Sweden Explains It All: EU Terrorism sanctions backgrounder

From the Swedish regulatory authorities, here's a good background to the anti-terror sanctions promulgated by the United Nations:

The UN Security Council has introduced two separate sanctions regimes – which are binding on member states – to combat international terrorism. EU member countries implement these sanctions regimes jointly in common positions and EC regulations.

Sanctions regime 1267/1989

The name of this regime comes from Resolution 1267, which the UN Security Council adopted in 1999. The regime is based on several different UN Security Council resolutions that previously applied to the Taliban in Afghanistan, Usama bin Laden and al-Qaida. The rules are now gathered in Resolution 1989 (2011) and cover sanctions against al-Qaida and against individuals, groups, undertakings and entities associated with this network. In connection with this Resolution, the sanctions against the Taliban and Afghanistan have been transferred to a separate sanctions regime, see sanctions against Afghanistan.

Sanctions regime 1373

This regime was established in 2001 through UN Security Council Resolution 1373 as a response to the attacks of 11 September 2001. The sanctions in this regime target individuals, groups and entities considered to be involved in terrorism over and above those covered by the 1267 regime. In this case, the UN has left it to the member states themselves to determine the targets of the sanctions.
