TEHRAN, 1 March, 2020, (TON):  The European Union's political chief recently proposed the casual gathering including all gatherings of the Vienna bargain, a recommendation acknowledged by US President Joe Biden's organization.

Following Biden's political race, the US, the European gatherings to the arrangement - France, Germany and Britain - and Tehran have been attempting to rescue the understanding, which conceded Iran global approvals help as a trade-off for limitations on its atomic program.

The understanding has been approaching breakdown since previous president Donald Trump singularly pulled out in 2018 and strengthens devastating approvals as a component of a "greatest pressing factor" crusade against Tehran.

"Considering the recent positions and actions of the United States and the three European countries, (Iran) does not consider the time suitable to hold the informal meeting proposed by the European coordinator," foreign ministry spokesman Saeed Khatibzadeh said in a statement.

"There has still been no change in the US positions and behavior yet," he added, saying the Biden administration has continued "Trump’s failed policy of maximum pressure".

Biden has flagged preparation to resuscitate the arrangement, yet demands Iran first re-visitation of all its atomic responsibilities, the majority of which it suspended in light of the assents, while Tehran requests Washington venture out rejecting the authorizations.

"While we are disappointed at Iran’s response, we remain ready to reengage in meaningful diplomacy to achieve a mutual return to compliance," a White House spokesperson said on Sunday.

"We will be consulting with our P5+1 partners on the best way forward," the representative added, alluding to the gathering of the five perpetual individuals on the UN Security Council, in addition to Germany.

The foreign ministry statement comes ahead of a quarterly gathering Monday of the United Nations atomic guard dog International Atomic Energy Agency (IAEA) board of governors,

Which are probably going to discuss Iran's new limitations of some nuclear inspections.

"Remember: Trump failed to meet because of his ill-advised ‘Max Failure’," Khatibzadeh wrote on Twitter soon after his statement.

Tehran’s position is unchanged "with sanctions in place... Censuring is NOT diplomacy. It doesn’t work with Iran", he added.

Signed in 2015 by Iran and several world powers, including the US, the JCPOA placed significant restrictions on Iran’s nuclear program in exchange for sanctions relief. Former President Trump withdrew the US from the deal in 2018. Earlier, President Biden said the US will return to the JCPOA if Iran resumes compliance.
