Economic sanctions are mainly used to protect domestic industries from international competitors.
help domestic industries gain more business.
punish nations for disobeying international law.
encourage nations to give up their nuclear weapons.

Found this on google, "National governments and international bodies such as the United Nations and European Union have imposed economic sanctions to coerce, deter, punish, or shame entities that endanger their interests or violate international norms of behavior."

Therefore the answer that i believe is the answer to your question is  Economic sanctions are mainly used to punish nations for disobeying international law. If i am wrong then I apologize.

Hope this helps, have a great day, have a wonderful weekend and stay safe!

Also Happy Halloween! :) :D :3
