President Donald Trump has threatened 25 percent tariffs on European cars and trucks, in dissatisfaction that the EU has not yet finalized last year's trade deal.
However, the EU side is prepared to respond.
"We are ready for all scenarios," von der Leyen said at a press conference after a meeting with the Prime Minister of Armenia in Yerevan.
The work of approving the US deal is still ongoing in the EU, where the Council of Ministers and Parliament are due to negotiate on Wednesday.
In Brussels, Finance Minister Elisabeth Svantesson (M) sighs heavily about Trump.
"I just feel incredibly tired. It's hard to take him seriously in the end," Svantesson says.
