Existing American tariffs already restrict steel and aluminum shipments from China, which is now flooding other markets with its exports instead.

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.

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.

China's latest tariffs on US goods include a 15% border tax on imports of US coal and liquefied natural gas products. There is also a 10% tariff on American crude oil, agricultural machinery and large-engine cars.

The trade dispute between the US and China has gone into another round after President Donald Trump recently imposed a 10% tariff on all Chinese imports to the US. It piles on top of already existing levies.
