Generally speaking, freelance diplomacy is a sort of self-financing diplomatic representation that is utilised by governments who, on the whole, cannot afford to retain full-time skilled diplomatic advisers.
A "freelance diplomat" is someone who is engaged for a particular purpose or who is occasionally employed on a long-term basis to operate a delegation, mission, or embassy on a certain country's behalf. They may also be used to encourage foreign direct investment in the nation for which they operate. It is regarded to be a performance-based partnership in which the diplomat gets compensated only on the basis of his or her achievements.
