(FOX NEWS) — Iranian Foreign Minister Abbas Araghchi said Friday that Tehran has “no trust to Americans,” which is the “main obstacle in the way of any diplomatic effort.”

Speaking on the sidelines of a BRICS meeting in New Delhi, India, Araghchi said “After 40 days of war, when the U.S. became hopeless of achieving any goal in their aggression against Iran, they offered negotiations.”

“We are interested in negotiation, but only if the other side is serious,” he said. “We have no trust to Americans. This is a fact. And this is the main obstacle in the way of any diplomatic effort. I think all of you know that we have every reason not to trust Americans, while they have no reason not to trust us.”

“It is also suffering from contradictory messages we receive from Americans,” Araghchi also claimed. “Every day is different from the other day, from yesterday. A tweet today is different from yesterday’s tweet. Sometimes in one day we receive two different messages and this is the problem and adds to the question of mistrust.”

President Donald Trump said Friday that Iran’s latest peace offer didn’t have strong enough guarantees when it came to their nuclear program, and that it included an “unacceptable sentence.”
