China has urged the United States to stop imposing one-sided tariffs. South Korea’s trade minister says the Supreme Court’s ruling against President Donald Trump’s tariffs has increased uncertainty for businesses. Financial markets took the news in stride, though, as most Asian share benchmarks advanced. While the court's decision may lower tariffs on some countries' exports to the U.S., it has raised questions about Trump's future moves, potentially disrupting arrangements worked out in trade negotiations since he announced sweeping tariffs on dozens of countries in April 2025. U.S. Trade Representative Jamieson Greer says the U.S. will stand by its trade deals and expects its partners to do the same.
