Tehran, April 6 (IANS) Iran and the six world powers may start drafting the final agreement over Tehran’s nuclear programme from April 21, a senior Iranian nuclear negotiator said Sunday.

“We hope that in the upcoming talks we would be able to bring the views closer and narrow the differences regarding major issues, so we could get to the details…and start writing the text,” Press TV quoted Iranian Abbas Araqchi as saying Sunday.

The deputy foreign minister for legal and international affairs was speaking after a three-day meeting concluded in Vienna on nuclear programme with experts from Iran and the P5+1 group, namely Britain, China, France, Russia, the US plus Germany.

Hamid Ba’eedinejad, the head of Iran’s negotiating team, Saturday described the latest round of the nuclear negotiations, which was wrapped up earlier in the day, as “beneficial”.

Both sides have agreed to reconvene the next round of high-level talks in Vienna on May 7, in which they will continue to discuss tough issues, including Iran’s heavy water reactor.
