LME copper prices recover from four-week low after Trump delays tariffs on Canada and Mexico, easing trade war concerns. Benchmark copper is up 0.6% at $9,155 a metric ton. Trump still plans to impose tariffs on China, but will speak with Chinese President Xi Jinping to seek a deal. U.S. companies may look to the Middle East, India, Chile, and Peru for aluminium and copper to avoid tariffs. China's factory activity grew at a slower pace in January.
