Oil Transited at Major Strategic Locations, 2006
The geostrategy of maritime petroleum circulation is mainly composed of six major chokepoints, with two of extremely high importance; Hormuz and Malacca. Hormuz represents the most important strategic passage in the world, solely because of its access to the oil fields of the Middle East through the Persian Gulf, while Malacca is an active commercial point of transit between the Indian and Pacific oceans. From the Persian Gulf, two major axis of oil circulation service Western Europe and the United States (westbound) and Pacific Asia (eastbound). As the eastbound and westbound pressure on oil circulation increases, so does the need to maintain the integrity of the strategic passages supporting its trade. This is particularly the case for China, as its oil imports are stretching from the Strait of Hormuz, Malacca and the South China Sea, most of which are controlled by the United States.
