Iranian Foreign Minister Hossein Amir Abdullahian said Thursday that "political interference" in the technical affairs of the International Atomic Energy Agency (IAEA) is "unconstructed."
Abdullahian made the comments during a telephone conversation with his Singaporean counterpart Vivian Balakrishnan, where they spoke about the upcoming meeting of the IAEA Board of Governors.
Abdullahian added that his country's technical "cooperation" with the IAEA and the international organization's "repeated emphasis on the peaceful nature" of Iran's nuclear program "cannot be shown in reverse from a hasty point of view," he said.
"All parties need to remain committed to diplomacy and not resort to threats."

On Wednesday, Iran warned that it would respond to any "unconscionable step" the IAEA Board of Governors might take next week.
The Iranian foreign ministry's position came at a time when a European diplomatic source confirmed that Washington, London, Paris and Berlin had prepared a draft resolution calling on Tehran to cooperate with the IAEA, which is likely to be presented to the council, which begins its meetings from Monday.
The source told AFP in Vienna that these countries have presented to the other members "a draft resolution calling on Iran to cooperate on the issue of undeclared sites," noting that if agreed on it "we will present it on Monday to be approved in the middle of the week."
In a report last Monday, the UN agency said Tehran had not provided sufficient clarification on traces of nuclear material found at three sites that Iran had not previously stated had witnessed such activities, namely Marwan, Ramin and Torruzabad.
The case dates back years, and the two sides agreed on a road map to seek to clarify questions during Grossi's visit to Tehran in March.
Iran's foreign ministry responded to the report on Tuesday, saying it was "unfair."
Resolving this issue is seen as central to efforts to revive the nuclear deal between Tehran and major powers, from which the United States withdrew in 2018.
Iran's enriched uranium stockpile has more than 18 times exceeded the limit under the 2015 nuclear deal between Tehran and major powers, the IAEA said in a separate report Monday.The reports came at a time when talks aimed at reviving the nuclear deal have been stalled for weeks.
