伊朗外交部发言人埃斯梅尔·巴盖伊周二表示，与美国可能达成的协议谈判没有新进展。
Iran's Foreign Ministry spokesman Esmaeil Baqaei said Tuesday that there was no new development on a possible deal with the US.
巴盖伊对官方媒体表示，不过，与华盛顿的讨论正通过调解人继续进行。
Discussions with Washington, however, are continuing via mediators, Baqaei told state media.
他说：“以往的经历阻碍了对美国外交诚意的任何乐观预期。”并补充称，德黑兰为应对敌对行动可能重演而做的自卫准备“处于最高水平。”在美以于2月28日对伊朗发动袭击后，中东局势依然紧张。德黑兰通过打击该地区的以色列和美国目标进行了报复，随后于4月达成停火协议。
"Previous experiences block any optimism about America's seriousness in diplomacy," he said, adding that Tehran's preparations to defend itself in case of renewed hostilities were "at the highest level." Tensions in the Middle East have remained high after the US and Israel launched attacks against Iran on Feb. 28. Tehran retaliated by targeting Israel and US assets in the region before a ceasefire agreement was reached in April.
华盛顿和德黑兰于6月18日签署了关于霍尔木兹海峡航行自由的谅解备忘录，但因在水道安全问题上存在分歧，其实施陷入停滞。
Washington and Tehran signed a memorandum of understanding on freedom of navigation in the Strait of Hormuz on June 18, but its implementation stalled because of disagreements concerning security in the waterway.
