Biden says Iranian enrichment to 60% unhelpful, but glad about talks

Iran on Friday said it had begun enriching uranium to 60%, its highest level ever and a step closer to the 90% that is weapons grade, at its Natanz plant, where an explosion occurred earlier this week that Tehran blamed on Israel.

"We do not support and do not think it's at all helpful that Iran is saying it's going to move to enrich to 60 percent," Biden told reporters in Washington during a joint news conference with Japanese Prime Minister Yoshihide Suga.

"We are, though, nonetheless pleased that Iran has continued to agree to engage in discussions - indirect discussions - with us and with our partners on how we move forward and what is needed to allow us to move back into the (nuclear deal) ... without us making concessions that we are just not willing to make," Biden added.

Iran had in recent months already raised enrichment to 20% purity, a level at which uranium is considered to be highly enriched and a significant step toward weapons-grade.

A 2015 deal with world powers to rein in Iran's nuclear ambitions in return for the lifting of sanctions had capped the level of purity at 3.67%. Iran denies seeking a nuclear weapon.

"We are producing about 9 grams of 60% enriched uranium an hour," Ali Akbar Salehi, head of the Atomic Energy Organization of Iran, told state television.

"But we have to work on arrangements ... to drop it to 5 grams per hour. But then we will simultaneously produce 20% (uranium)," Salehi said.

Earlier, Iran's parliament speaker Mohammad Baqer Qalibaf said Iranian scientists had successfully started enriching 60% uranium at 40 minutes past midnight.

"The will of the Iranian nation makes miracles that thwart any conspiracy," Qalibaf wrote on Twitter.

In Vienna, a spokesman for the United Nations nuclear watchdog IAEA declined to comment on the Iranian statements about 60% enrichment.

Asked if Iran's move was a sign that Tehran is not serious about returning to the nuclear deal, Biden replied: "The discussions are under way. I think it's premature to make a judgment as to what the outcome will be. But we are still talking."

Iran and global powers are meeting in Vienna to try to rescue the 2015 nuclear deal abandoned by former U.S. President Donald Trump three years ago - an effort potentially complicated by Tehran's decision to ramp up uranium enrichment.

The talks will carry on for several days before breaking so that Iranian and U.S. officials can return home for consultations, a European Union official said on Friday. read more

"We have this (Iranian) decision to go for 60% enrichment. Obviously this is not making the negotiation easier," the EU official told reporters, calling what happened at Natanz "deliberate sabotage".

Abbas Araqchi, Iran's chief negotiator at the talks, said on Tuesday that Iran would activate 1,000 advanced centrifuge machines at Natanz.
