TEHRAN, Sept. 11 (Xinhuanet) -- Iran refused to fully suspend its nuclear activities in Isfahan nuclear plant and threatened not to go into negotiations with the EU if preconditions are set, its foreign minister said Sunday.

    Speaking at a news conference, Iranian Foreign Minister Manuchehr Mottaki termed re-suspending Iran's nuclear activities as "out of the question".

    "Iran will not accept any precondition set for the continuation of nuclear negotiations, and we will never suspend nuclear activities at the Isfahan uranium conversion facility again," Mottaki said at his first press conference as foreign minister.

    Mottaki said although the nuclear talks between Iran and the European Union (EU) are still underway, Iran will just continue the negotiations which can recognize its legal rights on peaceful nuclear technology.

    The nuclear negotiations between the Islamic republic and the EU, represented by the big three of Britain, France and Germany, were stalled after Tehran resumed in August the uranium conversion activities in the central city Isfahan, a preliminary step toward uranium enrichment.

    This move triggered outcry from the EU, which urged Iran to re-suspend the conversion activities before Sept. 19, when the International Atomic Energy Agency (IAEA) board of governors will gather to discuss this issue.

    The EU also warned that a defy of the deadline will prompt the UN nuclear watchdog to refer Iran's case to the UN Security Council.

    However, Mottaki brushed aside the threat at the news conference.

    Iran will not deterred by a referral to the UN Security Council,he said, adding such a referral will incur "consequences".

    "There is no legal base for the referral. The threat has been political motivated," Mottaki said, stressing that Iran has been reasonably cooperating with the IAEA to remove the suspicion over its intention of nuclear program.

    Mottaki, a former conservative lawmaker, was appointed as foreign minister by President Mahmoud Ahmadinejad in mid-August, and successfully received Majlis's (parliament) approval on Aug. 24.

    The EU, as the longtime broker of the Iranian nuclear case, has been trying but in vain to persuade Iran to abandon its efforts to build nuclear reactor cycles, including uranium enrichment.

    The United States accuses Iran of developing nuclear weapons under the disguise of civil usage, a charge rejected by Tehran. Enditem
