Each group of six to 10 students formed a delegation representing a country. ‘ ‘ ‘ The delegation members split up and attended committee meetings, where they discussed various foreign policy issues, including the Security Council, disarmament and international security, the North Atlantic Treaty Organization and the Pan American Health Organization. ‘ ‘ ‘ ‘This annual Model UN conference is all about raising and increasing awareness of these international issues,’ said Shimel. ‘We discuss everything from indigenous health care to debating the Vietnam War at this conference.’ ‘ ‘ ‘ At the end of the session, around 5 p.m., students met in the Assembly Room in the William Pitt Union for closing statements. Several of them received diplomacy awards for their performance during the meetings. ‘ ‘ ‘ The Global Solutions Education Fund, the University Center for International Studies and the United Nations Association of Pittsburgh also sponsored the event.
