Consultations in Vienna to re-establish the Joint Comprehensive Plan of Action (JCPOA) on the Iranian nuclear program are proceeding very slowly, said on Tuesday by French Foreign Minister Jean-Yves Le Drian, speaking at the Foreign Affairs Committee of the National Assembly of France.

Discussions are going on, but, from our point of view, too slow, the minister said.

This, he said, reduces the chances of reaching an agreement on the Iranian atom, which would meet the interests of the parties, within a realistic time frame.

The JCPOA was signed with Iran in 2015 in order to overcome the crisis over its nuclear program by the permanent "five" of the UN Security Council and Germany.

The previous US President Donald Trump made the decision to withdraw from the JCPOA in 2018. The current head of the American administration, Joe Biden, has repeatedly signaled its readiness to return the United States to a nuclear deal with Tehran.
