trade embargo

Explanation:

In trade and international politics, an embargo is the prohibition of trading and negotiating with a particular country.

It is usually declared by one group of nations against another, in order to isolate it and place its government in a difficult internal situation, since the effects of the embargo often cause its economy to suffer.

The embargo is normally used as a political punishment for certain prior policies with which it is not agreed, although its economic nature often leaves enough space to doubt the true interests that benefit from the measure. Historically, an embargo is a war certificate. The typical reaction to the submission to an embargo is the development of autarchy.
