On Saturday, Trump announced his administration would enact 25% tariffs on all products imported from Canada and Mexico – with the exception of Canadian oil, which received a 10% tariff – along with a 10% tariff on imports from China, as the president followed through on months of threats.

The White House claims the tariffs will remain until each of the countries addresses the “crisis” of fentanyl and illegal immigration coming into the United States. Here is what to know about the tariffs imposed on the countries and the places being threatened with tariffs.

Canada

The Great White North has been one of the closest allies to the U.S., but now the country faces 10% tariffs on energy imports into the U.S. and 25% tariffs on all other goods.

The White House has claimed that Canada has played a “central role” in the threat of the illegal flow of drugs and fentanyl into the U.S. and said that the blanket tariffs will remain until “compliance and cooperation of Canada is assured” in ending the crisis.

“We pay hundreds of Billions of Dollars to SUBSIDIZE Canada. Why? There is no reason. We don’t need anything they have. We have unlimited Energy, should make our own Cars, and have more Lumber than we can ever use. Without this massive subsidy, Canada ceases to exist as a viable Country. Harsh but true! Therefore, Canada should become our Cherished 51st State. Much lower taxes, and far better military protection for the people of Canada — AND NO TARIFFS!” Trump said in a post on Truth Social Sunday.

Canada has vowed to issue its own retaliatory tariffs, beginning with 25% tariffs on roughly $20 billion in products imported into Canada from the U.S. The products affected by the initial set of tariffs include cosmetics, appliances, dairy, sugar, and orange juice, among other products.

Canadian officials have said that there will be additional tariffs in the coming days if the United States’s tariffs are not revoked.

When Trump announced his plans to slap sweeping tariffs on Canada last year, Prime Minister Justin Trudeau responded by suggesting millions of dollars in spending to shore up security at the border. There were reported plans to spend as much as $1 billion, investing in new drones and changing the countries immigration policies.

Trump and Trudeau spoke Monday, and the president said he would speak with him again at 3 p.m.

Mexico

Trump announced a blanket 25% tariff on imports coming into the U.S. from Mexico on Saturday, while Mexico promised unspecified retaliatory measures to counter. On Monday, Mexican President Claudia Sheinbaum and Trump said that they had agreed to several measures, including a one-month pause on the tariffs.

In the declaration over the weekend, the White House had said the tariffs would remain “until Mexico cooperates with the United States in the fight against drug trafficking and on border security.”

Both Sheinbaum and Trump said Mexico agreed to send 10,000 soldiers to the U.S.-Mexico border to stop the flow of illegal immigrants and drugs between the border, while the U.S. had agreed to improve preventing weapons from being trafficked into Mexico. The agreement meant the tariffs by the U.S. would be delayed for at least a month as negotiations on additional items continue between the two countries.

As of Monday morning, the tariffs against Mexico are the only ones that have been halted.

China

Trump imposed a 10% blanket tariff on China, also taking issue with the country’s role in the fentanyl crisis, adding to previous tariffs imposed by the U.S. on imports from China.

In the president’s proclamation of the tariffs Saturday, he claimed that China “plays a central role in this challenge, not merely by failing to stem the ultimate source of many illicit drugs distributed in the United States, but by actively sustaining and expanding the business of poisoning our citizens.”

Trump also said that Chinese officials have refused to follow through with actions to combat the flow of fentanyl. The White House said the additional tariff would remain until “the full compliance and cooperation of the [Chinese] government is assured.”

A spokesperson for the Chinese foreign ministry blasted the tariffs, saying on Sunday that “China firmly deplores and opposes this move and will take necessary countermeasures to defend its legitimate rights and interests.”

The Chinese spokesperson also claimed that the tariffs “severely violate” World Trade Organization rules.

European Union

Trump has not imposed any tariffs on the European Union, but he has warned that he will place tariffs on their products “pretty soon.”

Speaking to reporters Sunday night, Trump said that tariffs would “definitely happen with the European Union,” claiming that they have taken advantage of the U.S. regarding trade.

Someone close to the Trump administration told the Telegraph the president is considering 10% tariffs on all imports from the European Union, and the sparring with Canada and Mexico is an exploratory mission to see “what he can get away with.”

Unlike Canada and Mexico, Trump isn’t worried about the EU’s borders. Rather, his gripe is that Brussels runs a large trade surplus with the U.S.

“They don’t take our cars, they don’t take our farm products,” Trump said. “They take almost nothing, and we take everything: from the millions of cars, tremendous amounts of food and farm products.”

“The European Union has treated us so terribly,” Trump said.

EU Foreign Policy Chief Kaja Kallas told reporters Monday that the EU is “listening carefully” to Trump but warned against a trade war.

“We were listening carefully to those words and of course we are preparing also on our side. But what is clear is that there are no winners in trade wars. If the United States starts the trade war, then the one laughing on the side is China. We are very interlinked,” Kallas said.

“We need America and America needs us as well. The tariffs increased costs. They are not good for the jobs, not good for the customers either. That is clear,” she added.

EU policymakers have suggested levying up to 50% tariffs on select U.S. imports if Trump carries through on his threat.

Trump, in the Sunday remarks to reporters, said that the United Kingdom was also “out of line” but expressed confidence that it could be worked out.
