2- A boycott consists of refusing to buy, sell, or practice any other form of business or other relationship with an individual or company considered, by the participants in the boycott, as authors of something morally reprehensible.
3- An embargo is a commercial and financial penalty applied by one or more countries against a State, group or person. Embargos can include various forms of trade barriers, tariffs and restrictions on financial transactions.
