Biden Calls for Tariffs on Chinese Steel in Pittsburgh Pitch, Vying With Trump for Votes

President Biden on Wednesday called for major increases to some tariffs on steel and aluminum products from China, speaking to members of a national steelworkers union in Pittsburgh as he vies with former President Donald J. Trump for votes in Northern industrial states.

“These are strategic and targeted actions that are going to protect American workers and ensure fair competition,” Mr. Biden told a crowd of about 100 union members at the United Steelworkers, which endorsed him last month. “Meanwhile, my predecessor and the MAGA Republicans want across-the-board tariffs on all imports, from all countries, that could badly hurt American consumers.”

The Biden administration has argued that a flood of low-cost exports from China is undermining American-made products — jeopardizing Mr. Biden’s push to expand U.S. manufacturing, a central focus of his economic agenda.

In his speech, Mr. Biden said he would ask the U.S. trade representative, Katherine Tai, to increase tariffs to what White House officials said would be 25 percent on certain Chinese products that now face tariffs of 7.5 percent, or none at all, pending the outcome of an administration review of the China tariffs initially imposed under Mr. Trump.

“I want fair competition with China, not conflict,” Mr. Biden said, flanked by supporters and signs that read, “President Joe Biden: Standing With Workers.” “And we’re in a stronger competition to win the economic competition of the 21st century with China or anyone else because we’re investing in America, and American workers, again.”

The move is another effort by Mr. Biden to put up new barriers to trade with China in some industries. It could help him compete with Mr. Trump in a “tough on China” context with swing voters, though administration officials said elections did not motivate the move.
