Vienna is the headquarters of the UN Office on Drugs and Crime
Background
Austria's standing in international affairs rests less on its size than on the bodies it hosts, and the United Nations Office on Drugs and Crime is one of them.
UNODC has its headquarters in Vienna, Austria.
It was started in 1997.
It supports governments, criminal justice institutions and law enforcement in three areas: policy, data and research, and training and support.
It runs a network of field offices across the globe covering some 150 countries, and most of its staff and projects are on the ground rather than at headquarters.
In plain words
UNODC United Nations Office on Drugs and Crime — The UN body that works on drugs, crime, corruption and terrorism, based in Vienna.
Field office Field office — An office an organisation keeps in the country where the work is done, rather than at its headquarters.
