(MENAFN) The European Union announced on Sunday that it will reimpose UN sanctions on Iran “without delay,” after efforts in the Security Council to postpone them failed earlier this week.

“The European Union will now proceed to implement the re-imposition of all previously lifted UN and EU nuclear-related sanctions without delay,” EU foreign policy chief Kaja Kallas said in a statement released by the bloc’s diplomatic service.

Kallas emphasized that the snapback of sanctions should not mark the end of nuclear diplomacy with Iran, describing the matter as a “key challenge” for both regional and global security. She added, “It is the position of the European Union that a sustainable solution to the Iranian nuclear issue can only be achieved through negotiation and diplomacy. In line with the UNSC Resolutions that have been brought back into force today, I will remain engaged with all relevant parties, including Iran, in support of political and diplomatic efforts to find a negotiated solution.”

She also urged Iran to “fully resume cooperation” with the International Atomic Energy Agency promptly, in accordance with its “legal obligations” under the Treaty on the Non-Proliferation of Nuclear Weapons.

The UN Security Council on Friday rejected a draft resolution seeking to extend the 2015 Joint Comprehensive Plan of Action (JCPOA) on Iran’s nuclear program until April 18, 2026. The JCPOA, endorsed by the Security Council, requires Iran to limit uranium enrichment and permits international inspections to ensure its nuclear activities are exclusively for peaceful purposes.
