The United Kingdom and Morocco concluded an Arrangement on the Status of Forces and Mutual Assistance in September 2013. The United Kingdom and Oman concluded an amendment to their existing 1994 Defence Co-Operation Agreement in May 2016. Both of these accords contain provisions on reciprocal concurrent jurisdictional arrangements. In order to effect those provisions, it is necessary to designate Morocco and Oman as countries to which the Visiting Forces Act 1952 applies.
