Speaking to reporters, Manouchehr Mottaki said, "Iran implements its civilian nuclear program based on its legitimate rights, and does not pursue any activity that would go beyond provisions of the IAEA [International Atomic Energy Agency] and the NPT [Nuclear Non-Proliferation Treaty]."
The comment came in response to Western media reports that Iran had allegedly applied to the UN nuclear watchdog for permission to launch a heavy water plant in Araq.
Mottaki said Tehran keeps the IAEA informed about its activities at the Araq site as well as at other nuclear facilities.
Western governments suspect the Islamic republic of seeking to obtain a nuclear bomb, and have been pushing for it to stop uranium enrichment and other related activities.
The UN Security Council is now considering an EU-sponsored draft resolution that would ban the supply of nuclear and missile technology to Iran.
Russia, a veto-wielding Council member which has consistently supported Iran's drive for nuclear fuel and is building a $1 billion power plant in the country, has refused to support the proposed European sanctions as excessive. The United States, by contrast, has said they are not tough enough.
