For von der Leyen, this will be her first face-to-face meeting with Trump since his return to the White House. The two have already spoken several times by phone about a trade deal.

Deadline

There's not much time left. President Trump has chosen August 1st as the deadline: if no deal is reached by then, many European goods face an additional 30 percent import tax.

According to international media, Trump, shortly before leaving office, called the chance of a deal"50-50." The European Commission announced Thursday that a deal was "within reach."

According to EU diplomats, Brussels and Washington are heading towards a 15 percent import tariff. Separate agreements may be reached for various sectors. Due to Trump's unpredictable nature, everyone in Brussels is warning that"nothing is certain."
