Iran would prefer to negotiate with the "5+1" group in Turkey, Iranian Foreign Minister Manouchehr Mottaki said at a news conference in Singapore, the Fars news agency reported.
Previously, Mottaki said Iran's negotiations with the 'Six' could resume on Nov.10 or Nov.15 in Vienna, Istanbul or Geneva.
EU High Representative for Foreign Affairs and Security Policy Catherine Ashton in October invited Iran to hold talks in Vienna in mid-November. In response, Mottaki urged the EU to specify the timing of the negotiations. On Oct.16, the EU representatives proposed the period of Nov. 15-18.
The "5+1" group or so-called "Six" (the five permanent UN Security Council members plus Germany) has been seeking the suspension of Iran's uranium enrichment, which can pose a threat to nuclear nonproliferation regime since 2003.
