The 1955 Treaty of Amity established economic relations and consular rights between Tehran and Washington. On October 3, the International Court of Justice ordered Washington to lift sanctions it had imposed back in May targeting humanitarian trade, food, medicine, and civil aviation.
"As you know, the court (the ICJ) is the most important legal pillar of the United Nations, and all countries should observe its rulings in line with the UN Charter," Khoshrou said.
He reiterated that the US, which hosts the UN on its soil and is a permanent member of the UN Security Council, practically disregards the court’s rulings and even issues threats.
"What is worse is that the US has said it does not credit any ruling issued by the court or any litigation at the tribunal in the future, considering it incompetent in whatever legal proceedings," Khoshrou added.
Khoshrou's remarks came a day after ICJ Judge Abdulqawi Ahmed Yusuf detailed the restraining order facing Washington in a report to the UN General Assembly.
The US started imposing bans on Iran after unilaterally leaving the Joint Comprehensive Plan of Action (JCPOA) on May 8. The JCPOA is a multilateral nuclear treaty which was reached between Tehran and the world powers, including the US, in Vienna on July 14, 2015.
