The secretary of Iran's Supreme National Security Council has said that any wrong measure by the six major powers will negatively affect future talks over the country’s nuclear program.

SNSC secretary general made the remarks at a press conference in Moscow late on Tuesday after two days of talks between Tehran and the 5+1 group (the five permanent members of the UN Security Council and Germany) when asked if the group had agreed to help lift the sanctions imposed on Iran.

The negotiations in Moscow were a continuation of talks that were held in Istanbul on April 14 and in Baghdad on May 23 and 24.

EU foreign policy chief Catherine Ashton represented world powers in the talks and Jalili led the Iranian delegation.

During the talks in Moscow, the two sides agreed to hold expert meetings in Istanbul on July 3.

Commenting on the sanctions that have been imposed on the country, Jalili said that Iran's rights must be respected and measures against the country must be dropped to help enhance confidence.

Asked if the oil embargo that the European Union has imposed on Iran, which will take effect on July 1, would affect future talks, Iran's chief nuclear negotiator said, 'We have emphasized that negotiations should be pursued with a cooperative approach, and any measure taken against this approach will definitely affect the outcome of the negotiations. And any wrong move on a path other than the path of cooperation will definitely not be constructive and will be properly responded to.'
