Tehran says US embassy not a priority, but welcomes investment

The warning came just hours before Rafael Grossi, the director of the International Atomic Energy Agency (IAEA) was due to arrive in Tehran.

“If a serious military threat emerges, Iran will expel the inspectors, cut their access, and move nuclear materials to locations beyond reach,” Farhikhtegan wrote.

It accused the IAEA of political bias and said Grossi’s previous visits had yielded cooperation only from Iran. “Despite Iran’s compliance, the agency has published reports that fuel anti-Iran resolutions,” it added.

Grossi’s visit coincides with the anticipated second round of negotiations between Iranian and US officials. While details of the agenda remain unclear, the talks have stirred strong opposition across Iran’s ultraconservative press, particularly following mixed signals from Washington.

After the first round of negotiations in Oman on Saturday, US envoy Steve Witkoff said Monday that Iran might be allowed to continue low-level enrichment under a deal resembling the original JCPOA. But on Tuesday, he tweeted that “Iran must stop and eliminate its nuclear enrichment and weaponization program.”

“A deal with Iran will only be completed if it is a Trump deal," the special envoy said.

The hardline daily Kayhan, overseen by Supreme Leader Ali Khamenei's office, focused on Tuesday on Witkoff’s new comments and accused the US of using diplomacy to mask coercive aims.

Editor Hossein Shariatmadari wrote that Witkoff’s offer in earlier talks had “no more value than a cheap political ruse,” adding that the US had “flunked its first test of sincerity.”

“The Americans pretend to negotiate, but their demands expose their true intentions—disarming the Islamic Republic and and plowing its land and people,” Shariatmadari said.

Meanwhile, senior Iranian military adviser Brigadier General Hossein Ashtari told ILNA news agency that Tehran’s stance would not change under pressure.

“Our positions are firm. It is the Americans and the Zionists who must adjust to Iran’s terms,” he said.

With nuclear inspectors in Tehran and diplomacy on a knife’s edge, Iran’s conservative media are pushing a dual message: cooperation remains conditional, but retaliation, if provoked, would be decisive.

With uncertainty over the venue and agenda clouding the second round of Iran-US talks, Iranians are growing anxious that President Donald Trump’s patience may soon run out.

IAEA chief Rafael Grossi will visit Tehran on Wednesday for meetings with senior Iranian officials, including the foreign minister and head of the atomic energy agency, Iranian media reported.

Iran’s Foreign Minister Abbas Araghchi said on Wednesday that uranium enrichment is not open to negotiation, reaffirming Tehran’s red line as the United States signals it seeks to end Iran’s nuclear program entirely.

“The principle of enrichment is not subject to negotiation,” Araghchi said. His remarks came a day after the White House stated that President Donald Trump wants the complete dismantling of Iran’s nuclear program.

Araghchi added that talks could move forward if Washington adopts a more constructive approach. “If the Americans come with a constructive approach, I’m hopeful we can begin talks on the framework of a possible agreement,” he said. “But if they continue with contradictory and conflicting positions, we will face difficulties.”

He also announced that he is carrying a message from Supreme Leader Ali Khamenei to Russian President Vladimir Putin during his upcoming visit to Moscow.

Iran will not bow to pressure from any foreign power and will respond firmly to threats, Judiciary Spokesman Asghar Jahangir said on Wednesday during his first press conference of the Iranian year.

“What is certain is that Iran stands firm and does not submit to pressure from any power,” he said.

“This option for indirect talks comes from the Islamic Republic’s decision to fight for national interests while also using the window of diplomacy,” he added.
