Deep Tide TechFlow News, April 13 — On the 13th, Iran's Ministry of Foreign Affairs stated that the United States kept changing its demands during negotiations with Iran in Islamabad, which is the reason why both sides failed to reach an agreement. The Iranian Foreign Ministry said that on the evening of the 12th, Iranian Foreign Minister Araghchi told French Foreign Minister Barron in a phone call that although Iran "completely distrusts" the U.S., it still participates in negotiations with a responsible and good-faith attitude and has made progress on multiple issues. However, due to the U.S. making excessive demands and constantly changing its requests, an agreement was ultimately not reached. (Xinhua News Agency)
