"They have this excuse that Iran is dodging negotiations while it is not the case," the Iranian leader was quoted as saying by state media.
"A person who has logic and has right on his side, why should (he) refrain from negotiations?" Ahmadinejad asked rhetorically.
He was implicitly responding to comments made by Western officials urging the Islamic republic to return to negotiations over its contested nuclear programme.
"The European Union stands together in sending that clear message to the government of Iran: that we wish to go back to negotiations, to invite them to pick up the issues which were left on the table in Istanbul a year ago," EU foreign policy chief Catherine Ashton said on Tuesday.
The last round of talks between Iran and the major powers consisting of Britain, China, France, Germany, Russia and the United States was held in Turkey in January 2011, but the negotiations collapsed.
The six powers are still waiting for Iran's reply to a letter Ashton sent in October, stressing that negotiations should focus on the "key question" of the Iranian nuclear issue, in order to remove doubts.
In Washington, State Department spokeswoman Victoria Nuland highlighted Thursday that the letter "very specifically offers talks if Iran is ready to be serious about coming clean with regard to its nuclear programme."
"So just saying you're open for talks doesn't meet the criteria that we have set, which is to be ready for talks and ready to be serious about letting the world know all of the details of your nuclear programme and proving your claims that it's for peaceful purposes."
The Islamic republic, which is already under four rounds of United Nations sanctions, vehemently denies its nuclear programme masks an atomic weapons drive as the West alleges, and insists it is for civilian purposes only.
Several Iranian officials have said publicly that Tehran was ready to resume talks, but without specifying the content of the talks, and have so far not formally responded to Ashton's letter.
"Iran is ready to negotiate on the basis of mutual respect," Iran's Foreign Minister Ali Akbar Salehi said on Wednesday.
He said he would forward the response from Iran's top nuclear negotiator, Saeed Jalili, "on the date and place of negotiations," to his Turkish counterpart Ahmet Davutoglu, who is acting as an intermediary, to be given to Ashton.
The European Union on Monday slapped an embargo on Iranian oil exports as the West ramped up pressure on Tehran over its controversial nuclear drive and urged it to return to the negotiating table.
In his televised comments, Ahmadinejad brushed off the effects of the newly imposed sanctions, saying they would not hurt his nation.
"Once our trade with Europe was around 90 percent but now it has reached 10 percent and we are not seeking this 10 percent... Experience has shown that the Iranian nation will not be hurt," Ahmadinejad said during a visit to the southern Kerman province.
"For the past 30 years, the Americans have not been buying oil from us. Our central bank has no relations with you," he added.
Iranian media reported on Thursday that parliament would consider a bill next week to ban oil exports to Europe following the bloc's decision to impose an embargo.
EU foreign ministers agreed on an immediate ban on oil imports and a phase-out of existing contracts up to July 1. They also froze the assets of Iran's central bank while ensuring legitimate trade under strict conditions.
The bloc imported some 600,000 barrels per day of Iranian oil in the first 10 months of last year, making it a key market alongside India and China, which has refused to bow to pressure from Washington to dry up Iran's oil revenues.
The new EU sanctions would make it even more difficult for Iran to be paid in foreign currency for its oil exports, which were worth more than $100 billion in 2011.

A great leader - no doubt. Though his country is in immense pressure from the West but he still beleives in negotiations without any assurance of trade or aid.
persians are clasic no doubt about it..
Iran's leaders know that sanctions bite. The supreme leader Ayatollah Khamenei might have his cost-benefit analysis that doesn't necessary be realistic. He wants to absorb the economic pain by sticking to his ambition of going nuclear. President Ahmadinejad is willing to negotiate. Unlike the supreme leader Ahmadinejad is loquacious und articulates bombastically. Yet among his word clouds, one can still figure out logical messages.
@Ahad
If Pakistan continues to allow terrorist to cross it's border to attack Iran or can't stop the murder of Pakistani Shia's you may get your wish. Of course once he is in charge you won't have to worry about blogging because he's not fond of "freedom of speech".
I wish he was our president
