Explanatory Note

(This note is not part of the Regulations)

These Regulations amend the Iran (Sanctions) (Nuclear) (EU Exit) Regulations 2019 (“the 2019 Regulations”) to reflect the United Nations (“UN”) obligations imposed in relation to Iran by virtue of paragraph 12 of UN Security Council Resolution 2231 (2015).

In particular, the purposes of the regulations (regulation 4) have been updated to reflect the new United Nations obligations in relation to the situation in Iran.

The definitions of “missile-list goods” and “nuclear-list technology” which are subject to prohibitions on the export to, and imports from, Iran, and related activities, as well as other trade restrictions in relation to Iran, are also extended (see the amendments to regulation 34 of the 2019 Regulations).

The Regulations add a new exception to the prohibitions in regulations 12 to 14 of the 2019 Regulations (asset freezes and making funds available to or for the benefit of designated persons) to ensure payments can be made in respect of certain funds borrowed by or on behalf of the Treasury (including gilts) and that those payments can be facilitated. They also extend the purposes for which the Treasury may issue licences to permit activities which would otherwise be prohibited under UN financial sanctions.
