporters that he says compete unfairly with U.S. manufacturers.
The tariffs start out at 30 percent on solar panels and decline over time.
