"The Political Directors of the E3/EU+3 [P5+1] and Iran will meet again on 17 December 2014 in Geneva for a one-day meeting to continue diplomatic efforts towards reaching a long-term, comprehensive solution," the EU External Action Service said in press release.
The Iranian delegation is planning to hold a series of bilateral meetings ahead of the talks. Iran has also announced its intention to negotiate with the US delegation separately.
Iran has been repeatedly accused by Western countries of surreptitiously developing nuclear weapons. In light of suspicions about Tehran's uranium enrichment program, the UN Security Council, the European Union, the United States and a number of other countries have imposed several rounds of sanctions on Iran. Iranian officials have repeatedly denied the accusations, stating that the country's nuclear program is peaceful in nature and aimed at satisfying domestic energy needs.
