LONDON: US trading partners in Asia weighed fresh uncertainties this weekend after President Donald Trump announced a new tariff on imports, hours after the Supreme Court struck down many of the sweeping levies he used to launch a global trade war. The court’s ruling invalidated a number of tariffs that the Trump administration had imposed on Asian export powerhouses from China and South Korea to Japan and Taiwan, the world’s largest chipmaker and a key player in tech supply chains.

Refunds for importers and negotiations for new trade deals are among issues to watch after the Supreme Court overturned Trump's tariffs.
