With an escalation in President Trump’s trade war possible as early as Thursday, retaliatory tariffs threaten U.S. companies employing some 11 million workers, according to an Axios analysis.

If Trump proceeds this week or later, as experts expect him to, China has said it will retaliate with tariffs on $60 billion in U.S. exports.

That’s on top of 25% and 10% tariffs enacted, respectively, on steel and aluminum imports from Canada, China, Mexico and the European Union, and by those countries against the U.S.
