Form 19 century with development of man in science and technology, needs of countries to each other is increasing. So one of ways induce states to comply with its international obligations under international law is international boycotts.
Although in some cases powerful states, as U.S.A. to abuse from this means for national interests, but use of boycott as “counter measure” and a kind of sanction from security council is legal.
The effectiveness of boycotts and sanctions in general depends, however, on the objectives pursued, highly dependent on the boycotting states and universal participation in application of the measures.
