U.S. President Donald Trump said on Tuesday he intends to impose auto tariffs "in the neighborhood of 25%" and similar duties on semiconductors and pharmaceutical imports, the latest in a series of measures threatening to upend international trade.

President Donald Trump doubled down on his extraordinary push for more balanced trade, ordering on Thursday that agencies should investigate plans for new reciprocal tariffs that could boost America’s revenue — but could also ignite a global trade war and add to America’s rebounding inflation problem.

In starting a process to impose reciprocal tariffs on American trading partners, the White House is sowing uncertainty and risking inflation.
