SAN FRANCISCO, Oct 27 — A tariff truce between the European Union and United States is potentially at risk due to a multibillion-dollar loan approved by the bloc’s investment bank for Airbus this summer, President Donald Trump’s top trade official said yesterday.

US Trade Representative Jamieson Greer expressed concern that his office had received “no details about this loan” and pressed for the situation to be “resolved as soon as possible.”

“I had sincerely hoped that trade-distorting European subsidies to Airbus were a thing of the past,” Greer said in a statement. The EU has rejected the claim.

“This situation injects substantial uncertainty into transatlantic trade in the aerospace sector,” he continued.
