VIENNA, April 09. /ITAR-TASS/. The second final day of talks between Iran and the P5+1 negotiators (five permanent members of the UN Security Council and Germany) will be held in the Austrian capital on Wednesday. Negotiating parties will participate in talks in broader delegations, since talks became much more detailed as compared with previous rounds of negotiations.

The negotiators decided to focus on issues that had not been discussed in detail yet, spokesperson of the EU foreign policy chief Michael Mann said on Tuesday. In March, the interlocutors succeeded to find preliminary solutions on four of nine packages of issues, particularly uranium enrichment, operation of the heavy research reactor in Arak, international nuclear co-operation and lifting the pressure of sanctions against Iran.

This time talks will focus on narrowing the gap on such issues as verification procedures regarding Iranian nuclear program, its transparency and the most complicated issue of possible military component of Tehran's nuclear research.

In the words of Mann, it is still early to say that agreements begin to take some shape.

However, Iranian diplomats and P5+1 negotiators expected that current round of talks would be final preparatory round and already at a next meeting that was due in May negotiating parties would begin to sign provisions of a future comprehensive agreement.

“For beginning we should clarify views of each other on all current issues,” Iranian Foreign Minister Mohammad Javad Zarif said, adding that it was planned to begin drafting of a treaty in May.

Already now Tehran decided to begin preparations to legal formulation of agreements with the P5+1 group of negotiators. “A hard and difficult work is in store for us to draft and fix a final agreement,” an official of Iranian delegation told ITAR-TASS, noting that “With this in view it was decided to attract well-known lawyers specialized in international law in the process.”

Several experts have voiced concerns earlier that the atmosphere inside the P5+1 negotiating countries might be “spoiled” at current round of talks over external reasons, putting it precisely, disagreements on Ukrainian crisis. By all appearance, the negotiators succeeded to avoid this.
