Adipec is the world's largest annual energy exhibition and conference, held in Abu Dhabi and hosted by the Abu Dhabi National Oil Company. This action by the American companies comes at a time when the State Department of the United States also ordered the departure of several diplomats from Saudi Arabia last week, and the American officials also announced the evacuation of their families from several other missions in the region. - Link.
