Upcoming talks between Iran, IAEA could hardly produce concrete progress: diplomats VIENNA, May 13 (Xinhua) -- Vienna-based diplomats on Monday expressed low expectations over the upcoming talk between Iran and the UN nuclear watch dog this week. "Our expectation is still low, there is no indication that Iran would make any substantial deal with IAEA," a Vienna-based western diplomat told Xinhua on Monday. Another diplomat said the prospect of the talks remain dim. "It's difficult for Iran to accept the agency's demand, which is already beyond the (IAEA) 'Safeguards Agreements'," the Vienna based diplomat told Xinhua. Iran and IAEA are expected to resume talk on Wednesday in Vienna, trying to strike a deal on the nuclear inspection frame work, so called "structured approach," which is set to conduct nuclear inspection in Iran beyond "Safeguards Agreements" to clarify so called "possible milliary dimension" of Iranian nuclear program.
