The decision by Switzerland's highest executive authority was made after consultation with parliament's foreign affairs committees and the country's cantons and follows a non-binding Swiss-U.S.-Liechtenstein "framework" agreed on November 14.
This was aimed at reducing U.S. tariffs on Swiss imports and paving the way for a comprehensive agreement.
Under that framework, Washington set a 15% ceiling on country-specific additional tariffs on Swiss imports, down from 39%, with the change applied retroactively from November 14.
