Fifty percent of Citgo was sold to Petróleos de Venezuela, S.A. (PDVSA) in 1986, which acquired the remainder in 1990, resulting in the current ownership structure. In September 2010, in connection with the centennial of its original owner, Cities Service Company, Citgo unveiled a new retail design. Within five years, Citgo planned for all locations to display the new street image. With full ownership of Citgo, PDVSA at its peak controlled 10% of the US domestic oil market, creating a lucrative export chain from Venezuelan soil to American consumers, as the two largest buyers of Venezuelan petroleum are the United States and China, respectively.
