What we're covering
• Historic global trade war: President Donald Trump declared a US economic emergency and announced tariffs of at least 10% across all countries, with rates even higher for 60 countries or trading blocs that have a high trade deficit with the US. Auto tariffs are now in effect.
• China hit hardest: China, the second top exporter to the US behind Mexico, will now face a 54% tariff and has vowed to hit back. Canada and the EU, also top trade partners, are preparing countermeasures.
• Global markets rattled: After-hours US stock markets fell sharply, as did Asian and European markets, after the tariff announcement. And gold hit a new record high as investors seek safer investments. Leading economists told CNN they feared the tariffs could lead to a global recession.
