Some call it the Bon Ton of diplomacy. Regardless of the fact that it has much in common with the bon ton, the protocol features one set of rules, which are far beyond the rules of decent behavior and it implies more obligingness. If the protocol is ignored in diplomacy, it may not only humiliate a person and make him/her rude and ignorant but it may entail far worse consequences not only for a person and his/her image but it may ruin his/her career and jeopardize the interests of those he/she represents. Diplomatic protocol is the sum of rules of conduct of official representatives of states and international organizations in the exercise of diplomatic functions in international relations. These rules are embodied in the Vienna Convention on Diplomatic Relations (VCDR), the Vienna Convention on Consular Relations (VCCR), the Convention on Special Missions, the Convention on the Privileges and Immunities of the United Nations and its Specialized Agencies, and in multilateral and bilateral treaties.
However, in a part of diplomatic ceremonial, many issues related to precedents and privileges have not been regulated by international norms, but rather have been left to be governed by rules of international customary law or norms of national legislation, tradition and customs of states.
The protocol in diplomacy works out the rules of hierarchy and order, thus demonstrating appreciation for partners. It respects working, official and social contacts with other participants in diplomatic activities. It encompasses numerous customs and habits, from guest seating etiquette to dinner suit or ensemble one needs to wear for suitable occasion.
It is quite understandable that various protocol rules have its degree of obligingness and avoiding the same may seriously harm and disturb not only diplomatic functions but may jeopardize bilateral relations between the two countries. Other rules are less mandatory and its ignorance and lack of respect of the same implies bad diplomatic work and it may cause smaller incidents impacting a person alone affected by this and the one who made mistake and was not aware of the protocol etiquette.
