Australian Prime Minister Anthony Albanese says U.S. tariffs on Australian steel and aluminum are unjustified, but his government will not retaliate with its own tariffs.

Australia has failed to secure an exemption from US steel and aluminum tariffs despite a lobbying campaign by Prime Minister Anthony Albanese’s government, in a blow to relations between the two longtime allies.

Australia will not impose reciprocal tariffs on the United States, Prime Minister Anthony Albanese said on Wednesday, after President Donald Trump ruled out exemptions or exceptions for all countries on steel and aluminium tariffs.
