BRUSSELS (Reuters) -The European Union is working closely with U.S. President Donald Trump's administration to reach a trade deal, but Brussels is getting ready for all scenarios, European Commission President Ursula von der Leyen said on Wednesday.

"We stick to our principles, we defend our interests, we continue to work in good faith, and we get ready for all scenarios," von der Leyen told the European Parliament.

Trump signed an executive order on Monday extending the date on which so-called "reciprocal" tariffs will take effect to August 1.

The previous deadline had been Wednesday.

In a wave of letters, Trump has begun informing a range of trading partners from Japan to Myanmar of sharply higher tariffs on goods they sell into the United States.

But EU sources told Reuters the European Union would not be among the recipients of a similar letter.
