President Donald Trump has announced the US will double its current tariff rate on steel and aluminium imports from 25% to 50%, starting on Wednesday.
Speaking at a rally in Pittsburgh, Pennsylvania, Trump said the move would help boost the local steel industry and national supply, while decreasing reliance on China.
Trump also said that $14bn would be invested into the area's steel production through a partnership between US Steel and Japan's Nippon Steel. Details on the partnership are still unclear and both companies have yet to confirm a deal.
