Multiparty negotiations often serve as forums for hammering out highly complex issues which require the expertise of participants with differing professional backgrounds: diplomats, soldiers, scientists, or international lawyers. Contributors to this ground breaking volume discuss situations in which professional cultures and their interactions color negotiations on issues relating to trade, environment or disarmament. This work provides insights into the potential benefits and the perils of enlisting professionals in multilateral discussions, including particularly useful analyses of the circumstances in which professional cultures can bridge diverse delegations, and those in which they will cause or deepen rifts. A readable volume on a topic of growing importance, Professional Cultures in International Negotiation is a must-read for both professional practitioners and scholars.
