A Qatari diplomatic effort to bridge differences between Washington and Tehran has produced a U.S. response to Iran’s proposed seven-day confidence-building arrangement, according to an official briefed on the negotiations.

Iranian Foreign Minister Abbas Araqchi received the American position through Qatari mediators in Doha on Tuesday. The official said the two sides are primarily divided over the timing and sequence of the proposed measures, rather than the measures themselves.

Araqchi is expected to consider Washington’s response after returning to Tehran on Wednesday, the official said.

The latest diplomatic exchange follows an Iranian proposal unveiled last week. Araqchi said at the time that Iran could allow the Strait of Hormuz to reopen and permit normal maritime traffic to resume if the required conditions were satisfied.

President Donald Trump subsequently rejected the Iranian proposal. Qatar then continued its mediation efforts in an attempt to narrow the differences between the United States and Iran.

According to the official, Qatari representatives presented Washington’s response on Monday after meeting with Araqchi and his delegation while they were returning from the United States.

The proposal under discussion envisions a seven-day period intended to establish enough confidence for Washington and Tehran to return to an expanded form of the memorandum of understanding reached in June. The framework would include concrete measures concerning Iran’s nuclear activities, although the official did not provide further details.

The official said the disagreement is focused on the order in which the proposed steps would occur, rather than disagreement over the individual elements contained in the plan.

Qatar has been acting as an intermediary between Washington and Tehran as efforts continue to end the conflict and secure the reopening of the Strait of Hormuz. The June memorandum helped produce a temporary ceasefire and dealt with both the strategic waterway and Iran’s nuclear program.

The new diplomatic activity follows Araqchi’s presentation of Iran’s seven-day proposal at the United Nations. His comments indicated that Tehran believes the necessary steps under the June framework are already known to Washington.

Qatar’s latest efforts represent another round of indirect diplomacy between Iran and the United States, with negotiations now focused on establishing the order and conditions under which the proposed measures would be implemented.
