Mohammad-Ali Hosseini said four rounds of negotiations between the European Union foreign policy chief, Javier Solana, and Tehran's chief nuclear negotiator Ali Larijani in Brussels and Berlin had brought positive results and Iran hoped to make future progress in the talks on the Iranian nuclear program.
The six powers mediating the Iran nuclear issue, the five permanent UN Security Council members plus Germany, have been trying to persuade Iran to accept a package of incentives, and suspend uranium enrichment, which many countries believe is the beginning of an Iranian nuclear weapons program.
But the Iranian diplomat reiterated that the proposed unilateral moratorium on uranium enrichment by Iran was absolutely unacceptable.
On October 1 President George W. Bush signed the Iran Freedom Support Act, stipulating sanctions against countries that maintain energy cooperation with Iran and supply weapons to the country.
Iran's President Mahmoud Ahmadinejad said Thursday that no sanctions would stop Iran from enriching uranium, a necessary step to creating a nuclear fission bomb.
