Iran is competing against Kuwait to be the rapporteur of the UN General Assembly's First Committee for its 68th session, which begins in October, Reuters quoted UN diplomats as saying on Tuesday.
The rapporteur reports on the proceedings of the 193-member committee.
A spokesman for Iran's UN mission confirmed the country's bid on Tuesday. Asked why Tehran was interested in the position, he said: "It's a normal routine by a member state."
The First Committee considers all disarmament and international security matters, cooperation in the maintenance of international peace and security, as well as principles governing disarmament and the regulation of armaments.
Earlier this month Iran withdrew its candidacy for the UN Human Rights Council without explanation.
