The U.S. plans to announce more sanctions against Iran, but President Donald Trump is also willing to negotiate with Iranian leaders with "no preconditions" to ensure the Islamic Republic never acquires a nuclear weapon.
The president's comments were echoed by Secretary of State Michael Pompeo, who on Sunday referenced a "significant set of new sanctions" to come on Monday as he prepared to visit Saudi Arabia and the United Arab Emirates for talks to rally "a global coalition to push back against Iran."
Some 80 percent of the Iranian economy is already sanctioned, and the new ones will be a further effort to ensure that Tehran's ability to grow its economy "becomes more and more difficult," Pompeo told reporters.
