He said that the West made all its efforts to "stop Iran from turning into a nuclear country" but "they failed."
The Islamic republic has turned into a nuclear state and will continue its pace to take advantage of "peaceful nuclear energy program," the president emphasized.
Enemies have done their utmost to stop Iran's progress, he said, adding that, however, no one has been able to impose its will on the Iranian nation.
Ahmadinejad downplayed Western sanction pressures on the country's energy sector and economy, saying that "If you don't want to buy Iran's oil ..., we do not sell it to you and will run the country with non-oil revenues."
On Wednesday, Washington expanded sanctions on Iran by further tightening up economic measures against the Islamic republic and adding more names to its blacklist.
The Iranian president meanwhile praised the achievements of the Islamic revolution in a number of scientific and technological areas, and said that the country has made remarkable progresses during the past 34 years which have redeemed the country's " independence."
