The senior Iranian official said the path ahead is very complicated and there are many vacillations to be found.
Iran should exercise patience, vigilance and wisdom as it holds nuclear negotiations with the Six Majors, Salehi stated, adding that the 2 sides of the talks have taken good steps in negotiations and the process is expected to continue.
Salehi said earlier the week that technical talks had been blocked and he was assigned to join nuclear talks to provide more explanations in details.
Luckily, the last 2 rounds of talks were fruitful and the two sides took major strides to remove misunderstanding, he asserted.
However, he stated that it is not possible to reveal details of recent nuclear talks.
The two sides discussed uranium enrichment at Arak research center, research and development program, issues pertaining to Fordo nuclear site and some minor cases, he said.
He added: In general, talks were balanced; I believe that because of the scientific knowledge and experience in the field, my presence was very helpful trying to break the deadlock over technical issues of the Iranian nuclear program.
