VIENNA, October 15 (RIA Novosti) — A trilateral meeting involving Iranian Foreign Minister Javad Zarif, EU Foreign Policy Chief Catherine Ashton and US Secretary of State John Kerry has started at the Palais Coburg in Vienna.
The sides are expected to bridge the remaining differences to facilitate the signing of the comprehensive nuclear agreement before the November 24 deadline.
Prior to the trilateral talks Zarif and Ashton held a bilateral meeting. Following the meeting with the EU foreign policy chief on Tuesday, Iran's top negotiator said the remaining differences could be resolved.
"There are outstanding differences, but it doesn't mean that these differences cannot be resolved," Fars news agency quoted Zarif as saying.
Zarif also reiterated that Tehran's nuclear program is peaceful, thus striking a comprehensive agreement is omnipotent, but all the sides should agree on all the issues.
The volume of uranium enrichment and the lifting of EU, US and UN nuclear-related sanctions remain key issues on the talks agenda.
