CANBERRA -- Australia's Minister for Trade and Tourism Don Farrell on Saturday described US President Donald Trump's plan to double tariffs on steel and aluminum as "unjustified" and an act of economic "self harm."

Trump said on Friday that he plans to increase the tariff on steel and aluminum imports to the United States from 25 percent to 50 percent from June 4 to protect the domestic industry from foreign competition.

Responding to the announcement, Farrell said in a statement that Australia's position has been "consistent and clear" and that the federal government would continue to advocate strongly for the removal of the tariffs.

"These tariffs are unjustified and not the act of a friend," he said. "They are an act of economic self harm that will only hurt consumers and businesses who rely on free and fair trade."

Australian Prime Minister Anthony Albanese, whose Labor Party won a second term in government in a landslide at the May 3 election, in April described Trump's "Liberation Day" tariffs as "not the act of a friend".

The US administration in March decided against exempting Australia from the steel and aluminum tariffs. Albanese said at the time that the decision went against the "enduring friendship" of the two countries.
