The correct answer is embargo.
The trade embargo is a way of negatively influencing a country's trade relations with the rest of the international community. It is a way of retaliating against a country that behaves inappropriately, be it in the commercial, nuclear, political or ideological sphere.
The US has already imposed many embargoes on countries with a socialist tradition, such as Cuba and North Korea, and in countries with warlike purposes, such as Iran and North Korea itself.
