Foreign Minister Abbas Araqchi expressed Iran’s willingness to achieve a just and balanced agreement over its nuclear program within the framework of the NPT, saying any deal must respect Tehran’s nuclear rights and guarantee the comprehensive and verifiable lifting of sanctions.

Reaching a deal with Iran will test the harder-line wing of Mr. Trump’s supporters in the Republican Party and whether they will fall in line with what would be a departure from their longstanding demands that Iran dismantle its nuclear program. More than 200 congressional Republicans urged him in a letter this week to stand firm with Iran.

For a third straight day, the United States on Wednesday issued sanctions targeting Iran as the Trump administration attempts to negotiate a new nuclear arms deal with the Middle Eastern country.
