The United States will move to impose 25-percent tariffs on steel and aluminum imports this week, President Donald Trump said Sunday, the latest in a slew of trade levies he has announced.

Trump told reporters aboard Air Force One that the tariffs, which he will announce on Monday, will apply to “any steel coming into the United States,” adding this will also affect aluminum.

Trump imposed similar tariffs during his 2017-2021 presidency to protect US industries, which he believed faced unfair competition from Asian and European countries.

Canada — which Trump has already threatened with tariffs — is the largest source of steel and aluminum imports to the United States, according to US trade data. Brazil, Mexico and South Korea are also major steel providers to the country.

On Sunday, the Republican billionaire also said he would announce “reciprocal tariffs” to match his government’s levies to the rates charged by other countries on US products.

“Every country will be reciprocal,” Trump said, adding that he would make a detailed announcement on the tariffs on Tuesday or Wednesday.

In response, French foreign minister Jean-Noel Barrot said Monday the European Union will counter in kind and “replicate” any tariffs imposed on it.

“There is no hesitation when it comes to defending our interests,” he added during an interview with broadcaster TF1.

Trump has already shown his fondness for weaponizing the United States’ financial power, ordering tariffs on key trade partners China, Mexico and Canada soon after he took office.

He paused 25-percent levies against Canada and Mexico for a month after both countries vowed to step up measures to counter flows of the drug fentanyl and the crossing of undocumented migrants into the United States.

The tariffs against China went ahead, however, with products entering the United States facing additional levies of 10 percent since Tuesday.

Beijing responded with targeted tariffs on certain US products such as coal and liquefied natural gas, which will come into play on Monday.

The new Chinese tariffs cover $14 billion worth of US goods, while the tariffs announced by Trump cover $525 billion worth of Chinese goods, according to Goldman Sachs.

Trump has also pledged tariffs on the European Union and said that he would soon announce unspecified “reciprocal tariffs.”

French President Emmanuel Macron vowed in an interview aired Sunday to go head-to-head with Trump over his financial threats to Europe, though he said that the United States should focus its efforts on China rather than the European Union.
