The International Atomic Energy Agency (IAEA) in a statement announced February 21 to 22 as the date for talks with Tehran officials, FNA reported.
The International Atomic Energy Agency said that it was committed to 'intensifying dialogue'.
Earlier, Deputy Director-General of the IAEA Herman Nackaerts had said at Vienna airport upon arrival from a visit to Iran that the UN nuclear watchdog is due to send another delegation to Iran in the near future.
"But of course there is still a lot of work to be done, and so we have planned another trip in the very near future," Nackaerts said, following his visit to Iran to discuss Tehran's nuclear program.
The deputy director-general of the UN nuclear agency also said that both sides are "committed" to resolving all outstanding issues.
"We had three days of intensive discussions about all our priorities. We are committed to resolving all the outstanding issues and the Iranians said they are committed too," he said at Vienna airport on Wednesday.
IAEA's high-ranking delegation, led by Nackaerts and Assistant Director General for Policy Rafael Grossi, arrived in Tehran on Sunday to hold talks with Iranian officials regarding Iran's nuclear program.
"We had a good trip ... I will now go back to headquarters and inform the DG [IAEA director general Yukiya Amano] about the mission," he said.
The visit came at the invitation of the Atomic Energy Organization of Iran (AEOI).
Nackaerts had earlier told reporters as he was about to depart from Vienna airport that the team will try to resolve all the outstanding issues with Iran.
Iran's Ambassador to the IAEA Ali Asqar Soltaniyeh said on Friday that the main objective is to "thwart plots by enemies who are leveling unfounded allegations" against Iran and to prove that the country's nuclear program is transparent.
Soltaniyeh said the visit is aimed at negotiating issues of common interest between Tehran and the agency.
Washington and its Western allies accuse Iran of trying to develop nuclear weapons under the cover of a civilian nuclear program, while they have never presented any corroborative evidence to substantiate their allegations. Iran denies the charges and insists that its nuclear program is for peaceful purposes only.
Tehran stresses that the country has always pursued a civilian path to provide power to the growing number of Iranian population, whose fossil fuel would eventually run dry.
