European Trade Commissioner Phil Hogan is in Washington this week for a series of meetings.
He will hold talks with senior members of the Trump administration amid major trade tensions between the United States and the European Union.
Among the items up for discussion will be a row over France's digital services tax on tech giants.
US President Donald Trump has threatened to retaliate by imposing tariffs of up to 100% on $2.4bn of French wines, make-up, leather handbags and other goods.
In a separate trade row, Irish butter, cheese, liqueurs and pork products were hit with US tariffs in October.
The duties, targeting a range of EU goods, were announced in retaliation for European aircraft subsidies.
The EU is pushing for tariffs of around $10bn on US products in a parallel process to be decided by the World Trade Organisation.
President Trump is a frequent critic of the EU and in the past has described the bloc as "a foe" when it comes to trade.
In 2018, the US announced tariffs on European steel and aluminium and the Trump administration has threatened to impose duties on European cars.
In September, Mr Hogan told RTÉ's Today with Sean O'Rourke that the EU would seek to get President Trump to see "the error of his ways" and abandon some of his "reckless" trade policies.
