Trump's renewed firmness on that deadline came after he posted a flurry of letters warning world leaders, threatening to impose tariffs similar to those he announced in April. On

Trump said on Monday that the US would impose 25 per cent tariffs on Tunisia, Malaysia and Kazakhstan; 30 per cent on South Africa, Bosnia and Herzegovina; 32 per cent on Indonesia; 35 per cent on Serbia and Bangladesh; 36 per cent on Cambodia and Thailand and 40 per cent on Laos and Myanmar.

According to Trump's letters, autos would be tariffed separately at the standard 25 per cent worldwide, while steel and aluminum imports would be taxed on 50 per cent.
