The Trump administration announced new Iran-related sanctions on Tuesday intended to show its toughened stance toward the country despite having grudgingly recertified Iran’s compliance with the 2015 nuclear deal.

The sanctions, jointly announced by departments of State, Treasury and Justice, designated 18 individuals and entities that the administration said were involved in activities including missile development, weapons procurement, and software theft.

“The United States remains deeply concerned about Iran’s malign activities across the Middle East, which undermine regional stability, security, and prosperity,” the announcement said.

It came less than 12 hours after President Trump reluctantly agreed that Iran has been honoring the nuclear agreement that relaxed many sanctions on the country in return for verifiable curbs on its nuclear activities. Under an American law, the president must make such a declaration every 90 days.
