New York, Sep 27 (IANS): Iran and the P5 1 group have concluded the seventh round of nuclear talks in New York and have agreed to meet again.

"All parties agree to hold the next round of talks as soon as possible," chief negotiator of the Chinese delegation, Wang Min, said Friday.

According to Wang, during the talks all parties demonstrated the political will to reach a comprehensive agreement at an earlier date and carried out negotiations over the core issues including Iran's uranium enrichment, Xinhua reported.

This round of negotiation between Iran and the the P5 1 group - the US, Russia, China, France and Britain plus Germany - started a week ago.

On Thursday night, Iranian Foreign Minister Mohammad Javad Zarif, European Union (EU) foreign policy chief Catherine Ashton and US Secretary of State John Kerry held a meeting in New York to discuss progress made during the ongoing nuclear talks and to confer on how to proceed with the negotiations.

Zarif leads the Iranian negotiating team while Ashton heads the opposition side.

Wang believed the talks for achieving a comprehensive agreement have reached the final crucial stage and hoped all parties can focus on the core issues and creatively seek a solution of mutual benefit.

The two sides clinched an interim deal in Geneva, Switzerland, last November.

The agreement took effect Jan 20 and expired six months later. In July, they agreed to extend the negotiations until Nov 24 amid differences over a number of key issues.
