ADOPTION DAY

Those announcements came on Oct 18, the so-called "Adoption Day" of the JCPOA, 90 days after the UN Security Council endorsed the Iranian deal.

The lifting of sanctions will take effect on Implementation Day, simultaneously with the (IAEA)-verified implementation of agreed nuclear measures by Iran, the statement said.

Therefore, sanctions on Iran will not be lifted immediately on "Adoption Day," as the United States has said that no relief from the sanctions will take place until the IAEA verifies that Iran has fully complied with the terms of the agreement.

To meet the JCPOA agreement, Iran would improve the transparency of its nuclear plan, downsize its capacity for uranium enrichment and change the structure of its heavy water reactor in exchange for international and Western sanctions relief.

In addition, under the JCPOA, all sanctions imposed on Iran will be lifted if the Islamic Republic proves it abides by the deal over the next 10 years step-by-step.
