Trump announced plans to impose 10% tariffs on Chinese goods “above any additional tariffs,” after blaming the country for the inflow of illegal fentanyl into the U.S.

While China could offset American tariffs by letting its currency fall, that might endanger Beijing’s recent efforts to stabilize the economy.

If enacted, they would violate the 2020 deal that the United States inked with Canada and Mexico during Donald Trump’s first term.
