Extraterritorial sanctions as a challenge in the US-EU relations

The United States of America is a subject of international relations which took the leading position in application of unilateral sanctions, especially extraterritorial restrictive measures. The main target of the US extraterritorial sanctions are legal entities and individuals which are in the jurisdiction of third countries, namely member states of the European Union. The increasing sanction pressure against Iran in the 2nd half of 2010s has brought the problem of American extraterritorial measures in the US-EU relations to the fore. Consequently, the aim of this research is to reveal the contradictions between the USA and the EU due to the strong influence of secondary sanction on the European business and examine the main countermeasures taken by the EU authorities in this regard.
