"He is calling the meeting to address Iran’s violations of international law," Haley said at a press conference Tuesday afternoon, adding that the meeting will also address the “instability” Iran is sowing throughout the Middle East region.
“There is a growing concern about Iran," Haley said, referencing Tehran's ballistic missile ambitions, weapons sales to Yemen and support for terrorist groups. "Some are old things, some are new things."
Trump is also expected to chair a session of the U.N. Security Council on an “important regional issue," the U.S. mission to the U.N. said earlier Tuesday.
The 73rd session of the U.N. General Assembly is set to kick off on Sept. 18 in New York. Trump is expected make an appearance at the end of the month during “high-level week,” which begins on Sept. 24, with a meeting on global peace. Other scheduled meetings will address reducing threats of nuclear weapons and disease prevention.
The meeting follows the Trump administration’s decision to withdraw from the Iran nuclear deal in May and re-impose sanctions on Tehran, in a major break with U.S. European allies. Iran’s foreign minister said in August that U.S. and Iranian officials would not meet at the U.N. General Assembly.
Haley said Tuesday that Iranian President Hassan Rouhani could attend the meeting if he should choose.
Separately, the White House said Tuesday that Trump and South Korean President Moon Jae-in would huddle on the sidelines of the summit to discuss North Korea and efforts to rein in Pyongyang’s nuclear program.
