The Japanese government is set to impose protective duties on beef imports from the United States due to the likelihood of exceeding the mutually agreed quota. The proposed duties would increase from 25.8% to 38.5%. This is the first time such measures will be introduced since 2017 and could potentially damage the improving economic relations with the Biden administration. The decision comes as tensions persist over the import of American meat, a situation worsened by past disputes under the Trump administration.
