The international community can adopt sanctions against a country if it violates international conventions and agreements. This can happen, for example, through human rights violations, ceasefire violations or the development of illegal nuclear programmes.
Sanctions can be diplomatic or economic in nature. They aim to change a specific behaviour or policy, such as a violation of international law or human rights, or a policy that does not respect the rule of law or democratic principles.
The Danish Maritime Authority administers, among other things, the rules on the implementation of UN and EU sanctions in the area of ship registration (Law nr. 1546 of 19. december 2017).
You can find out more about the division of competences between the authorities at (in Danish): Ministry of Foreign affairs homepage (Competent authorities).
A current and comprehensive overview of current EU sanctions can be found at the EU Sanctions Map.
