Iran was overwhelmingly defeated by Japan in a vote on Friday for an Asian seat on the 15-seat Council. Tokyo secured a crushing 158-32 votes from the 192-member assembly for the right to sit on the Council for two years starting in January.
"Obviously the structure of the Security Council is such that it must be said in practice a few special countries make decisions there and impose ideas," Iran's U.N. ambassador, Mohammad Khazaee, told state television.
"And it is natural that these countries are disinterested in independent ideas or the entry of states that believe in the necessity of re-examining its structure," he said.
"Anyhow, some do not have the tolerance to hear an independent voice in a structure incompatible with today's world necessities," he added.
Iran's delegation did not speak to reporters immediately after the vote in New York.
Iranian President Mahmoud Ahmadinejad, who regularly rails against the West, has repeatedly said the Security Council was a relic of a post-World War II order that needs updating.
He has also repeatedly refused to halt sensitive nuclear work as demanded by the Council. The West believes Iran is seeking to build atomic bombs, a charge Tehran denies saying its plans are peaceful and aimed at generating electricity.
