PANews reported on April 11 that, according to Cailian Press, Iranian Parliament Speaker Qassem Ghalibaf stated in Islamabad, the capital of Pakistan, early on the 11th local time that Iran is sincere in negotiating with the United States, but does not trust the US because previous negotiations between the two sides "always ended in failure and betrayal."
