diplomacy is the art and practice of conducting negotiations between representatives of states. it usually refers to the conduct of international relations through the intercession of professional diplomats with regard to a full range of topical issues. diplomacy entails influencing the decisions and conduct of foreign governments and officials through dialogue, negotiation, and other nonviolent means.
diplomacy is the main instrument of foreign policy, which consists of the broader goals and strategies that guide a state's interactions with the rest of the world. international treaties, agreements, alliances, and other manifestations of foreign policy are usually negotiated by diplomats prior to endorsement by national politicians. diplomats may also help shape a state's foreign policy in an advisory capacity.
since the early 20th century, diplomacy has become increasingly professionalized, being carried out by accredited career diplomats supported by staff and diplomatic infrastructure, such as consulates and embassies. subsequently, the term "diplomats" has also been applied to diplomatic services, consular services and foreign ministry officials more generally.
