TEHRAN (Mehr News Agency) -- The secretary of Iran’s Supreme National Security Council (SNSC), Hasan Rowhani, returned to Tehran on Tuesday night from Brussels, Belgium, where he had been attending meetings with European Union officials since Sunday.

Rowhani arrived in Tehran at 10:55 p.m. local time Tuesday night.

The SNSC secretary met with EU foreign policy chief Javier Solana and EU External Relations Commissioner Chris Patten as well as the foreign ministers of Britain, Germany, France, and Belgium on the sidelines of the monthly session of EU foreign ministers on Monday.

Rowhani’s trip to the European Union headquarters on the threshold of the International Atomic Energy Agency (IAEA) Board of Governors meeting is seen as an effort to remind the EU countries about their commitment to the Tehran Declaration, which was signed in October.

According to the Tehran Declaration, Iran agreed to sign the additional protocol to the nuclear Non-Proliferation Treaty (NPT) and EU member states Britain, France, and Germany committed themselves to take up Iran's case at the IAEA Board of Governors meeting if IAEA Director General Mohamed ElBaradei released a positive report on Iran’s nuclear activities.

The nuclear policy which Iran recently adopted was so sensible that the EU ministers agreed to sign the Tehran Declaration, Solana told Rowhani, stressing that Iran had been honest about its nuclear program and that the case should not be referred to the United Nations Security Council, which could impose sanctions.

After meeting the Italian, French, and British foreign ministers as well as a high-ranking German official, Rowhani called the Iran-EU agreement for the implementation of the Tehran Declaration a good basis for bilateral confidence and a starting point for regional and international cooperation between the two sides. Speaking to reporters in Brussels, Rowhani said, “We are not worried at all because there is no rational reason to refer Iran’s peaceful nuclear activities to the UN Security Council."
