Iran is not currently engaged in direct negotiations with the United States, while messages between the two sides are being exchanged through intermediaries, Iranian Foreign Minister Seyyed Abbas Araghchi said on Sunday.
In a statement, Araghchi said several countries were continuing efforts to create conditions for the resumption of negotiations between Tehran and Washington.
The Iranian Foreign Minister maintained that Tehran would not return to direct talks with the US until Washington ends its violations of the 14-point memorandum of understanding signed between the two sides in June.
Earlier on Saturday, Araghchi said the deal with Oman on a legal mechanism for managing traffic through the Strait of Hormuz is "very close".

Speaking at the Iranian President's press conference, Araghchi said: "Negotiations with Oman regarding the legal mechanism and management of the Strait of Hormuz for determining the route of traffic are underway, and we are very close to an agreement, but the opening of the Strait of Hormuz is subject to other conditions, including compensation for violations of the Islamabad Memorandum of Understanding by the United States."
"In the past, there was a TSS or route that the Islamic Republic considers no longer acceptable for ship traffic, and it is necessary to consider a new TSS, which, of course, has extensive technical and legal complexities," he added.
The statement comes as a US official stated on Friday that progress has been made in talks between Iran and Oman, which could lead to the reopening of the strategic Strait of Hormuz and restore oil exports disrupted by the five-month-old conflict.
"There is progress between Oman and Iran on the strait, and we expect a deal soon. Once the deal is announced to restore commercial shipping without impediments, the United States will lift the blockade of Iranian ports," an official said.
