period 2003 - 2008 Venezuelan authorities seized the fifth-largest total quantity of cocaine in the world, behind Colombia, the United States, Spain and Panama. In 2006, the government's agency for combating illegal drug trade in Venezuela, ONA, was incorporated into the office of the vice-president of the country. However, many major government and military officials have been known for their involvement with drug trafficking; especially with the October 2013 incident of men from the Venezuelan National Guard placing 1.3 tons of cocaine on a Paris flight knowing they would not face charges. Administrative divisions Venezuela is divided into 23 states (estados), a capital district (distrito capital) corresponding to the city of Caracas, and the Federal Dependencies (Dependencias Federales, a special territory). Venezuela is further subdivided into 335 municipalities (municipios); these are subdivided into over one thousand parishes (parroquias). The states are grouped into nine administrative regions (regiones administrativas), which were established in 1969 by presidential decree. The country can be further divided into ten geographical areas, some corresponding to climatic and biogeographical regions. In the north are the Venezuelan Andes and the Coro region, a mountainous tract in the northwest, holds several sierras and valleys. East of it are lowlands abutting Lake Maracaibo and the Gulf of Venezuela. The Central Range runs parallel to the coast and includes the hills surrounding Caracas; the Eastern Range, separated from the Central Range by the Gulf of Cariaco, covers all of Sucre and northern Monagas. The Insular Region includes all of Venezuela's island possessions: Nueva Esparta and the various Federal Dependencies. The Orinoco Delta, which forms a triangle covering Delta Amacuro, projects northeast into the Atlantic Ocean. Additionally, the country maintains a historical claim on the territory it calls Guyana Esequiba, which is equivalent to about 160,000 square kilometers and corresponds to all the territory administered by Guyana west of the Esequibo River. In 1966 the British and Venezuelan governments signed the Geneva Agreement to resolve the conflict peacefully. In addition to this agreement, the Port of Spain Protocol of 1970 set a deadline to try to resolve the issue, without success to date. Largest cities Economy Venezuela has a market-based mixed economy dominated by the petroleum sector, which accounts for roughly a third of GDP, around 80% of exports, and more than half of government revenues. Per capita GDP for 2016 was estimated to be US$15,100, ranking 109th in the world. Venezuela
