US and allies clash with Russia and China at UN over Iran nuclear program

UN Security Council Debate on Iran's Nuclear Program

March 12 (Reuters) - The U.S. and Western allies clashed with Russia and China on Thursday over Iran's nuclear intentions, as Washington sought at the United Nations to further justify the war it launched on Iran two weeks ago.

Security Council Meeting and Sanctions Committee

At a meeting of the 15-member U.N. Security Council, which is chaired this month by the U.S., Russia and China moved unsuccessfully to block a discussion about a committee established to oversee and enforce U.N. sanctions on Iran. They were overruled 11-2 with two abstentions.

US Accusations Against Russia and China

Addressing the council, U.S. envoy to the United Nations Mike Waltz accused Moscow and Beijing of seeking to protect Tehran by blocking the work of the so-called 1737 Committee.

Calls for Arms Embargo and Sanctions

"All member states of the United Nations should be implementing an arms embargo against Iran, banning the transfer and trade of missile technology, and freezing relevant financial assets," Waltz said.

"The U.N. provisions to be re-imposed are not arbitrary, but instead, narrowly scoped to address the threat posed by Iran's nuclear, missile and conventional arms programs and Iran's ongoing support for terrorism," he said.

Waltz said both China and Russia did not want a functional sanctions committee "because they want to protect their partner, Iran, and continue to maintain defense cooperation that is now once again prohibited."

IAEA Findings and International Concerns

Waltz noted that last week the U.N.'s International Atomic Energy Agency had reiterated that Iran was the only state in the world without nuclear weapons to have produced and accumulated uranium enriched up to 60 percent, and had refused to provide the IAEA access to this stockpile.

Responses from Russia, China, and Iran

Russian and Chinese Criticism of US Actions

Russia's U.N. ambassador Vasily Nebenzya accused the U.S. and its allies of whipping up "hysteria surrounding supposed plans Iran had to get a nuclear weapon" that were never corroborated by IAEA reports.

"This was done in order to undertake yet another military venture against Tehran and to ensure great escalation of the situation in the Middle East and beyond," he said.

China's representative, Fu Cong, called Washington the "instigator" of the Iranian nuclear crisis and said it had "resorted to blatant use of force against Iran during the negotiation process, which rendered the diplomatic efforts futile."

Iran's Position on Its Nuclear Program

Iran's UN ambassador, Amir Saeid Iravani, told reporters later on Thursday that Iran's nuclear program "has always been exclusively peaceful," and Tehran would not recognize any attempt to enforce sanctions against it.

Western Allies' Justification for Sanctions

US and Allies Cite Nuclear Threat

U.S. President Donald Trump has used Iran's nuclear program to justify his war on Iran. He said this month that Iran would have had a nuclear weapon within two weeks had the ⁠U.S. not struck three key nuclear sites in June, a claim sources have said was not supported by U.S. intelligence assessments.

Britain and France told the Security Council that re-imposing sanctions on Iran was justified by Tehran's failure to address concerns about its nuclear program.

France's Concerns Over Iran's Nuclear Stockpile

France said the IAEA was no longer able to guarantee the peaceful nature of the program and that Tehran's nuclear stockpile was sufficient for 10 nuclear devices.
