US to double tariffs on steel and aluminium imports to 50%, Donald Trump says | BBC News

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 reducing reliance on China. Trump also said that $14bn would be invested in the area's steel production through a partnership between US Steel and Japan's Nippon Steel, though he later told reporters he had yet to see or approve the final deal. The announcement is the latest turn in Trump's rollercoaster approach to tariffs since re-entering office in January.
