The UN Security Council votes to impose tough sanctions on Yugoslavia, which effectively refers to Serbia since most other Yugoslav republics have declared independence. The embargo requires all the countries of the world to cease trading in any commodity, including oil, and to freeze all of Serbia’s foreign assets. All air traffic links are suspended as well. Sales of medicine and food are exempted. The sanctions are meant to pressure Serbia to agree to a cease fire in the war in Bosnia. [New York Times, 5/31/1992]
