Economic sanctions are imposed by a government to show disapproval of another government's actions and to attempt to influence its future conduct. Economic sanctions involve the withdrawal or suspension of trade or financial relations.
The USA entered into a trade embargo with the USSR for the latter's invasion of Afghanistan, and several industrial countries have engaged in economic sanctions against South Africa in protest at the Platter's policies of apartheid. In 1989 India closed 13 of 15 entry points to the landlocked Kingdom of Nepal creating shortages of food, medicines and fuel.
