Saeed Jalili warned the West over consequences of making past mistakes when dealing with Iran.
Speaking with al-Alam News Network, Jalili advised western countries not to make mistake in their calculations and do not take the same previous path.
Concerning possibility of western powers' resort to sanctions against Iran, he said, "any new sanction against Iran will bring more costs for the West."
"Today, we are in a very good condition, we advise them not to make mistake in their calculations and avoid the same previous paths. All of these ways are useless and costly," he added on Friday.
Iran, Turkey and Brazil inked a fuel proposal in Tehran last May based on which Iran was to send half of its uranium stockpile to Turkey to be sent to Russia and France for further enrichment. The West refused to accept the declaration.
The West and in particular the US accuses Iran of making nuclear weapons, Iran denies the allegation and insists that its enrichment program only seeks peaceful purposes including power generation and meeting the country's medical needs.
The UN Security Council has adopted three sets of sanctions against Iran following the country's refusal to freeze peaceful enrichment work.
The sanctions mainly target Iran's shipping industry, insurance, banking and energy sectors.
