VIENNA, July 13 -- Chinese Foreign Minster Wang Yi on Monday called on related parties to end the marathon negotiations on an Iranian nuclear deal, saying conditions are ripe for a good deal and that an agreement could be reached anytime in Vienna.

"China believes no agreement could be perfect,......Conditions are already in place for us to reach a good agreement," Wang told reporters. "We believe that there can not and should not be a further delay of the negotiations."

Wang was scheduled to meet on Monday his Iranian counterpart Mohammad Javad Zarif as well as foreign ministers from the other countries of the P5 plus 1 group that includes Britain, China, France, Germany, Russia and the United States.

Zarif said on Sunday that there could be no further extension of the talks, but there was still a lot of work to be done.

After over two weeks of bargaining, Iran and the six world powers are heading toward a deal to end the decade-old standoff on Iran's nuclear program.

Over the past 18 months, the negotiating parties have resolved many of the tough issues in what has been seen as an impossible task, such as capping Iran's nuclear capacity and assuring the transparency of Tehran's atomic plan.

Western states seek to bar Iran from getting a nuclear bomb with a comprehensive deal while Tehran wants a relief of sanctions from the West which have seriously hammered the country's economy.
