President Donald Trump and EU chief Ursula von der Leyen meet Sunday in Scotland in a decisive push to resolve a months-long transatlantic trade standoff -- with the US leader putting the chances of a deal at one in two.

The EU says its negotiators are working "might and main" on a deal, but the decision rests with US President Trump.

European Commission President Ursula von der Leyen is set to meet U.S. President Donald Trump on Sunday to clinch a trade deal for Europe that would likely see a 15% baseline tariff on most EU goods,

The European Union and the US are progressing toward an agreement that would set a 15% tariff for most imports, according to diplomats briefed on the negotiations.

The European Union is reportedly preparing to impose 30% tariffs on up to €100 billion ($117.2 billion) of U.S. goods if no trade deal is reached and President Trump follows through with his threat to raise tariffs on EU exports after August 1.

As the two biggest economic targets in Donald Trump’s trade war, some analysts thought the European Union and China could move closer together and stake out common ground.

EU trade ministers have agreed that U.S. President Donald Trump’s 30% tariffs announced on the European Union are “absolutely unacceptable,” and they are studying a new set of countermeasures to respond to the move.

President Trump’s threatened 30% tariffs on the EU might prompt some businesses to take another look at the U.K.

A threatened 30% tariff on European wines would hurt many U.S. companies while hiking prices at home and in restaurants, industry experts warn.
