In the 1990s, the experiment of separating party and state posts, which led to conflict during the Tiananmen Square protests of 1989, was terminated. In 1993, the post of President was taken by Jiang Zemin, who as General Secretary of the CCP and Chairman of the Central Military Commission, became the undisputed top leader of the party and the state.[24][25] When Jiang Zemin stepped down in 2003, the offices of General Secretary and President were once again both given to one man, then–Vice-President Hu Jintao, the first vice-president to assume the office.
