Geneva, March 21 (IANS): Diplomats participating in the new round of talks on Iran's nuclear programme have showed strong political will and a pragmatic attitude, China's representative Wang Qun said.

This is the fifth round of negotiations since the P5 1 group, comprising the US, China, Russia, France, Britain and Germany, and Iran reached a decision to extend the negotiations on a comprehensive deal in November 2014, Xinhua reported.

Wang on Friday said that the week-long talks, which were suspended on Friday, made important advancement, though a plenary session of P5 1 countries and Iran failed to take place.

The parties held intensive multilateral and bilateral meetings, displaying strong political will, substantive attitude, as well as innovative thoughts and ideas in the crucial round of negotiations, Wang said.

"Negotiations are like rowing upstream, not to advance means backing off," Wang said, urging all sides to move forward to forge a final agreement.

"Without political determination, it is impossible to achieve a mutual-beneficial compulsory agreement," said Wang, who led the Chinese delegation and joined the negotiations on Wednesday.

China would like to work with other parties to clinch a comprehensive political agreement, he added.

The nuclear negotiations will be resumed in Lausanne next week.
