Negotiators from Iran and the P5+1 group of countries are set to resume a fresh round of talks on drafting the text of a final agreement over Tehran�s nuclear program in the Austrian capital of Vienna.

Iranian Deputy Foreign Minister for Legal and International Affairs Abbas Araqchi is expected to sit down�with top EU envoy Helga Schmid, who represents the P5+1 countries, in Vinenna later on Wednesday.

Iran�s Deputy Foreign Minister Majid Takht-e-Ravanchi and experts are also scheduled to join the talks.

According to Iranian diplomatic sources, the negotiations�will continue until Friday. Other diplomats, including the Chinese and Russian deputy foreign ministers, have indicated that the deputy foreign ministers of the P5+1 group will not join the meeting this week.

This will be the fourth round of talks between representatives of Iran and the six global powers just in one month after they ended their latest round of negotiations in Vienna on May 16.

Iran and the P5+1 countries � the US, France, Britain, China, Russia and Germany -- are seeking to finalize a comprehensive deal on Tehran�s nuclear program by the end of June. The two sides reached a mutual understanding in Lausanne, Switzerland, on April 2.

Takht-e-Ravanchi said on Monday that Iran seeks a "good" nuclear deal with the P5+1 countries, stressing, however, that Tehran will not cave in to any excessive demands by the opposite side.

Iran says the parameters agreed upon by the two sides in Lausanne constitute the basis for drafting a final deal.

�Iran will brook no excessive demands. The agreed parameters are those confirmed by the two sides in Lausanne and these parameters need to be stipulated in a written agreement by Iran and the P5+1,� Iranian Foreign Minister Mohammad Javad Zarif said on May 11.
