TEHRAN, May 25 (Xinhua) -- If Iran and the world powers do not reach an agreement for a comprehensive nuclear deal before July 20, it will make the work "more difficult," Iran's senior nuclear negotiator Abbas Araqchi said here on Sunday.
"Although the negotiations can be continued for another six months, I believe the longer the talks, the more advantageous it will be for those opposing the (interim) Geneva deal" which ends on July 20, the official IRNA news agency cited Araqchi as saying.
The foreign forces who are against the Geneva deal are seeking to create tension in the region and do not want a final deal in the nuclear talks between Iran and the P5+1 group -- Britain, China, France, Russia, the United States plus Germany, he said.
The Iranian official dismissed comments that the recent negotiations with the world powers have failed or reached a deadlock. "Although we have not achieved a tangible progress, it is something natural and the negotiations will continue," Press TV quoted him as saying.
"In the course of the negotiations we seek to establish Iran's peaceful nuclear program, including uranium enrichment, and eliminate excuses for exerting more pressures on Iran," said Araqchi, who is also Iran's deputy foreign minister.
In return, "what we will accept to do is some confidence- building measures and a response to some ambiguities to ensure that Iran's nuclear program does not have nuclear dimensions," he added.
"If we pursue our peaceful nuclear program, including uranium enrichment activities, and sanctions against us are removed is a win for us," he said, adding that "to make sure that there is no weapon program in Iran's nuclear program is also a win for them ( the powers)."
The fourth round of Iranian nuclear talks ended in Vienna on May 16 with no agreement reached as differences remained on such issues as Iran's nuclear fuel fabrication capability, transparency of its nuclear plan as well as its ballistic missile program.
Western countries accuse Iran of secretly developing nuclear weapons and demand that Iran significantly scale back its nuclear program and subject it to more transparency.
However, Tehran insists that it has the right to develop peaceful nuclear programs under the Non-Proliferation Treaty (NPT) and that its nuclear activity is for peaceful purposes only. The next round of talks will happen on June 16-20.
