European Union leaders discussed new proposals from the United States on a trade deal at a summit in Brussels on Thursday, with Commission President Ursula von der Leyen not ruling out tariff talks could fail and saying "all options remain on the table".

The proposal, which one official described as an "outline" containing a couple of points, came as EU leaders were meeting at a summit in Brussels, less than two weeks before a July 9 deadline set by U.S. President Donald Trump for a deal to avert higher U.S. tariffs.

E.U. chief Ursula von der Leyen said the bloc was ready for a trade deal with Washington, but hinted at preparations for countermeasures if a July 9 deadline was not reached.
