We have a few cards to play, he says to the radio.
A trade war with the USA will hit export companies and be inflationary with more expensive and perhaps fewer products for consumers.
The most important thing now, according to Dousa, is to find new markets for European companies.
He points to the so-called Mercosur agreement, which the EU is about to enter into with several South American countries, including Brazil and Uruguay, after many years of negotiations.
Sweden is now pushing for progress to be made with India, Indonesia, and Malaysia, says Dousa to Ekot.
At the same time, the EU is criticizing Trump's tariffs on Canada, Mexico, and China. An EU spokesperson says that the union "regrets the US decision".
Tariffs create unnecessary economic disturbances and drive inflation. They are harmful to all parties, says the spokesperson according to the AFP news agency.
The spokesperson notes that "a lot is at stake".
The EU will respond firmly to all trading partners that unfairly or arbitrarily impose tariffs on EU goods.
