US President Donald Trump has extended the deadline for countries to finalise bilateral trade deals with the US from July 8 to July 31, giving a final three-week window before sweeping country-specific tariffs come into force on August 1.The extension is part of a broader trade offensive launched on April 2, when Trump identified 57 countries for special tariffs unless they signed new deals aligning with US trade interests. So far, only the UK and Vietnam have complied. A temporary ceasefire deal with China is also in place.
