The US State Department on Monday repeated that it remains open to meeting with Iranian officials directly to discuss the nuclear deal and other issues after Iran’s foreign minister said Tehran would consider this but had made no decisions.

Speaking at a briefing, State Department spokesman Ned Price also said the US had not made Iran’s releasing four Americans a condition of reaching an agreement for both nations to resume compliance with the nuclear deal, saying that achieving such an agreement was an uncertain proposition.

Earlier on Monday, the State Department said the US was prepared to hold direct talks with Iran after Tehran said it would consider such an option.

“We are prepared to meet directly,” a State Department spokesperson said.

“We have long held the position that it would be more productive to engage with Iran directly, on both JCPOA negotiations and other issues,” the spokesperson said, referring to the nuclear deal between Iran and major powers.

The spokesperson said that meeting directly would allow “more efficient communication” needed to reach an understanding on what is needed to resuscitate the 2015 deal.

“Given the pace of Iran’s nuclear advances, we are almost out of time to reach an understanding on mutual return to full implementation of the JCPOA,” the official said.

The comments came after Iran said Monday it will consider direct talks with the United States during ongoing negotiations in Vienna aimed at restoring the deal.

“Iran is not currently talking with the US directly,” Hossein Amir-Abdollahian said in televised remarks.

“But, if during the negotiation process we get to a point that reaching a good agreement with solid guarantees requires a level of talks with the US, we will not ignore that in our work schedule,” he added.
