China believes dialogue and negotiations are the proper way to handle the Iranian nuclear issue, a Foreign Ministry spokesman said Thursday.

Spokesman Liu Weimin announced Thursday that the deputy secretary of Iran's Supreme National Security Council Ali Baqeri paid a working visit to China on Tuesday.

Assistant Foreign Minister Ma Zhaoxu held talks with Baqeri during his visit, and they exchanged views on the Iranian nuclear issue and other international and regional issues of common concern, Liu said.

Dialogue among Britain, China, France, Russia, the United States, Germany and Iran has seen positive momentum, Liu said, adding China hopes each side can cooperate sincerely and make more efforts to solve the issue peacefully on the basis of previous agreements.

Liu said China will continue to play a constructive role in resolving the issue.
