[President Donald Trump has announced 
that the European Union and Mexico
 will face a 30% tariff on imports to the US
 from 1 August.
He warned he would impose even
 higher import taxes if either of the
 US trading partners decided to retaliate.
The announcement was made in two
 letters posted on Trump's Truth Social website. 
Similar letters were sent this week
 to several other countries.
The 27-member EU - America's biggest 
trading partner - said earlier this week
 it hoped to agree a deal with 
Washington before 1 August.]
