In 1997, Chung Ju-yung appointed Mong-hun as the group's co-chairman. In 2000, after Ju-yung's eldest son, Mong-koo, attempted to oust Mong-hun, Ju-yung made Mong-hun the group's sole chairman. Later that year, Ju-yung announced that he and his sons would resign from all management positions at Hyundai companies, except Mong-hun would remain the chair of Hyundai Asan. However, Mong-koo remained the chairman of Hyundai Motors and Kia Motors.
