Elahian said on Wednesday the West has recognized the fact that threats and sanctions against the Islamic Republic are not helpful and have in fact “opposite effects.”

The West has no option but to engage in diplomacy with Iran; the Baghdad talks, therefore, would be a litmus test for the P5+1 group - comprising Britain, China, France, Russia, the United States and Germany, she pointed out.

"One should wait and see whether it (the P5+1) is after confidence building and positive and constructive interaction or after pushing the talks into a stalemate," Elahian underscored.

The Iranian lawmaker also said Tehran expects the Baghdad talks to be held in the same ambience as in the Istanbul meeting, which would be positive for the continuation of the talks.
