The Biden administration on Friday restored some sanctions relief to Iran’s atomic program as talks aimed at reviving the 2015 nuclear deal enter final stage.
The US Secretary of State Antony Blinken signed several sanctions waivers related to Iran's civilian nuclear activities.
The waivers are intended to entice Iran to return to compliance with the 2015 deal that it has been violating since former President Donald Trump withdrew from the agreement in 2018 and reimposed US sanctions.
However, Tehran has demanded the restoration of all sanctions relief it was promised under the deal to return to compliance.
Friday's move lifts the sanctions threat against foreign countries and companies from Russia, China and Europe that had been cooperating with non-military parts of Iran's nuclear program under the terms of the 2015 deal, known as the Joint Comprehensive Plan of Action (JCPOA).
The Trump administration had ended the "civ-nuke" waivers in May 2020 as part of its "maximum pressure" campaign against Iran.
The campaign begun when Trump withdrew the US from the deal, complaining that it was the worst diplomatic agreement ever negotiated and gave Iran a pathway to developing a bomb.
