Australia may challenge U.S. steel and aluminum tariffs at WTO as Trump doubles levies.

Australia is considering challenging the U.S. steel and aluminum tariffs at the World Trade Organization (WTO). President Trump plans to double levies on foreign steel from 25% to 50%, affecting Australia's 10% baseline tariff. Prime Minister Albanese calls it "economic self-harm" and plans to discuss it with Trump at the G7 summit. Australia aims to secure an exemption rather than retaliate, while Trade Minister Farrell will argue for the tariffs' removal. Canada has already challenged the U.S. at the WTO over similar issues.
