China News Service, March 1 (Reuters) - Washington is prepared to withdraw from efforts to revive the 2015 Iran nuclear deal if Iran shows no compromise, U.S. State Department spokesman Ned Price said on Feb. 28. .

  "If Iran is unwilling to compromise for progress in negotiations, we are ready to pull out," Price reportedly told reporters at a regular news conference about the indirect talks in Vienna.

  He added that the United States and its allies and partners would pursue "alternatives" if Iran was "unwilling to engage in good faith," without elaborating on those.

  White House spokesman Psaki said on the same day that Russia will still participate in the negotiations to resume the Iran nuclear deal, and the Biden administration hopes to make progress in the negotiations.

  In July 2015, Iran reached a comprehensive agreement on the Iranian nuclear issue with the United States, the United Kingdom, France, Russia, China and Germany.

In May 2018, the United States announced its unilateral withdrawal from the Iran nuclear deal, and subsequently restarted and added a series of sanctions against Iran.

Since May 2019, Iran has gradually suspended the implementation of some provisions of the Iran nuclear deal, but promised that the measures taken are "reversible".

  The parties involved in the Iran nuclear deal will start negotiations in Vienna in April 2021 to discuss the resumption of compliance between the United States and Iran.

On December 27, 2021, the eighth round of negotiations on the Iranian nuclear issue was launched in Vienna, the capital of Austria.
