Iranian foreign minister abdullahiyan said on the 15th that in order to successfully complete the negotiations between the parties concerned of the comprehensive agreement on the Iranian nuclear issue, the United States should make the necessary response, and the "ball" is on the United States side. After concluding his visit to Russia on the same day, abdullahiyan wrote on social media that he had a "fruitful meeting" with Russian Foreign Minister Lavrov on bilateral relations, Iran nuclear negotiations and other issues. He is convinced that Russia still supports the final agreement reached in the Iranian nuclear negotiations held in Vienna, the capital of Austria. Abdullahiyan said that in order to successfully complete the Iranian nuclear negotiations, the United States should make the necessary response, and the "ball" is on the United States side. 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 Iran 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". The relevant parties to the Iran nuclear agreement began to hold negotiations in Vienna in April 2021 to discuss the resumption of performance by the United States and Iran, and the United States indirectly participated in the negotiations. The eighth round of negotiations was launched in Vienna on December 27, 2021. On March 11 this year, the EU high representative for foreign and security policy Borrell announced that the negotiations were suspended due to "external factors". (Xinhua News Agency)
