TEHRAN (FNA)- Iranian President's Chief of Staff Mohammad Nahavandian underlined that termination of all sanctions should definitely be a part of any comprehensive agreement with the world powers.

"Any agreement (with world powers) depends on complete removal of all economic sanctions," Nahavandian said in a meeting with visiting Swiss economic delegation in Tehran on Wednesday.

Nahavandian pointed to Iran's unique economic advantages, and said, "Europe, including Switzerland, should use the present strategic opportunity to expand relations with Iran in different areas."

The Swiss economic delegation headed by Switzerland's former ambassador to Iran Livia Leu Agosti arrived in Tehran on April 26.

The former Swiss ambassador to Tehran, for her part, called for the further expansion of Iran-EU cooperation, specially in economic and political areas.

Representatives of famous Swiss firms and companies are present in the Swiss delegation that has met with senior Iranian trade and economic officials.

In relevant remarks last week, Iranian Deputy Foreign Minister and senior negotiator Seyed Abbas Araqchi underlined that all sanctions against the country would be terminated on the very same day that the final nuclear agreement between Tehran and the world powers would be put into effect.

Araqchi made the remarks after three days of negotiations with his counterparts from the Group 5+1 (the US, Russia, China, Britain and France plus Germany) in Vienna to draft a comprehensive deal.

In relevant remarks on April 9, Ayatollah Khamenei said that the underway talks between Tehran and the world powers were merely limited to the nuclear issue, and underlined that the sanctions against Iran should be annulled "on the same day (of the implementation) of any agreement" .

He specified conditions for a final nuclear deal with the world powers, and underlined that Iran doesn�t allow any inspection of its defensive and military centers.

"They (the foreigners) shouldn�t be allowed at all to penetrate into the country's security and defensive boundaries under the pretext of supervision, and the country's military officials are not permitted at all to allow the foreigners to cross these boundaries or stop the country's defensive development under the pretext of supervision and inspection," Ayatollah Khamenei said, addressing a large number of Iranian people in Tehran.
