US opposes European plan to censure Iran over nuclear work

BERLIN—The Biden administration is pressing European allies to back off plans to rebuke Iran for advances in its nuclear program as it seeks to keep tensions with Tehran from escalating before the autumn’s U.S. presidential election, according to diplomats involved in discussions.

The U.S. is arguing against an effort by Britain and France to censure Iran at the International Atomic Energy Agency’s member state board in early June, the diplomats said. The U.S. has pressed a number of other countries to abstain in a censure vote, saying that is what Washington will do, they said.

U.S. officials deny lobbying against a resolution.

The Biden administration has long said it is seeking a diplomatic solution on Iran’s nuclear program.

European diplomats have warned that failure to take action would undermine the authority of the IAEA, which polices nonproliferation of nuclear weapons. They say it also weakens the credibility of Western pressure on Iran. And they are frustrated over what they see as U.S. efforts to undermine their approach.

A U.S. official said Washington is “tightly coordinated" with its European partners ahead of the IAEA board meeting next month: “Any speculation about decisions is premature."

“We are increasing pressure on Iran through sanctions and international isolation," the official added, citing
