Iran says it is limiting cooperation with the United Nations nuclear agency after the Security Council imposed new sanctions.
A government spokesman says Iran will reconsider when its case is returned to the International Atomic Energy Agency.
Iranian officials say the additional sanctions are illegal. Iranian Foreign Minister Manouchehr Mottaki says the new measures will not force his country to abandon nuclear development.
The sanctions approved Saturday ban all Iranian arms exports and freeze the assets abroad of 28 Iranian individuals and institutions believed to have ties to nuclear weapons.
The new sanctions also set a new 60-day deadline for Iran to comply with U.N. demands to stop enriching uranium. Failure to comply could result in further action against Tehran.
Meanwhile, European Union foreign policy chief Javier Solana said Sunday he hopes to revive negotiations with Iran on its nuclear program.
The United States and its allies accuse Iran of trying to develop nuclear weapons. Tehran denies the charge. Iran says its nuclear program is for peaceful purposes.
