US trade policy faces fresh uncertainty after Supreme Court blocks Trump's emergency tariff authority. The administration insists existing bilateral deals with China, EU, Japan, and South Korea remain intact, with US Trade Representative Jamieson Greer emphasizing commitment to negotiated arrangements. However, trading partners express skepticism. The European Parliament's trade chief plans to freeze EU ratification of a US trade deal pending policy clarification, while India postpones Washington talks citing similar concerns. Trump's 15% global tariff announcement Saturday compounds confusion. The administration claims alternative trade tools, including investigations of unfair practices, provide sufficient leverage. Markets remain volatile as geopolitical trade tensions persist ahead of Trump's planned March visit to China to meet President Xi Jinping.
