TEHRAN (Tasnim) � Head of the Strategic Research Center of Iran's Expediency Council Ali Akbar Velayati underlined that the excessive demands of some Western states have hampered the progress of Iran's nuclear talks with six world powers.

Speaking in a meeting with President of China Institute of International Studies (CIIS) Qu Xing, Velayati touched upon the impediments to the progress of the ongoing negotiations between Iran and the Group 5+1 (Russia, China, the US, Britain, France and Germany) over Tehran's nuclear case.

"The Islamic Republic of Iran is making efforts to resolve the issues (related to the nuclear case) through dialogue but at the same time resists the excessive demands of certain Western countries," he noted.

Iran and the six powers are in talks to hammer out a lasting accord that would end more than a decade of impasse over Tehran's civilian nuclear program.

On April 2, the two sides reached a framework nuclear agreement in Lausanne, Switzerland, with both sides committed to push for a final deal until the end of June.

Velayati, who is also an adviser to the Supreme Leader of the Islamic Revolution, and the Chinese official also discussed Tehran-Beijing relations in diverse areas.

He paid an official visit to China to participate in a summit of the Conference on Interaction and Confidence-Building Measures in Asia (CICA) held in Beijing on May 25 and 26.

The Conference on Interaction and Confidence-Building Measures in Asia is an inter-governmental forum for enhancing cooperation towards promoting peace, security and stability in Asia. It is a forum based on the recognition that there is close link between peace, security and stability in Asia and in the rest of the world.

The idea of convening the CICA was first proposed by Kazakhstan President Nursultan Nazarbayev on October 5, 1992, at the 47th Session of the United Nations General Assembly.
