What to know as President Donald Trump imposes steep new tariffs on imports from Canada, Mexico and China, prompting retaliation and countermeasures.

President Trump agreed to delay tariffs on Mexico and Canada for a month after both countries pledged to do more to block drugs and migrants.

The move likely will trigger retaliation and risk igniting a trade war that could cause broad economic disruption for all countries involved.

Mexico and the United States have reached a one-month agreement to stave off tariffs and a looming trade war, the threat of which sent global markets tumbling early Monday. The 25% tariffs on Mexico were set to go into effect Tuesday,

Beijing announced tariffs on Tuesday on some American imports including crude oil, agricultural machinery and liquefied natural gas, in retaliation for the Trump administration’s imposition of 10% tariffs on Chinese imports into the United States.

Wall Street ends down but way off their lows. Trump delays Mexican tariffs a month for soliders at border. Then, Canada inks a pact.
