China is no longer the main source for U.S. imports. Mexico took its place last year.That seismic shift started in 2018 after President Trump signed into law a round of tariffs on many Chinese imports during his first term.

President-elect Donald Trump is threatening to impose sweeping new tariffs on Mexico, Canada and China as soon as he takes office as part of his efforts to crack down on illegal immigration and drugs.

The president-elect said that he would impose the across-the-board tariffs on Day 1 and that they would stay in place until the three countries halted the flow of drugs and migrants.
