Jiang was referred to as a "core" in official documentation for the first time on November 9, 1989, at the closing of the Fifth Plenum of the 13th Central Committee, which called for the party to "closely rally around the party center with Jiang Zemin as its core."[3] The phrase was then oft-repeated as a familiar slogan in official party documentation thereafter,[2] until the succession of Hu Jintao as party leader in 2002.[4]
