Under the terms of the JCPoA, in exchange for the lifting of nuclear-related sanctions, Iran agreed to restrict certain nuclear enrichment programmes. Consequently, most UN and EU sanctions were lifted on 16 January 2016, but some measures still remain in force.
The JCPoA provides for the lifting of the remaining EU sanctions related to nuclear proliferation by 2023, and all EU and UN sanctions by 2025, subject to Iran’s compliance with the agreement.
