REUTERS — The United States and Iran clashed at the United Nations on Monday over Tehran’s nuclear program and the latter’s selection to be one of dozens of vice presidents at a month-long conference to review the nuclear Non-Proliferation Treaty.

The 11th conference to review implementation of the NPT, which came into force in 1970, began on Monday at the United Nations in New York. Different groups nominated 34 conference vice presidents, and the conference chair, Vietnam’s UN ambassador Do Hung Viet, said Iran was picked by “the group of non-aligned and other states.”

Christopher Yeaw, assistant secretary for the US Bureau of Arms Control and Nonproliferation, told the conference that Iran’s selection was an “affront” to the NPT.

He said it was “indisputable that Iran has long demonstrated its contempt for the non-proliferation commitments of the NPT,” and had refused to cooperate with the UN nuclear watchdog to resolve questions about its program.

He called Iran’s selection “beyond shameful and an embarrassment to the credibility of this conference.”

Reza Najafi, who serves as Tehran’s ambassador to the International Atomic Energy Agency, rejected the US statement as “baseless and politically motivated.”

“It is indefensible that the United States, as the only state ever to have used nuclear weapons, and the one that continues to expand and modernize its nuclear arsenal… seeks to position itself as an arbitrator of compliance,” he told the meeting.

The nuclear issue has been at the heart of the two-month war between Iran and the United States and Israel, with US President Donald Trump reiterating on Sunday that Iran can never have a nuclear weapon. The Islamic Republic avowedly seeks to destroy Israel, and funds and arms the Hezbollah and Hamas terror groups that openly share that goal.

Iran has long demanded Washington acknowledge its ostensible right to enrich uranium. It denies seeking nuclear weapons, but has enriched uranium to levels with no peaceful application and obstructed international oversight of nuclear facilities.

On Monday, Iranian sources disclosed Tehran’s latest proposal to end the conflict, which would set aside discussion of Tehran’s nuclear program until the war is ended and disputes over shipping from the Gulf are resolved.

Trump and his top national security aides met to discuss the conflict on Monday and White House spokeswoman Karoline Leavitt told reporters “the president’s red lines with respect to Iran have been made very, very clear, not just to the American public, but also to them as well.”
