"Vienna Talks have been going on between Iran, P4+1 and the representative of EU, from the beginning and this path will continue unchanged until a result is reached," Shamkhani wrote in a tweet on Monday.
Negotiation with the US is not on the agenda of Iranian team because it will not be the source of any progress, he added.
The tweet comes as Iran and the P4+1 – China, France, Germany, Russia and the UK – are holding talks in Vienna with the indirect participation of the US to remove sanctions against Iran.
