The United States says it is disappointed that Iran has ruled out an informal meeting on the 2015 nuclear deal, but it remains ready to reengage in meaningful diplomacy on the issue.

Iran’s ambassador to the United Nations says Tehran is not interested in escalation of tensions with the United States, and unlike Washington, the Islamic Republic has no interest in making provocative moves.

A senior Iranian diplomat says the country is considering the European Union’s offer to host an informal meeting between Iran and other parties to the 2015 nuclear deal, with Washington also attending as a guest.

Iran’s foreign minister has urged the Biden administration to make up its mind about the policy it seeks to adopt vis-à-vis Iran and the 2015 nuclear deal, and stop making “meaningless and ambiguous” remarks.

Iran’s nuclear chief says the country’s distrust of the United States is based on realities, and Washington first needs to rebuild the missing trust.

Iran’s nuclear spokesman says the country is currently producing enough heavy water inside the country, and is even exporting the excess quantities to eight countries.

Iran says the Instrument in Support of Trade Exchanges (INSTEX), the financial mechanism proposed by Europeans to enable Iran to get round US sanctions, has failed to prove itself effective in the past two years.
