Iran's Deputy Foreign Minister: Iran's nuclear negotiations are trying to make "positive progress". According to the news agency of the Islamic Republic of Iran, bageri told reporters in the Austrian capital Vienna on the same day that since the beginning of the eighth round of U.S. - Iran resumption of compliance negotiations, all parties have made efforts to achieve results. The key to the success of the negotiations is to reach an agreement on the effective lifting of sanctions against Iraq. If the "other party" can show sincerity in lifting sanctions against Iran and accept the mechanism proposed by Iran on verification and assurance that it will not withdraw from the agreement, it is possible to reach an agreement "in a shorter time".

In July 2015, Iran reached an Iran nuclear agreement with the United States, Britain, France, Russia, China and Germany. In May 2018, the US government unilaterally withdrew from the Iranian nuclear agreement, and then restarted and added a series of sanctions against Iraq. Since May 2019, Iran has gradually suspended the implementation of some provisions of the Iran nuclear agreement, but promised that the measures taken are "reversible".

Relevant parties to the Iran nuclear agreement began to hold talks in Vienna in April 2021 to discuss the resumption of compliance between the United States and Iran. The eighth round of negotiations was launched in Vienna on December 27, 2021.
