During his stay in China, Ahmadinejad would only participate in activities related to the Shanghai World Expo, Qin said.

Responding to a question on the Iranian nuclear issue, Qin reaffirmed that China always adhered to the dual-track strategy for resolving the issue, and always insisted that dialogue and negotiations should be the best way to resolve the issue.

China hoped Iran would strengthen cooperation with the International Atomic Energy Agency (IAEA) to resolve the issue, Qin said.

He also called on the parties concerned to promote the proper settlement of the Iranian nuclear issue through dialogue, negotiations and diplomatic efforts.
