The Council of the European Union on Monday announced that it was reimposing a broad range of sanctions on Iran, citing Tehran's failure to comply with its nuclear commitments under the 2015 Joint Comprehensive Plan of Action (JCPOA).

The sanctions cover travel bans, asset freezes, and restrictions on trade, finance, and transport. They also include bans on Iranian oil, gas and petrochemical imports, the supply of energy-sector equipment and precious metals, as well as limits on Iranian banks and cargo flights.

The EU move follows the return of UN sanctions after Britain, France and Germany (the E3) triggered the accord's "snapback" mechanism on Aug. 28. Under the procedure, unless the UN Security Council votes to extend sanctions relief, pre-2015 UN restrictions automatically resume within 30 days.

The UN Security Council failed on Friday to adopt a resolution that sought to grant a six-month extension for the nuclear deal between Iran and the six major countries of Britain, China, France, Germany, Russia and the United States, as well as Security Council Resolution 2231 that endorsed the deal.

Explaining Friday's vote, Geng Shuang, China's deputy permanent representative to the United Nations, said his country was deeply disappointed at the result.

Geng reiterated that dialogue and diplomacy were the only viable ways to resolve the Iranian nuclear issue and preserve peace in the Middle East.

In response, Iranian Foreign Minister Seyed Abbas Araghchi said Sunday that the snapback procedure invoked by the E3 and the United States was "null and void," citing Washington's withdrawal from the JCPOA in 2018 and the European countries' failure to meet their obligations under the deal.

He stressed that Iran would continue to defend its sovereign rights and legitimate interests while remaining open to "genuine negotiations on an equal footing."
