Donald Trump pushed back a deadline for countries to reach a trade deal with America from July 9th to August 1st, though he maintained his threat to impose stiff tariffs should those talks fail. Japan and South Korea, for example, would face duties of 25%. The EU, which is hoping to strike a preliminary deal, has so far been excluded from the latest broadside. The president is piling the pressure on countries that have not yet reached a deal. Only Britain and Vietnam have agreed to “frameworks” so far. Canada, China and Mexico are being treated separately.
