Iran says it is not the right time to negotiate a 2015 nuclear deal with world powers.
The United States has expressed frustration with Iran’s statement.
A White House spokesman said the United States was ready to pursue meaningful diplomacy with Iran.
It should be noted that Donald Trump withdrew from the nuclear deal reached between Iran and other world powers in 2018, after which Iran also announced its withdrawal from the agreement on its nuclear program.
However, the new US president Joe Biden has once again agreed to join the nuclear deal.
According to media reports, a US State Department spokesman said that the United States has accepted the invitation of the European Union to negotiate a nuclear deal with Iran.
