Definitions of Diplomacy
Diplomacy is the management of IR through negotiations or the method by which these relations are adjusted or managed. Diplomacy tries to achieve the maximum objectives (national interests) with a minimum of costs in a system of politics where war remains a possibility.
There are two major forms of diplomacy. The simplest and the oldest is bilateral diplomacy between two states. Bilateral diplomacy is still common with many treaties between two states, and it is a main concern of embassies. The other form of diplomacy is multilateral diplomacy involving many states.
