USA, slapped major new tariffs on Chinese electric vehicles, advanced batteries, solar cells, steel, aluminum and medical equipment on Tuesday, taking potshots at Donald Trump along the way as he embraced a strategy that’s increasing friction between the world’s two largest economies.

The Democratic president said that Chinese government subsidies ensure the nation’s companies don’t have to turn a profit, giving them an unfair advantage in global trade.

“American workers can outwork and outcompete anyone as long as the competition is fair,” Biden said in the White House Rose Garden. “But for too long, it hasn’t been fair. For years, the Chinese government has poured state money into Chinese companies … it’s not competition, it’s cheating.”
