The hardline leader slammed Western powers for what he called hypocritical and dangerous policies that can only lead to nuclear proliferation, according to remarks broadcast on state-run Press TV.
He said the United Nations and the International Atomic Energy Agency were ineffective because they were dominated by a few nations.
"The Security Council has openly turned into a tool for the implementation of the policies of a few bullying nations," Ahmadinejad said in
This group should act in a way where all independent countries and governments could have a say and a role in running the affairs of that group," he said.
U.S. President Barack Obama has been pressing the Security Council to slap Iran with tougher sanctions for its nuclear ambitions. Iran says that its nuclear program is intended for civilian purposes.
Obama convened a 47-nation nuclear summit last week that focused on persuading Iran's reluctant trade partners like China to favor sanctions.
Ahmadinejad said he sent a letter to Obama earlier this week, telling his American counterpart that Iran was his only chance at success, the Islamic Republic News Agency reported.
The United States and its allies should abandon policies designed to dominate the oil-rich nations of the Middle East, Ahmadinejad said Saturday, adding that reliance on arms was a sign of a country without culture.
Iran, he added, is prepared to do all it can to counter nuclear weapons.
"One of the greatest treasons by those that monopolize nuclear weapons is to equalize nukes with nuclear energy," Ahmadinejad said. "The way to produce weapons is totally different than nuclear energy. And they know these very well, but they plan to talk about both these things in their own monopolized way. "
