Nascent talks aimed at bringing the United States back into the 2015 nuclear deal with Iran broke Friday without any immediate signs of progress on the thorny issues dividing Washington and Tehran, but with delegates talking of a constructive atmosphere and resolving to continue the discussions.

Two working groups that have been meeting in Vienna since Tuesday to brainstorm ways to secure the lifting of American sanctions and Iran’s return to compliance with the deal reported their initial progress to a joint commission of diplomats from the world powers that remain in the deal – France, Germany, Britain, China and Russia.

Russian delegate Mikhail Ulyanov tweeted that participants had “noted with satisfaction the initial progress made.”

“The commission will reconvene next week in order to maintain the positive momentum,” he said.

The talks took place without the U.S., which unilaterally left the nuclear deal, known as the Joint Comprehensive Plan of Action, in 2018, under then-president Donald Trump. He embarked on a campaign of “maximum pressure” by restoring previous sanctions and adding new ones on Iran.

But an American delegation headed by the Biden administration’s special envoy for Iran, Rob Malley, also has been in the Austrian capital this week. Representatives from the other world powers have been shuttling between the U.S. and the Iranians to facilitate indirect talks.

After the U.S. withdrawal, Iran has been openly violating the deal’s restrictions, steadily increasing its stockpile of enriched uranium, increasing the purity it is enriching, and installing and operating new, more efficient centrifuges, among other things.

President Joe Biden, who was vice-president under Barack Obama when the original deal was negotiated, has said he wants to bring the U.S. back into the deal but that Iran must reverse its violations.

Iran argues that Washington’s departure from the deal was the first violation and that the U.S. must make the first move and remove sanctions before Iran returns to compliance.

As the talks opened, China’s representative in Vienna, Wang Qun, backed the Iranian position. “We, in China, have a saying to the effect that the one who ties the knot should be the one to undo it,” he said.

Complicating matters further, Tehran argues that the U.S. needs to drop all sanctions, including measures not related to the deal and Iran’s nuclear program.

Iran’s ambassador to the International Atomic Energy Agency, Kazem Gharibabadi, showed no sign of backing off that position in comments posted Friday on the website of Iran’s Supreme Leader Ayatollah Ali Khamenei.

All sanctions imposed by Mr. Trump’s administration, including “sanctions imposed under non-nuclear pretexts … must be lifted completely,” he said.

Still, Iranian Deputy Foreign Minister Abbas Araghchi told Iran’s Press TV on Friday that the talks in Vienna had not been fruitless.

“In my opinion, these negotiations are moving forward, very constructive and useful, but it is too early to say whether we are moving forward in a positive direction,” he said. “The atmosphere of the meetings are constructive, but we are still far from the point where we can hope for a positive trend, although we are not disappointed.”

The U.S. delegation has said little about the continuing talks. Mr. Malley on Thursday tweeted his thanks to Austria for hosting it as “we engage in principled diplomacy to determine if Iran and the United States can find a way back into compliance with the JCPOA,” as the nuclear deal is known.

Enrique Mora, the European Union official who chaired the talks, said he would continue to shuttle between the U.S. and Iranian delegations, as well as others next week.

“The participants emphasized their resolve to further pursue the ongoing joint diplomatic effort,” he said in a statement.

The deal’s ultimate goal is to prevent Iran from developing a nuclear bomb, something it insists it does not want to do. Iran now has enough enriched uranium to make a bomb, but nowhere near the amount it had before the nuclear deal was signed.

In pulling the U.S. out, Mr. Trump said the deal was a bad one and needed to be renegotiated to include other issues, such as Iran’s ballistic missile program and regional influence. Those concerns are shared by other members of the agreement, but they have maintained these issues should be addressed outside the nuclear deal. They are not part of the current talks.

America’s departure from the deal under Mr. Trump has also raised Iranian concerns that even if sanctions are dropped and Iran returns to compliance, the U.S. could pivot again under a future president.

Mr. Gharibabadi said Iran raised that issue in the Vienna talks.

Meanwhile, issues looming in the near future may make negotiations even more complicated.

In late February, Iran began restricting international inspections of its nuclear facilities, but under a last-minute deal worked out during a trip to Tehran by Rafael Grossi, the head of the Vienna-based UN atomic watchdog, some access was preserved.

Under that agreement, Iran will no longer share surveillance footage of its nuclear facilities with the IAEA but has promised to preserve the tapes for three months. It will then hand them over to the IAEA if it is granted sanctions relief. Otherwise, Iran has vowed to erase the recordings, narrowing the window for a diplomatic breakthrough.

Iranian Foreign Minister Mohammad Javad Zarif in March also urged the U.S. to act quickly, noting that as his country’s June presidential election approaches, Washington will find itself dealing with a government unable to make progress in the nuclear talks.
