BRUSSELS — The European Parliament’s top trade lawmakers failed on Wednesday to reach a common position on the EU-U.S. trade deal, in a move that risks fueling Washington’s impatience against the EU’s slow pace in finally implementing its side of a bargain struck last summer.

Negotiations will continue until next week, two people who attended a meeting of the lawmakers told POLITICO. One said that committee vote was penciled in for Feb. 24 and a final plenary vote for March. Both were granted anonymity to discuss the closed-door talks.

The meeting failed to clear remaining hurdles regarding the Parliament’s position on the removal of tariffs on U.S. industrial goods and lobsters — a precondition for Washington to reduce its own tariffs on European cars. 

Lawmakers from the international trade committee disagreed on the length of a sunset clause which would limit the proposals’ application to 18 to 36 months, as well as whether the EU should withdraw any tariff concessions until a solution is found between Brussels and Washington on the 50 percent tariff the Trump administration has put on steel derivatives.

With the EU still processing the shock of Trump’s threats against the territorial sovereignty of Greenland and the Kingdom of Denmark, the liberal Renew group and the Socialists & Democrats are pushing to Trump-proof the deal by inserting suspension clauses into enabling legislation in case the U.S. president turns hostile again. 

The center-right European People’s Party has pushed to sign off the deal following calls from EU leaders to unfreeze the implementation of the deal. 

Failure to reach an agreement on Wednesday throws into disarray the timeline for parliamentary approval, and further delays the start of negotiations with EU capitals and the European Commission.
