Sanctions are intentional restrictions with the primary purpose of hurting a particular country or individual’s finances. Sanctions can vary in a wide range, it can literally be anything from asset freezing to ban on import/export of goods to travel bans on individuals. The long list of sanctions imposed is basically a hard warning to Russia, which can get even worse if the war keeps on developing further ahead. The sanctions are a win-win situation, the sanctioned country is defeated outside the battleground without losing the lives of people.
