An embargo is a tool used by governments to restrict the movement of goods from one country to another. It’s used as a type of economic leverage, and can involve anything from stopping the transportation of certain products to outright banning all commerce between parties. Although an embargo may seem like an extreme measure, it’s one of the most effective ways for countries to put pressure on one another in order to facilitate changes in policy or diplomatic relations. Embargoes are also used to protect domestic industries from foreign competition and to help protect the interests of citizens.
