U.S.-Iran MOU Implementation Talks Stall Over Format, Frozen Assets Dispute

Special envoy Steve Witkoff and senior adviser Jared Kushner traveled to Doha on Tuesday for consultations with Qatari mediators on the status of the June 17 memorandum of understanding between the United States and Iran, but the two sides offered conflicting accounts of what negotiations were actually scheduled, and Qatar confirmed that no direct U.S.-Iran meeting took place. Witkoff and Kushner met with Qatari Prime Minister Sheikh Mohammed bin Abdulrahman bin Jassim Al Thani, and Qatar's Foreign Ministry spokesperson said there was no meeting with Iranian officials. Qatar and Iran both stated there would be no high-level meeting between Washington and Tehran on Tuesday or in the coming days, directly contradicting a public announcement by President Trump.

The divergence on process reflects a deeper dispute over the substance of the MOU itself. White House press secretary Karoline Leavitt said on Fox News that Iran had requested a meeting and that Witkoff and Kushner would fly to Doha for "high-level meetings," with technical talks to follow "on the sidelines." Iran's chief negotiator, Kazem Gharibabadi, pushed back through state media, saying technical working group meetings had not been scheduled for the week, according to POLITICO [POLITICO]. Gharibabadi did not address the high-level meeting question. A White House official later clarified that U.S. and Iranian delegations were expected to participate separately the following day in technical talks with mediators from Qatar and Pakistan. Iran's Foreign Ministry spokesperson Esmaeil Baghaei confirmed that an Iranian delegation would be in Doha to engage with mediators on the interim peace agreement and the potential release of frozen Iranian assets, but that Iran had no plan to meet directly with the American delegation.

The MOU at the center of the dispute was signed June 17 by President Trump and Iranian President Masoud Pezeshkian, with Pakistan serving as a co-signatory mediator. The signing opened a 60-day window for direct negotiations on a final agreement to end the war. The framework sets out that 60-day ceasefire period during which further talks are expected to address unresolved issues, including Iran's nuclear program, uranium enrichment levels, and the status of its highly enriched uranium stockpiles. The MOU commits the United States to make fully available for use frozen or restricted funds and assets of the Islamic Republic of Iran upon the document's implementation. The MOU does not carry the force of a treaty under Article II of the U.S. Constitution and has not been submitted to the Senate for advice and consent. The MOU is a bilateral instrument between the United States and Iran; neither the other permanent members of the U.N. Security Council nor the European Union are parties to it.

The frozen-assets question presents a concrete near-term flashpoint. Iran's President Pezeshkian has said publicly that $6 billion in assets would be unfrozen as part of the MOU implementation, according to POLITICO [POLITICO]. Those funds trace back to a September 2023 prisoner swap negotiated by the Biden administration. The Biden administration agreed to unfreeze $6 billion in Iranian funds in exchange for the freedom of five wrongfully detained American citizens, granting clemency to five Iranians and issuing a blanket waiver for international banks to transfer $6 billion in Iranian oil sale proceeds, frozen in South Korea, to a bank in Qatar. Following the Oct. 7, 2023, Hamas attack on Israel, the U.S. and Qatari governments agreed to block Iran from accessing the funds, with Deputy Treasury Secretary Wally Adeyemo informing House Democrats of the arrangement. A U.S. official, granted anonymity to discuss sensitive negotiations, told POLITICO the assets "would be used to purchase American agricultural products to feed the Iranian people" and that any release would be conditioned on Iranian performance and implementation of the MOU [POLITICO].

The ceasefire itself remained fragile heading into the Doha meetings. After four days of trading strikes, both sides appeared to pause their attacks on Monday. The ceasefire agreement stipulates that Iran will make "arrangements using its best efforts" to ensure the safe passage of commercial vessels in the Strait of Hormuz, through which a fifth of the world's oil and liquefied natural gas supplies travel. The MOU specifies "no charge" for commercial vessels passing through the strait, but only for 60 days, and leaves the "future administration" of the strait to be worked out by Iran, Oman, and other Gulf states, keeping the question of future tolling open. The legal authority under which the Treasury Department would issue sanctions waivers to implement the asset-release provisions flows from the International Emergency Economic Powers Act, which grants the executive branch broad discretion to license or block transactions involving a declared national emergency, subject to congressional notification requirements under 50 U.S.C. § 1703.

Secretary of State Marco Rubio and Witkoff briefed all members of Congress on the Iran talks in an afternoon conference call on Tuesday, according to POLITICO [POLITICO]. The briefing is consistent with informal executive branch practice of providing congressional notifications on sensitive diplomatic developments, though it does not constitute the formal report required under the National Security Act or the Case-Zablocki Act, which mandates submission of international agreements to Congress within 60 days of their entry into force. The MOU represents the most significant diplomatic development of the conflict and, rather than setting out a temporary cessation of hostilities alone, establishes a framework for negotiations that could substantially reshape the regional economic landscape. Whether the 60-day negotiating clock continues to run, or the ceasefire collapses before a final deal is reached, may turn on whether the two sides can agree on what kind of talks are even taking place.
