Iran Freezes US Talks Over Interim Deal

Iran has ruled out direct negotiations with the United States unless Washington first resolves what Tehran describes as violations of a June 2026 memorandum of understanding, reinforcing a diplomatic impasse even as indirect negotiations continue through Oman over maritime security in the Strait of Hormuz.

Foreign Minister Abbas Araqchi said Iran’s position remains unchanged, insisting that negotiations cannot resume until the United States ends the alleged breaches and compensates Tehran for their consequences.

“Until the violations of the memorandum of understanding by the United States come to an end and the United States compensates for what it has violated, from our perspective, there is no possibility of resuming negotiations,” Araqchi said.

Iranian Foreign Ministry spokesperson Esmaeil Baghaei reiterated the government’s position, stating that Iran is “not currently negotiating with the U.S.,” underscoring Tehran’s refusal to reopen direct diplomatic channels.

Tehran Rejects Pressure as Diplomatic Deadlock Deepens

Iran’s latest remarks follow comments by U.S. President Donald Trump, who previously said he had halted plans for a broader military operation against Iran to allow diplomacy an opportunity to proceed.

Araqchi rejected that approach, saying diplomacy conducted under military pressure would not produce meaningful results.

“Diplomacy conducted through military threats is not effective or useful,” Araqchi said.

Trump had described prospective U.S.-Iran negotiations as a “last chance” to avoid a wider conflict. Iranian officials have not publicly responded to that characterization beyond reiterating that no direct negotiations are underway.

Oman Continues Mediating Strait of Hormuz Talks

While rejecting direct engagement with Washington, Iran confirmed that negotiations with Oman are continuing over a maritime arrangement designed to improve commercial shipping through the Strait of Hormuz.

According to the U.S. Energy Information Administration (EIA), approximately 20 million barrels per day, or roughly 20% of global petroleum liquids consumption, transited the Strait of Hormuz in 2024, making it the world’s most important oil transit chokepoint.

Reports indicate Oman is facilitating discussions aimed at restoring shipping confidence following months of regional tensions. Axios reported on Aug. 5 that the United States, Iran and Oman were nearing an interim understanding on reopening commercial navigation, although no agreement has been officially announced.

The Council on Foreign Relations reported that discussions include proposals related to Iran’s oversight of vessels entering the Persian Gulf through the strait. However, neither the United States nor regional maritime authorities have publicly confirmed acceptance of such an arrangement.

Maritime Security Remains Central to Regional Stability

The negotiations follow several security incidents affecting commercial shipping in the Gulf.

Iran previously targeted a vessel owned by the Abu Dhabi National Oil Company (ADNOC) during the broader regional conflict, raising concerns among shipping companies and energy markets over the security of one of the world’s busiest maritime corridors.

Any prolonged disruption in the Strait of Hormuz could affect global crude oil supplies because the waterway serves as the primary export route for producers including Saudi Arabia, Iraq, Kuwait, Qatar, the United Arab Emirates and Iran, according to the EIA.

The ongoing mediation by Oman reflects Muscat’s longstanding role as a neutral diplomatic intermediary between Tehran and Washington during periods of heightened regional tension.

Nuclear Oversight Remains a Major Sticking Point

Diplomatic tensions also extend to Iran’s nuclear program.

Iranian President Masoud Pezeshkian ordered the suspension of cooperation with the International Atomic Energy Agency (IAEA) following U.S. and Israeli strikes on Iranian nuclear facilities, reducing international inspectors’ access to Iran’s nuclear activities.

The suspension followed the United Nations Security Council’s decision to reimpose sanctions and restrictions related to Iran’s nuclear and missile programs, a move Tehran has rejected.

The IAEA has consistently stated that international inspections are central to independently verifying the peaceful nature of nuclear activities under global non-proliferation agreements.

Economic Pressure Continues Alongside Diplomatic Efforts

Economic pressure remains a key component of the broader dispute.

Reports indicate the U.S. Treasury Department revoked a waiver that previously permitted certain Iranian oil sales, although the reported action has not been independently confirmed through official Treasury documentation and therefore could not be fully verified.

The reported measure forms part of Washington’s broader sanctions strategy aimed at restricting Iran’s energy revenues while negotiations remain stalled.

Despite the continued deadlock over direct U.S.-Iran engagement, Oman‘s mediation on maritime security demonstrates that indirect diplomatic channels remain active. If negotiations produce a shipping arrangement acceptable to all parties, it could reduce regional tensions, improve confidence in global energy markets and create conditions for broader diplomatic engagement in the future.
