(IRNA) - Secretary of Iran's Supreme National Security Council (SNSC) Ali Larijani told reporters before leaving for Iran Sunday that his talks with EU foreign policy chief Javier Solana on the nuclear issue had been "constructive," adding that the talks will continue this weekend, reports Trend.
Larijani held two rounds of talks with Solana over the weekend lasting for seven hours.
He said his talks with Solana were necessary because Iran's response to the incentives package offered by the six powers needed to be explained to remove certain ambiguities.
He said that during his talks in Vienna with European officials progress had been made and some ambiguities cleared and that they also agreed with him on certain principles.
He said the process now underway shows there are points of common understanding which can help solve the current problem.
He also said that if the parties are able to agree on certain principles based on the NPT, any problem can be worked out.
The Iran nuclear issue is not a complicated one, but there are some ambiguities and misunderstandings which should be addressed, he added.
Larijani, who also held talks with IAEA chief Mohamed El-Baradei in Vienna, said the talks were necessary, adding that Iran should maintain constant contact with the agency as the main source of reference on nuclear issues.
