France, Britain and Germany issued a joint statement saying that Iran had recently accelerated the most sensitive violations of the JCPOA.
The statement, issued on Tuesday evening, said that Tehran had reduced the monitoring of the International Atomic Energy Agency and left the international community less informed about the status of its nuclear programs.
The statement added that Iran's nuclear program has become more advanced today than it was at any time in the past. It also indicated that Iran has retreated from the settlements that were reached after weeks of difficult negotiations, during which Iran made additional demands, according to the statement.
The three countries said that Iran's escalation of its nuclear program completely emptied the JCPOA, and called on Tehran to choose between the collapse of the JCPOA and the just and comprehensive deal for the benefit of the Iranian people and nation.
Tehran had renewed talk of its seriousness in negotiating and its insistence that this negotiation lead to the full lifting of sanctions.
A spokesman for the Iranian government stated that his country had submitted proposals that were in line with the terms of the nuclear agreement signed in 2015.
Warning from Washington
On the other hand, a warning was issued from Washington stating that if there is no rapid progress in the talks, the nuclear agreement will be empty of its content, according to its description.
She said she had already begun discussing alternatives with her partners and allies.
In parallel, the Iranian Foreign Ministry stated that there has been progress in negotiations between Iran and the International Atomic Energy Agency and that some differences have been reduced.
The Iranian Foreign Ministry added that it does not want to go into details of the progress of negotiations with the International Atomic Energy Agency, noting that an agreement with the agency may be reached soon.
France: the end of the road to saving the agreement
On Tuesday, France's ambassador to the United Nations, Nicolas de Rivier, said that the door to reviving the 2015 Iranian nuclear agreement is now open, "but we are rapidly approaching the end of the road" to reviving the agreement, which is emptied of its content by Tehran's progress in its nuclear program.
"We are approaching the point where Iran's escalation of its nuclear program has completely emptied the Joint Comprehensive Plan of Action (the nuclear deal) of its content," de Rivier told reporters.
He stressed that "the diplomatic door is definitely open for Iran to conclude an agreement now. It has to choose between the collapse of the agreement and reaching a just and comprehensive agreement," noting that "Iran's continued nuclear escalation means that we are rapidly approaching the end of the road."
