The rapid-fire shots of tariffs and import curbs hearken back to Trump’s first term in office, when the U.S. and China engaged in a trade war that spanned most of Trump’s first four years in office and was continued to a certain extent under his successor, Joe Biden.

WASHINGTON — President Trump has paused imposing tariffs on small-value packages arriving from China, apparently to give federal agencies time to sort out how to process millions of such shipments that have come through the U.S. border every day without paying taxes.

Trump said the United States trade surplus with Australia was one of the reasons he was considering an exemption from the tariffs.
