China's tariffs against U.S. agricultural products take effect amid a U.S.-China tariff war. President Donald Trump has targeted China with tariffs, blasting the country for involvement with fentanyl pouring into the US.

Trump at first imposed 25% tariffs on Canadian and Mexican exports to the U.S., then exempted the duties on Mexican- and Canadian-made vehicles being transported into the U.S. and later by week’s end delayed the tariffs on almost all items for four weeks until April 2.
